主题：【原创】围绕脑科学而发生的若干玄想 -- 鸿乾
家园 玄想9：脑作为信息处理器的内在的动力原理 刚才检查了一下，发现上一个玄想是去年5月写的。就是说差不多1年没有来写玄想了。还是应该继续。这次的玄想就从益者三友的评论说起。他去年做了一个评论：
真正的本质事实是，大脑细胞和身体中的其他细胞都是从一个单一的受精卵分化出来的。而原始动物的神经细胞是从基本的上皮细胞分化演化出来的。大脑细胞和小肠，膀胱，胰脏细胞没有什么大不同，都是从表皮细胞分化出的。他们里面是同一套DNA。他们有几乎相同的内部结构。其基本的膜结构是完全一样的。小肠和大脑细胞，运用同样的细胞膜通道做基本工作原理。大脑细胞交换信号分子，打开关闭信号通道，和小肠分泌消化液吸收肽没有任何差异。这个评论要分两个方面看。首先，是对的。神经细胞也是细胞，因此具备和其他细胞相同的共性。因此，这个观点，即神经细胞的整体作为信息处理器，没有什么超原理。其次，这个评论忽略了一个很重要的方面，那就是，很可能精细结构，一些看起来非常细微的精细结构，可能产生巨大的宏观效果。例如，那个FOXP2基因所展示的，就是这种情况。那么神经细胞的这些精细结构是什么呢？这才是思考的关键。
进一步，我们再看益者三友的评论：
脑科学，我觉得现在相当于1930年研究遗传规律。我反复回想一下看过的《双螺旋》。我觉得在1930年，即使没有进一步的科学实验结果，如果有人真的非常仔细的思考，通过科学直觉，也能够根据有限的事实，反推出遗传基因的核心规律。这种科学直觉，在很多重大原理性的发现起作用。比如，化学周期表，完全是科学直觉。我感到这个评论很好。的确，现在已经积累了非常多的知识，但是都是杂乱的，没有理出一个规律。很可能的确可以根据比较有限的事实，反推出核心规律。但是，这个工作很不容易。最近不见益者三友河友来参与评论。不知是否有了更新的心得。
我个人感到，脑作为信息处理器，而且是很有效的信息处理器，必然有所宏观规律可供我们把握。而促成这些宏观规律的，就是神经细胞的内在动力。我感到，可能从神经细胞的内在的动力原理入手，是一种理解这个信息处理器的路子。
那么，神经细胞的内在的动力是那些东西呢？如果很深入地看，肯定非常复杂。但是，那种复杂的看法未必是正确的有效的，如果我们的目的是了解和把握脑作为信息处理器的宏观规律的话。因此找到一个合适的程度来看这个内在动力，就是需要的。不知大家对此是否有想法。
家园 FOX2的原理并不清楚 Whether FOXP2 is the main driver of the evolution of language in humans, or just a cog in the wheel, remains unclear, says Fisher. "It is worth remembering that a large number of genetic differences distinguish the brains of these two species, not just the substitutions in FOXP2," he adds.否则通过分析这个基因对脑神经的改变（比如老鼠实验那段）应该能够对理解智能其作用的方式有帮助，但是能够了解的只是老鼠学习走迷宫的能力加强了，但是为什么却仍然不了解。只是提到树突加长了。
这说明脑神经科学的手段仍然十分有限，不但因为这是一个跨生物，化学，物理，数学的多学科的困难，就是在生物学科内，在脑神经的研究上也分出多层分支，各做各的实验，很难得出一个宏观规律性的结论。
同样用鸟飞行那个比方，这里面有人研究鸟的生物学，从基因到细胞到生物化学，同时有人去研究物理上的空气动力学，而最后得到突破的是空气动力学方面了解了飞行的宏观规律。
当然不是说信息在大脑中的存储，运动，不受细胞级别的动力影响，但是这个作用更主要的是去帮助认识信息在脑神经网中的宏观规律，换句话说，需要了解的仍然是信息是如何发生相互之间的作用的这个规律。
与鸟飞行原理研究不同的是，那个是生物体与外界之间或生物体内部之间的动力学，本质上不同物体之间的作用，生物体也是一种物质。但是脑神经本身是没有信息这个物质的，神经细胞发生化学反应客观上传递了信号直至生物体出现反应，信号只是个抽象概念，是人类使用的把一个机械能力抽象为信息作用的概念工具。
另一个干扰是人因为这个信息作用的强大以至于出现了认知力，远远超越了简单的机械作用。于是，在这个问题上不如去研究老鼠等简单的脑神经原理，而避开了人类认知力来源问题的困扰，专注于解决信息作用的原理这个问题，甚至简化为一系列复杂的物理化学反应的结果。现在看来还是手段的缺乏，不能大范围的把老鼠大脑中细胞级别的活动全面的实时的去观察。
如果把人类大脑的研究比作全球天气预报的话，这个复杂系统的宏观规律可能是NP问题，永远无解。但是在局部上，在部分特定功能上，类似地区性天气预报，在外部条件一定的情况下，掌握其规律还是可能的。
家园 推荐：语言基因的一些方面 关于语言基因的报道： 外链出处
基本的故事是这样的：FOXP2基因是研究英国的某家人时发现的，这家人好几代都有语言障碍。这家人的FOXP2基因有畸变。后来发现，这个基因在所有的脊椎动物中都有，非常古老。又发现其功能和学习运动功能学习肌肉功能直接相关。这个基因一直演变比较缓慢。
德国一位做古人类基因研究的研究者发现，人和尼安德拉人的这个FOXP2基因，是一样的，但是人和黑猩猩的这个FOXP2基因有所不同（其实很小了，这个基因产生的蛋白仅有两个氨基酸的位置不同）。因此推算这个FOXP2的进化是发生在大概50万年前。
虽然这个进化不大，但是，很可能是非常关键的一步进化，使得人类拥有了的更精细的语言能力。据说，这个变化使得若干精细的肌肉运动的学习能够进行，因此推进了语言能力的发生。
他们进一步，把这个基因转进老鼠的基因里面。这些转基因的老鼠，当然仍然不会讲话，但是，其脑内组织，发生了相当有趣的变化。
更多的，我就不懂了。
但是，这里的教益是很有趣的。那就是，脑组织的能力，和一些精细结构直接相关，这些精细结构甚至可以产生完全不同的宏观的效应。如果FOXP2没有演变，可能猿人就还是猿人，没有办法进化到人，因为可能无法有效进行语言交流。因此类脑计算技术可能也和某些非常精细的结构有关。

家园 推荐：关于稀疏表达的最原始文献之一 Sparse Distributed Memory 外链出处
引用其中的一段：
It is a failure of the rationalistic philosophy deeply rooted in Western thought (1). That philosophy has produced in many disciplines a search for models that combine context-free (meaningless) elements into systems governed by formal laws. Not only have information-processing models of cognition fallen short in computer science, corresponding formal models have fallen short in anthropology, economics, linguistics, political science, psychology, and other disciplines. These shortcomings have prompted a new examination of what it means to be human, a search for a philosophy that respects the mystery of individuals and the biological roots of all learning.我想，这段话对很多讨论都是有教益的。寻求知识的生物之根，的确是一种想法，一种冲动，甚至一种时髦。至于是否能够产生有益的效果，谁又知道呢？其实对现有的科学体系的长远前景，谁又知道呢？
但是不管如何讲，在众多前驱者的努力下，类脑计算已经站住了脚跟，而且正在壮大。我们应该很快可以看到相关硬件的出现。
家园 你还没回答我那个问题 “我们喜欢类比和联想就是底层应用字典编码倾向的表层反映”是什么意思？
我了解字典学习，但是类比与联想不知道有什么关系。
家园 我的理解是这样的：类比和联想其实是神经系统自然的动作 而不是外部刻意追求的。
具体怎么讲？首先从反面讲，即从现有的计算技术中的记忆存储和相应的功能讲。在现在的计算机中，你存一个图像就是一个图像，你取出来，还是那个图像，非常精确，如果有所误差，你就根本取不出来。而且这个图像的记忆和对这个图像的理解一点关系都没有，记忆是记忆，理解是理解，记忆是存储体中的，理解是存储外面的软件的运行的结果。因此，这个计算技术体系中，不可能产生类别和联系，即使有，也不是自然产生的，而是外部刻意追求而加进去的。扩大了讲，就是说，基本上没有可能产生智能。
但是在脑中，完全不同。记忆的东西，是神经系统分解进而理解（这个理解的含义，请注意，有所不同）的东西。因此，在这个基础上，如果有所误差（有意的，比如说放开了幻想，或无意的，比如说醉酒），那么就自然产生有些不同的记忆提取，但是其主体又是同样的。这样就产生了类比和联想的神经基础。现在大家都比较认同，这其实是智能的最基础的属性和特征。
当然了，具体究竟神经系统是如何分解信息，进而在不自觉的程度上做了理解（含义，再次提醒），又怎么做的存储，这些都是未知的。但是，我认为Hawkins对这些方面正在做的工作是非常好的，非常有意思的。遗憾的是，整个学术界对此做了几乎全部的冷待遇。他做的对或者错都不重要，但是重要的是，是一个很好的方向。
这个Pentti Kanerva的工作，也应该对Hawkins的影响很大。他是Hawkins的研究所的成员。
这位朋友说的：底层应用字典编码倾向的表层反映，其实就是说如何分解信息等（他称为字典编码）。现在的DNN也不是没有这个分解信息。他们的分解基本上是解很大的不定线性方程组，但是加上极值限制。这种分解，有很强的数学指导，因此容易为大家接受，分解也就是线性组合，理解起来容易。但是，可以明确讲，我的观点是，这样的数学，明显不是脑中的活动，差得很远，恐怕因此效果就差了。
家园 "类比和联想的神经基础", & "量子力学的心脏” first of all, I like your this post so much, thanks. it is very helpful, making me keep coming back, again, the great global internet, needless to say further, then we have TG's GFW;
1.
now, before going into prof 张永德's "量子力学的心脏” (which carries a lot of 类比和联想 vs your 神经基础" as "智能的最基础的属性和特征"). let's get TG out of way.
ccthere.com used to be very diversified with a lot of excellent science (generally speaking, including things like AI) posts, not anymore, likely because of this Chinese blood fueled TG fans syndrome going on all over the place, as we all know, and in general Chinese wants to see a strong and prosperous china coming out of pacific, the so called china dream. Now, X has taken over, a historical juncture, people got excited. big sentiments improve, boy, sell them something(:).
I think I have written about TG's long term political and economic picture fairly "objectively" from physics point view in my recent post, yes, an individual's wild guess of something big such as TG, OMG;
still, TG will be here with us for long long time, more likely in working closely with MD together (surprised (:)?), and as I said, nobody knows when looking back in future, TG=a good or a bad thing to the Chinese nation, it's beyond any individual or organization's ability. so arguing that type of questions=waste of time, for most average individuals.
do you have time to waste?
2.
what we do know fairly well is GFW, and as I wrote quite bit about it, it is a physics reality, it is also a financial opportunity, such as various financial arbitrage in & out of GFW, because it is an information/logic gap, between US (and others) and china, and we all know, huge amount of money activities across GFW, all kinds of it, daily.
so, what is point? the point is if there is an 100 USD clean money on the ground "carelessly" dropped by GFW, are you going to pick it up and throw it into your own pocket?
how about those opportunities of $1k, $2k USD, etc?
basically, X redgen II: no poltical 體制改革 (TG actually get squeezed by MD politically, global & domestic, likely more to come), but pushing urbanization forward to keep money tree growing higher in china garden (to keep game going and to seduce uncle sam's wall street folks), big time;
with that, 體制套利 becomes global across GFW, for TG & MD senior insiders, for Chinese TG ass kissing BAT internet elite, they got their their way of making big money too, obviously, and for many other WS folks, play "估值套利,成交套利, IPO 套利 " etc, across GFW;
now, where all these 利 comes from? as I posted before, X dynasty macro trade fundamentally is a trade of short the 7億 Chinese farmers, would you, chairman X?(:)
just do it, baby(:).
as to 防空識別區 BS, just a fake political 烟幕弹, but a real military budget and all the beautiful goodies for PLA, can TG afford making PLA not happy at all?
in terms of physics, you would need a huge amount of energy to change all these macroscopic paths of US TG system, where and how to get that kind of energy?
if you don't have enough energy (位能= twice of 動能 for a sytem, normally)to change it, then respect 惯性, and I would think, that as smart as TG is, TG would have figured these thing all out already: uncle sam's garden, global, well diversified, stable, vs TGchina: 有序参量=1, actually highly unstable, subject to any local 量子事件 induced 相變 at system level, QFT model can't really produce numbers, we are in this social science across GR time space. BUT QFT does produce tons of uncertainties, for TG at the top of the curve, those many of uncertainties are all pointing downward, is that scary?
But, obviously, uncle sam's national team of all kinds of brains are working on it, putting a little fire here and there, once a while, making X redgen II hard to sleep well at night because of those damned but never go away bad dream of 量子事件, etc.
so, what to do? make money in china garden, and use branches off china money tree to stick into the ass of uncle sam(:).
uncle sam: well, that is a little bit of pain & bloody, in terms of white trash unemployment, but short term, it may not be a bad deal, our boys got big money from china.
money never smells, and donate some to uncle sam political elite, did US supreme court just ok that?
3.
"量子力学的心脏”
first of all, this is not easy stuff, how difficult and how beautiful 量子力学 is, you can only know after you have learned it, worked at least on some real life 量子力学 apps, and still, learning and understanding it is a forever journey.
now, some rough analogies:
带A-B效应的Young氏双缝实验
经典力学中，Maxwell方程和Lorentz力公式都是用场强 ( 场强 is always local, or generally speaking, classical physics law are all local, 智能 obviously is not local, TG is definitely not local(:), kind of why TG is super smart(:)) 表达的。
actually, SR itself is still local or 经典, QFT kind of global, SR version of 量子力学, all because of Dirac's famous equation.
(extra "juice": in that sense, TG is very smart, now, how about uncle sam? the two smartest person in the world, are they going to kill each other (small probability, TG work hard to keep it that way, how? get uncle sam's businessmen coming into TG's china garden, treat them well, for example) or working together in some form?)
this corresponds to
"现在的计算机中，你存一个图像就是一个图像，你取出来，还是那个图像，非常精确，如果有所误差，你就根本取不出来。而且这个图像的记忆和对这个图像的理解一点关系都没有，记忆是记忆，理解是理解，记忆是存储体中的，理解是存储外面的软件的运行的结果。因此，这个计算技术体系中，不可能产生类别和联系，即使有，也不是自然产生的，而是外部刻意追求而加进去的。扩大了讲，就是说，基本上没有可能产生智能"
I posted that semicomductor is still a macroscopic (kind of 经典物理) material & energy transfer done by classicl 電子, with a 量子化的 声子 field and interactions of 电子声子 working in the background, kind of, so semiconductor as we know today, cannot give us a 量子 computer. for a 量子 computer, we need to have 电子 work in "qm wave" form, not the classical 电子 as it is working now in semiconductor, producing all kinds of 电子 computer.
once 电子 start working in some kind of "qm wave" form in room temperature, etc, it will have quite bit of AI capability to pop out.etc. again, this is because a 电子 working as "qm wave" can be global, obtaining some kind of organization power, the way TG does
(extra juice: TG will never share power with any other Chinese elite, whatsoever whomsoever, fxxk u, if u dare to dream that way, baby, and pls respect uncle TG's privacy(:))
before that, as you said very well:
"这位朋友说的：底层应用字典编码倾向的表层反映，其实就是说如何分解信息等（他称为字典编码）。现在的DNN也不是没有这个分解信息。他们的分解基本上是解很大的不定线性方程组，但是加上极值限制。这种分解，有很强的数学指导，因此容易为大家接受，分解也就是线性组合，理解起来容易。但是，可以明确讲，我的观点是，这样的数学，明显不是脑中的活动，差得很远，恐怕因此效果就差了"
we all know without x-ray, there would be no DNA, period.
4.
without going into specifics, one way to imagine the "AI" 电子:
"全部宏观电磁实验表明，只有规范变换不变的场强才有物理意义。量子力学中，电磁场下Schrdinger方程虽然是用电磁势表达的，但由于方程具有定域规范变换不变性，因此人们一直认为，如同经典力学一样，量子力学中也只有电磁场场强才具有可观测的物理效应，电磁势不具有直接可观测的物理效应。"
ok, focus on the following:
blabla, "这个相因子存在表明，即使粒子路径限制在磁场强度为零的区域，粒子不受定域的动力学作用，但电磁势(沿粒子路径的路径相关积分)仍会影响到粒子的位相"
磁场强度为零, game over, according classical 电磁场 physics, kind of, roughly speaking.
but in this "AB效应" thing, somekind of global 电磁势(沿粒子路径的路径相关积分)can still keep the game going, even local 磁场强度为零;
needless to say, if "AB效应" (already observed in lab long time ago, first in japan?) can work its way into computer, then we could have all kinds of potential apps coming out.
of course, "AB效应", 規範場, etc, physics got a long way to go in that direction, in terms of theories, tons of challenges, such as 拓扑, bordering into Riemann geometry /GR area, etc. a very promising field, waiting for smart folks to dig gold out of it.
5.
so, what is fxxking points? where to get my $1k USD?
as I wrote zillions time before, it is all about modeling, about using right logical model in analyzing and hopefully solving real time problems, regardless of what you actually do, do you have to wait until QM computer and GOOG AI robots coming out on sale at discount, with a many Chinese 山寨機 all over the 3rd world?(:)
does that make sense?
unless, you are very close to TG top tier elite, then life is beautiful for many years to come, just enjoy it while still alive, why fxxking working at all(:)?
------------------
但是，1959年Aharonov和Bohm提出, 在量子力学中，在某些电磁过程中，具有局域性质(因为是关于空间坐标的微商)的电磁场场强不能有效地描述带电粒子的量子行为，电磁势有直接可观测的物理效应。下面只对磁A-B效应作一简明分析。电磁AB效应的推广和进一步讨论详见文献张永德.量子力学.北京: 科学出版社，2010,第9章..
在缝屏后面两缝之间放置一个细螺线管。通电后管内场强≠0;但管外场强=0，矢势场强≠0。这个细螺线管产生一细束磁弦。下面的理论分析表明,相对于没通电的情况来说，通电后，接收屏上干涉花样在包络(干涉条纹极的轮廓线)不变的情况下所有极值位置都发生了移动。电流改变时，峰值位置也跟随改变；电流反向，峰值位置也反向移动。下面对此作一简单分析。
Young氏双缝实验能够做成功，必定要求两缝处电子波函数的初始位相差是固定的。不失一般性，假设初始位相差为零，将两缝合并成为A点，简化成图1.6(b)。通电之前，p22μφ0(r)=Eφ0(r), φ0(rt)=φ0(r)e-iEt/c点的合振幅为f(0)c=f(0)1(c)+f(0)2(c)。通电之后p→p-ecA。于是12μp-ecA2φ(r)=Eφ(r)
φ(r,t)=φ(r)e-iEt/直接验算即知，此方程的解为φ(r)=ei ec∫rAA(r′)·dr′φ0(r)注意，这里的相因子在B≠0的区域与路径有关(不仅与两端点有关)，因而是不可积的；只在B=0的区域与路径无关(这正说明，磁场毕竟是一种物理的实在，不能通过数学变换将其完全转化为纯粹相因子).
图 1.6
这个相因子存在表明，即使粒子路径限制在磁场强度为零的区域，粒子不受定域的动力学作用，但电磁势(沿粒子路径的路径相关积分)仍会影响到粒子的位相。

一，近代自然科学的基本特征
张永德
家园 嗯，这个要好好想一想 现在似乎都对稀疏的作用比较认同，hawkins特别大力推崇，但是做法比较机械，如你所说，没有使用数学方法。最近看了稀疏信号与压缩感知的一些文章后，稍微理解了些为什么这个方向有可能符合大脑的信号接受原理，换句话说，稀疏信号识别而不是原信号恢复，反而很象大脑的运行过程。
如果在稀疏信号的条件下做信号存储，所谓的字典学习（dictionary learning)，是不是类比与联想的过程就是必不可少的步骤？这个还是不很清楚，大概有做信号处理的行家来给分析一下就好了。
家园 量子 computer can do "类比和联想" first of all, this is a very important point, thanks you two for bringing it up in the discussion.
鸿乾：
"在现在的计算机中，你存一个图像就是一个图像，你取出来，还是那个图像，非常精确，如果有所误差，你就根本取不出来。而且这个图像的记忆和对这个图像的理解一点关系都没有，记忆是记忆，理解是理解，记忆是存储体中的，理解是存储外面的软件的运行的结果。因此，这个计算技术体系中，不可能产生类别和联系，即使有，也不是自然产生的，而是外部刻意追求而加进去的。扩大了讲，就是说，基本上没有可能产生智能。

1.
now, without going into specifics, human brain "类比和联想" can be approximated by future quantum computer's "量子態相互作用";
roughly speaking, in real world mesoscopic (vs newton macroscopic and qm microscopic, kind of) 纳米 material & technology, we already have 隧道效应与隧道电流 due to
some kind of "量子態相互作用 (kind of 心有灵犀一点通 between people across SR/GR time/space if you will, as an analogy)", where we don't have 载流子(some kind of quasi "real" 粒子, 準粒子 )加速和碰撞, so it is real 量子效应 (still local, non-sr, & if SR, we get into QFT) in room temperature, functioning kind of like our brain doing 量子 computing everyday;
similarly, in 超導 material and technology, we basically have figured out how to utilize "量子態相互作用" tricks, as opposed to the conventional/classic 粒子 such as 電子 doing heavy lifting of energy transfer stuff by themselves only, now we have an "quantum organization" at work, still largely @mesoscopic level.
"Mesoscopic physics就是「介觀」物理. 一. 「介觀」物理. 「介觀」物理的主要研究對象是介於「微觀」尺度與「巨觀」尺度之間的物質性質。微觀的尺度是指原子、", etc.
2.
生物大分子尺寸为纳米级 or close, and again roughly speaking "量子態相互作用" induced 隧道电流 in 纳米 stuff in many case are due to "能带简并" stuff, and I would guess that very likely in our brain, we have similar 神经元"能带简并" (very organized, vs "自由粒子玻尔兹曼分布 etc, not really organized) making "量子態相互作用" possible;
3.
so what is point or where is money? or "implications"? what & where is the "apps" for me and now?
量子 computer in macroscopic environment/heat bath (like room temperature and massive of whatever) in real life/large production is really hard, if ever possible;
"witten1 原创】量子生物学 I 摘要和前言 ( 复:91 ↑69 ↓0
这是前几天在Nature Physics看到是一篇有趣综述，现在寒假时间，尝试翻译一下以作为科普", kind of an example of bio system's real quantum working in macroscopic heat bath, and how to model it, etc.
so, fundamentally, AI challenge is not a math issue, it is a physics issue; without real breaking through in physics, software based computing like AI/大數據 stuff are not really going anywhere;
as I wroted before, we still don't even have a real model for quantum 生物大分子 computing, which is so far limited to a couple of thousands atoms working together, where in gene or protein we have millions if not zillions atoms working together;
one road block is how to model the strong if not full interaction between those atoms or 分子, so far physics can only handle quantized interaction or linearized/renormalized interaction, or "simplified" interaction, roughly speacking; but that kind of interaction is not real interaction anymore, humanity needs 爱因斯坦 or his type.
quantum chemistry 's monte carlo simulation etc (basically 大數據) has been going on for years, still limited by computing capacity as said, and fundamentally, limited by the lack of a theoretical model in handling a strong/non-linear interactions.
before breaking through in quantum chemistry and quantum computer, as I wrote before, we are basically eating GMO/基因 food stuff, with an experience based/very rough model only, taking unknown risk, unhedged, how can you hedge something unknown?
for quantum chemistry, even the "simplified" interaction" is difficult when simulating millions atom/分子 working together, future quantum computer may help that, still, we need a strong/or full interaction model to handle 阶级斗争 stuff at brain atom/分子 level, as good as TG does, at least, or TG senior folks will still have their best jobs in the world(:).

http://www.ccthere.com/topic/3903480/2
strong or full interactions is one of 新的热庫, if we break into it, then we will have an gigantic progress in civilization, where "social science" 神职人员 like Chinese TG and US wall street will still have jobs, but getting paid much much less for their "BS" work.
kind of like today, because of global internet, 作家哲学家 still 忽悠 around, but getting paid much much less, a few of them still 忽悠 mass/ordinary people, but society as a whole is paying 作家哲学家 much less for their 忽悠;
5.
it has been for a while: Chinese TG and US wall street (excluding US political elite and google folks) somehow & for some known and unknown reasons, possibly because of "量子態相互作用" between them(:)(TG knows US WS always likes money, so buy them out), they have and will much more likely to work together to make big money and therefore to defend their jobs than otherwise, and they have been working together anyway in the past, planned or not planned, etc. of course, on other hand, google folks always try to break down the GFW of china, relentlessly.
Or one could argue that, as a strategy to survive and prosper, Chinese TG has been and will be carefully doing 统一战线 with US financial capital, to hedge against US political elite and google folks' long term strategic evil goal of breaking down Chinese TG into pieces, eventually.
with that model, Chinese TG's 2nd 淮海战役/城镇化 will and must work out with US capital's strong pariticipation, and both of them will make big money as usual, with money and china's GDP growth, TG can maintain its ruling elite status in china, and china somehow as a super global power, next 10 years, very likely.
and google will keep bring out new toys based on likely fake AI, until MIT folks figure out a real quantum computer for massive production, before that, china's GFW will be fairly solid. no worry for TG.
as I posted before, fundamentally, the best strategy for Chinese nation to fend off this eventual "white wolf offense" on Chinese nation (TG and Chinese nation some how are all mingled together, as a strategy of TG, TG=china) is to develop a 李光耀 连战 proposed 新加坡/TW/china mainland 邦聯, and with a global network of almost 100 million Chinese possessing white's science/technology etc, this great china encompassing pacific will be a nightmare to us/Europe political elite and google alike technology power. then, a real global game changer may come into play, OMG, white house in nightmare everyday, in and out of its war room.
But, TG already fxxked 李光耀/连战 day dream, TG's red Gen I&II doesn't want to share power with other Chinese elite, period. never. and that window of opportunity has likely been closed on TG already now.
and I would think, that uncle sam's political elite will work even harder to make sure that "window" is closed forever. It is the super #1 priority for every US president going forward.
6.
still, after all these stuff, I would think that a much more diversified ccthere.com as it used to be will benefit everybody, including those TG 党小组 folks (many overseas volunteers) here, new stuff/new brain food from ccthere.com will help them expand their knowledge and to get promoted, while doing 熱輻射 (治大国如烹小鲜, maximizing brain entropy of Chinese folks, kind of, 意识形态战役, if 赢不了, messing it up, my guess of X'意识形态战役 model ) work for TG, better to keep your own brain from maximizing entropy, this is good for you, I really mean it, not to offend anybody, which is meaning less in this anonymous public forum, aside from TG's ccthere project goal(:).

科学 = 逻辑 + 实证 [ Solitude ]
前者主要指分析（演绎）逻辑，也就是假设，推理，结论，blabla...这个东西主要起源于古希腊的苏格拉底，柏拉图，亚里士多德，最早最有名的产品就是欧几里德的几何原本了。欧几里德本人就是柏拉图学园的学生。后者我想还是要感谢伽利略的启蒙吧，就不多说了。
科学当然也需要归纳逻辑（白米，黑米，红米都能吃，所以所有的米都能吃）的帮助。其实任何人都离不开归纳逻辑，否则会饿死的（罗素语）。但是依赖归纳逻辑的科学是不严谨的，最终还是要靠分析逻辑"
"歸納法是採用「由部分累積到整全」的研究途徑，而演繹法則是「由已知部分透過邏輯推知未知部分」的研究途徑"
I wrote in the past about 彭恒武 commenting on "愛因斯坦两句話", but can't find the link. basically, 愛因斯坦 分析逻辑/演繹法則 model helped humanity discovered atom/分子, with his 理論模型 (basically statistical physics/波爾茨曼 theory based modeling of 布朗運動 ) work on 布朗運動, and his 光电效应 pioneered quantum physics, and without those two breaking through, where humanity would have been today? likely we will be all toiling somewhere in a coal mine etc, supervised by a bounce of 政治委员/政治部主任, globally.
and 愛因斯坦 分析逻辑/演繹法則 model on atom/分子 is a non 简并 model("自由粒子玻尔兹曼分布"), later, he and 玻色 worked out 玻色－爱因斯坦统计, the 简并 version (it has a 自由粒子 version as well), which is still one of the fundamental model quantum physics use today in working on 玻色－愛因斯坦凝聚 type material & technology in those such as 量子效应 in 介觀物理/纳米, and we have not talked about 愛因斯坦's SR & GR yet. He is a great man.
by the way, 费米统计 is an another qm stat model, some us researchers already utilized that model in analyzing consumption pattern for mass consumers, such as movie renting, I posed it somewhere in that past.
now, social science, yes, it is "different" from physics, but without physics, social science will be still a science inside churches, with 政治委员/政治部主任 telling you about what 宇宙真理 looks like, we all know what that BS looks like;
can humanity afford losing "科学 = 逻辑 + 实证" as a 公知 model in physical science in particular and in humanity/society in general? what is risk? is TG china type 7% GDP growth worth the risk/cost of abandoning white's 公知 model for humanity? does humanity have any alternative model at all?
actually, even some white 公知 social scientists are bit of worried about brain science progress too, (charlierose.com). there is this very famous US 作家哲学家 recently talking about brain science breaking through vs white's traditional ideology myth/idols of thousand years. In the show, this super famous 作家 asks, if computer can do all the thinking as our brain do, what about our "faith" systems? he can't imagine a world of that, thinking that would be as serious as the earth is hit by an earth shaking object from universe. I don't remember his name.
if nothing else, nobody would care about his half political half history and beautifully written 文学作品 anymore, but he said, he really worries about humanity as a whole in the face of this mind boggling quantum brain science potential break through.
8.
as I keep saying, Chinese TG and its model will work out in china for the foreseeable future, and it will benefit Chinese and global economy, but for god's sake, for your children, if you can afford it, have them study English and quantum physics, in US or Europe, and I hope I don't get anybody offended.
meanwhile, TG's 2nd 淮海战役/城镇化 will go on relentlessly and likely successfully, anyway, regardless, get it? and on the way, get some money into your accout (:), the way many TG senor traders do, why not!?

今天在arXiv上读到了一篇非常有趣的论文，由MIT的物理学家Max Tegmark撰写，名为《 Consciousnessas a State of Matter》(作为物质状态的意识）。他认为，自我意识可以认为是某种物质形态，如文中的表一所示，意识必须同时包含有长期存在的状态，集成化的信息，容易写入性，以及复杂的动力学。气体，液体，固体，乃至计算机都只能满足一部分判据。
index为了解释意识可以被看成是物质的一种形态，他提出了六条原理，见表二
火狐截图_2014-01-08T02-53-08.299Z
利用这些原理，他主要研究了”量子因子分解问题“，或者说作为一个有意识的的观察者，比如说我们，为什么可以感受特定的希尔伯特空间分解所对应的经典空 间，而不是傅里叶空间。或者更一般的，为什么我们把周围的世界理解为动态的层级，其中包含许多强烈集成且相对独立的物体。他认为，这个原理与所谓的从头开 始物理问题（physics-from-scratch）有关：我们如何才能从不过两个厄米矩阵中提取出三维空间和我们周围的半经典世界。能否仅从哈密顿 量H中提取出这些信息，而H完全可以仅从它的本征能谱来描述。
接下来，Max Tegmark详细的讨论了什么叫做Integration(整体性)。在他看来，我们的世界是分层次的客体。比如说，你正在喝一杯冰水，你会感受到在玻 璃杯中有冰块。玻璃和冰块是分立的客体，因为它们都各自是一个整体且相对独立，它们内部的联系远远比与外部的联系紧密。我们可以定义物体的稳定性为集成温 度（把整体分离为部分所需的能量密度）和独立性温度（在层级内把母辈物体分离开所需的能量密度）之比。比如说，冰块的独立温度大概是3毫开，集成温度大概 是300开，稳定性是10^5。在下一级的结构中，氧原子和氢原子的稳定性都是10。氧原子核的稳定性是10^5。稳定性越高，这个物体越容易被我们感知和定义。
他发现，利用纠错码，经典物理允许信息基本上完全地被集成。任意一个包含至少半个比特的信息的子系统就可从剩下的比特中重建出来。存储在Hopeld neural networks (Hopeld神经网络）中的信息是天然的可纠错的。但是10^11个 神经元只能支持大概37个比特的集成了的信息。这就带来了一个集成化的悖论：为什么在我们意识体验所包含的信息内容似乎远大于37个比特。更糟的是，他发 现把这个结果推广到量子信息领域，反而加重了集成性悖论：量子信息系统只能支持不多于四分之一集成化的比特。实际上，对于任意大的量子系统，无论我们如何 编码，它所包含的可集成的信息都不会超过四分之一个比特。这强烈的暗示我们，集成性原理至少需要一个附加的原理作为补充。
他接下来探讨了独立性原理，讨论了如何通过希尔伯特空间分解实现其对应的哈密顿量分立为互相独立的部分。他发现了量子芝诺效应悖论：如果我们把宇宙分为最 为相互独立的几个客体，那么所有的运动都会陷入中止。既然有意识的的观察者显然没有感受到任何的停滞，那么集成性和独立性原理必须还需要至少一个原理来作 为补充。
进一步的，他研究了动力学原理，因为有意识的系统不仅能存储信息，还要能处理它。他认为能量相干性（energy coherence）\delta H \equiv \sqrt{2\text{tr}\dot{\rho}^2} 可以作为动力学的合适度量，它与时间无关，且在某些纯态情况下约化为能量的不确定性\Delta H。把动力学最大化只会导致无聊的周期解，无法支撑复杂的信息处理。但是减小\Delta H到合适的值时，将出现混沌和复杂的动力学，能遍历希尔伯特空间的所有维度。他 发现高度的自主性（独立性和动力学原理的结合）即使在一个高度开放的系统中也是可以实现的。
由上可知，Max Tegmark并未解决量子分解问题，但是这些结果可以帮助人们聚焦问题，并能强调具体的公开子问题和从观察得来的各种暗示和线索 。他还提出了一些公开的问题：
1.因子分解和鸡与蛋的问题：量子态和分解哪个先哪个后？
2.因子分解和集成化悖论
3.因子分解和时间的浮现
正定矩阵怎么理解较好？

- 复 向你推荐这本书
家园 自然语言: 熱輻射, 腦殘 risk 1.
this is a good book, thanks, and I will read it.
"From Pythagoras's harmonic sequence to Einstein's theory of relativity, geometric models of position, proximity, ratio, and the underlying properties of physical space have provided us with powerful ideas and accurate scientific tools. Currently, similar geometric models are being applied to another type of space—the conceptual space of information and meaning, where the contributions of Pythagoras and Einstein are a part of the landscape itself. The rich geometry of conceptual space can be glimpsed, for instance, in internet documents: while the documents themselves define a structure of visual layouts and point-to-point links, search engines create an additional structure by matching keywords to nearby documents in a spatial arrangement of content. What the Geometry of Meaning provides is a much-needed exploration of computational techniques to represent meaning and of the conceptual spaces on which these representations are founded."
2.
remember "Erik Verlinde"? we talked about him and that young Harvard physics guy's AI app based on Verlinde model.
roughly speaking with a lot of analogies, 引力 is interaction force, but it is very hard to measure or quantize 引力 or 引力量子化 in more physics oriented terminology. 引力质量和惯性质量相等, locally, you can't tell the difference between the two.
3.
what all these have to do with my brain?
as posted, human brain out of its survival and growth instinct in interacting with unknown heat bath("阶级斗争"強耦合 field) surrounding him, quantum brain has to perform this Feynman路径积分, again, this is the only model humanity understands in terms of QFT;
now, 引力质量和惯性质量相等 (an analogy, QFT excluding GR), locally, and I am locally all the time (vs us wall street and Chinese TG kind of organized global view/modeling), how my brain can do its job? it can't, then we get emotional, our expectations get hit by hard reality, broken brain, broken heart, omg, end of world, or a stone brain from here into a grave, as chairman mao said, he is a smart guy, he sees most people around him (such as vice chairman Liu(:))with actually stone brain.
4.
Erik Verlinde's 引力的熵力假说
4.1
why "阶级斗争"? why not united under chairman mao and we together fight heat bath (unknown challenges facing humanity in an analogy, such as what the heck is going on with 牛顿的水桶, which humanity still can't figure it out yet), then we all go into communist heaven world?
there is no chairman mao anymore, first of all;
secondly, humanity has come to some kind of consensus (more outside of china, and china is slowly catching up with white in terms of "logic gap") that we have to perform a civilized "阶级斗争" peacefully among ourselves in modeling this heat bath challenge, etc.
kind of like 牛顿的水桶:
水桶 is 轉動, but relative to what? relative to heat bath? then how to measure & model heat bath?
one way is to measure 水桶轉動 itself, and hopefully, we can derive 引力/heatbath via derivatives (2nd order modeling etc) of 水桶轉動
similarly
civilized "阶级斗争" peacefully among ourselves 逻辑实证證偽=basically the whites market system and 人權
政黨競爭,etc, a messy (in terms of its productivity and etc) 公知 model, vs china's 伟光正 model.
basically, it is a 牛顿水桶轉動 "game" in a social science setting, shall we as a humanity pick some 伟光正 group an judge of this entire humanity game of survival and growth?
that said, TG's model(no choice anyway) is likely to work out in china's gdp growth oriented economy, since it is basically 山寨 white from behind in almost every major area of its economy, a much easier challenge to handle.
in terms of Erik Verlinde's 引力的熵力假说, we have to come back to our 熱力熵力 model to gauge 引力 or new information.
4.2
the bloody cost of 熱輻射
in an analogy, human brain "神经元弹簧" struggles like a snake in this social 引力 field, for his or her survival and growth, as an individual (mostly unorganized, even in china, if you are not part of TG-centered elite, which is always a tiny minority), then most likely your "神经元弹簧" will be losing its battle vs heatbath 熱輻射, eventually stop working, giving up, go to a temple and work on 氣功 stuff;
and biologically, most people die this way anyway, in their short life on earth.
5.
without going into specifics of physics terms and models, what we can learn from Erik Verlinde's 引力的熵力假说 is actually very basic but very important, often very alarming:
自然语言: 熱輻射, 腦殘 risk, if not modelled well, and heat 传播 is super fast, soft 自然语言 can 爆 your ass (if lucky) and brain (very bad,omg), all legal to the profit collectors or market makers.
and in TG's terms, 利用小说进行反党 是一大发明 鄭大你的眼睛, plain vanilla "logic", but often in a very twisted Chinese local settings, much more twisted than us wall street market place.
Erik Verlinde's 引力的熵力假说 is still a 假说, meaning it is only a 逻辑 model, there is no 实证 yet;
with that comes big smiling faces of us wall street, and Chinese TG: 利用小说进行反党 是一大发明 as a business still commands a fat profit margin, long way to go, just do it, why not? (:)
6.
with all that and in the "final" analysis, humanity as a system has to come back to its roots in
"科学 = 逻辑 + 实证"
http://www.ccthere.com/alist/3986059
科学 = 逻辑 + 实证 [ Solitude ]
前者主要指分析（演绎）逻辑，也就是假设，推理，结论，blabla...这个东西主要起源于古希腊的苏格拉底，柏拉图，亚里士多德，最早最有名的产品就是欧几里德的几何原本了。欧几里德本人就是柏拉图学园的学生。后者我想还是要感谢伽利略的启蒙吧，就不多说了。
科学当然也需要归纳逻辑（白米，黑米，红米都能吃，所以所有的米都能吃）的帮助。其实任何人都离不开归纳逻辑，否则会饿死的（罗素语）。但是依赖归纳逻辑的科学是不严谨的，最终还是要靠分析逻辑"
"歸納法是採用「由部分累積到整全」的研究途徑，而演繹法則是「由已知部分透過邏輯推知未知部分」的研究途徑"
again, can humanity afford going away from that model, in physical science in particular, in humanity and society in general?
there is no alternative yet.
7.
the beautify of Feynman 路徑積分 again
"经典的状态其实对应的是量子态空间的一组基, 量子事件通常被说成是在这些点处插入顶点算子，这些顶点算子诱导了量子场的激发和退激，物理上要考虑这些量子事件的关联，也就是说这些事件背后有没有什么物理的或者动力学的原因"
again, in an analogy, 顶点算子 in a dissipative system (耗散系统, physics can't handle that yet) could be even more dramatic in terms of its impact on the system itself, think about 愛因斯坦 and 希特勒 as some kind of 量子事件/顶点算子 on the border of an otherwise fairly classical human system;
and I would think that humanity system now is solid enough to prevent 希特勒 kind of 顶点算子 to come to power and to change the path of humanity as a whole;
but, we don't really have a system to produce 愛因斯坦 type 顶点算子 yet;
this is kind of physics of white's 天賦人權 model: other than humanity reasons, there may be physics reason as well: we expect your child to out perform in whatever field fitting him/her, let her fly and shine, it will benefit all of us, eventually, including your small Chinese family organization.
we hope him or her to be an 愛因斯坦 type 顶点算子 to help humanity move forward.
that is why I said a couple of times here. if possible, let your children start studying English and quantum physics, starting yesterday, better in US or Europe, period, get it, baby?(:)

很多人可能都听过这个故事：牛顿在苹果树下正在聚精会神的思考，突然一个苹果砸到他头上，他茅塞顿开，发现了引力。但是长期以来，物理学家也知道引力很奇怪，和其它基本相互作用力相比，引力处理起来非常困难。现在原因可能已经找到：引力不是一种基本相互作用力，而是一种类似橡皮的弹力一样的衍生力。
据纽约时报2010年7月12日报导，阿姆斯特丹大学理论物理学院埃里克.弗林德教授（Erik Verlinde）提出引力新理论，认为引力不过是物理学中热力学定律的必然结果。
弗林德教授这样阐明自己的观点时说：“对我来说，引力不存在。”这并不是说他不会跌倒，但弗林德博士和其他一些物理学家认为，科学一直在以错误的方式看待引力。有一些更基本的规律导致了引力的出现，就像股市规律是一个个投资者行为的集体表现，或者弹力产生于大量原子的力学行为。
理论的核心和系统无序程度——熵有关。就象人的头发在湿热的环境下会卷曲，因为头发卷曲比伸直有更多的组态，而自然喜欢更多的选择。要想把头发拉直从而消除卷曲，需要力。忘掉弯曲的空间或牛顿引力，我们称之为引力的力量只不过是一种自然倾向——无序最大化的副产品。
弗林德教授的理论认为引力从本质上是一种熵力，如果一个物体在其它物体周围发生微小移动会改变周围的无序度，就会感受到引力。在这个想法的基础上加上全息理论的假设，他可以推导出力学中的牛顿第二定律。另外他的理论对物理中的惯性质量也有了新的认识。
弗林德教授的理论在物理学家中激起了强烈的反响。哈佛大学弦论学家安德鲁.斯特罗明格(Andrew Strominger)说：“有些人说这不可能是正确的，其他人则认为这是对的，我们已经知道它---它正确而深刻，正确而平凡。”“你不得不承认，”他接着说，“它启发了很多有趣的讨论。这是一个很有趣的想法集合，它点到了宇宙中我们最不了解的事情。这就是为什么我喜欢它。”
弗林德教授说在纽约石溪大学访问时，有人跟他说围绕着引力展开的故事就象皇帝的新衣一样。“我们知道引力不存在已经很长时间了，”弗林德博士说，“现在是到了大声喊出来的时候了。”
现代科学对宇宙的研究基本上是以现在的引力理论为基础。如果引力不存在，那么目前科学对星系、宇宙结构的认识必然是错误的，这可能是天文学家常常发现引力难以解释遥远天体的运动而不得不引入“暗物质”的原因。新的引力理论或许会激发科学家们寻求对宇宙全新的认识。
家园 熊起:人脑没有内外态区别,存储是树状增量并行,非线性寻址 http://www.ccthere.com/alist/3847181
熊起
后文会提到预期的重要性，接收信号，是尝试各种已有的“预期模式”，和接近感官的区域进行匹配尝试，选择出最接近的模式。以视觉举例，人脑并不具有数码相机那样输入点阵的能力，必须在中间环节就完成提炼
人脑没有内外态区别，没有运算器，只有单一存储功能。人脑存储是树状增量并行，不是线性寻址。在固定数量神经元组合下，恐怕量变就是质变，可以描述的结构不同了。
说的比较简单的是《皇帝新脑》里的一进制图灵机，讲哥德尔机的大多也会讲到。图灵机概念上是一个运行在无限纸带上的状态机，纸带是外存储器也是输入输出媒介，图灵机拥有内态，纸带上的输入信息可以影响内态，根据内态不同会改变对纸带的输出行为，状态到操作纸带的映射就是数字到运算的映射。
图灵机作为表达算法概念的工具，一开始就有明确的输入输出接口。人脑则不同，神经元只有应激和保留应激的功能，所有运算都以查找完成，查找是并行进行的，查找时并行数随着步骤增加而增加。这方面《人工智能的未来》讲的比较明白。
---------
进化没有一个宏观的远大目标，人脑是补丁叠补丁，新脑套旧脑，暂且放下对精美宏大理论的渴求，有助于对一个个问题各自理解。

human brain is almost like 費曼路徑積分, trying gathering information globally while interacting with SR heatbath/強耦合場, historically as well as future forward looking,half half, in picking a logical path for actions, kind of, with huge potential for both achievments and erros, particularly for "unorganized" individual;
1.
aritificially limiting a human brain potential of any individual is almost like depriving a child of its education, very brutal in the eyes of whites (of course, whites first, an "advanced" class)this is kind of physics part of white 人權 concept: can you tell your children not to go to college, because you children have to think and work in the interest of family organization, whatever that interest may be?
2.
information in a SR heathbath can only be processed by "洛伦兹变换" and its 檢驗, to "prove" its "trueness and objectivity" (yes, we have qm subjectivity);
ideology as some kind of 玻色子 has energy, therefore subjecting itself to SR "洛伦兹变换" and its 檢驗, in social science case, it is basically playing out in the white's market system and 政党政治 political drama, yes, they are all very often primitive and ineffective as a "social science";
3.
in contrast, TG's social science is basically 先验论 & 隐參數模型 (I wrote about it before): TG must be right, TG will always be right, regardless, the traditional tricks of Chinese political elite for 5k years, "天寿" or empowered by Chinese GOD, and chinese people largely buys it, and chairman X wants to make sure TG's people will stay that way, respecting and accepting TG's leadership almost unconditionally. regardless of money and sex privilege stuff, what is the core logic and concept of TG's model, can chairman X articulate it out, other than a bounce of political and emotion invoking slogans?
3.
I think that fundamentally TGs' top knows their weakness in many areas, and the US white wolf eye have been always staring at them, that is why TG has to 统一战线 with US financial capital, pushing this 2nd 淮海战役城镇化 at whatever cost, preparing for the worst, never say never, bad thing can actually happen, even as a small probability event to start with, and that is one of the key concepts of 費曼路徑積分. TG is very smart, and very experienced too. so are many TG senior traders, in wresting with uncle sam in next 10-20 years.
It will be a lot of fun, and watch out for yourself, baby(:).
