MIT的neural network课程和computational neuroscience课程
的全部录像和课堂资料,我花了好多时间看了一些,觉得非常好
Seung是computation neural方面的大牛,HHMI的Member,
在neural computation方面的HHMI好像只有他和Salk的

Seung讲课深入浅出,看他的课程movie的感觉好像看有趣的电视连续剧
里面还有computational Bio的录像,大家找找就能找到download的地方

this Nature paper (2002 417:39) addressed the mechanisms that
control fate of neural stem cells. astrocytes have been
thought merely as supportive cells in the central nervous
system, however, this work has demonstrated that astrocytes
isolated from adult hippocampus, but not spinal chord,
promoted neurogenesis (i.e., neuron fate) of the adult neural
stem cells in cell culture. this study has highlighted the
effects of the environment on the specification of stem cells.

Neural bases for addictive properties of benzodiazepines p769
Benzodiazepines, such as valium, are used both in clinics and for
recreational purposes, but lead to addiction in some individuals. Addictive
drugs increase the levels of dopamine and trigger synaptic adaptations in
the mesolimbic reward system, but the neural basis for the addictive nature
of benzodiazepines remains elusive. Here, they are shown to increase firing
of dopamine neurons in the ventral tegmental area through GABAA recept

来自主题: DataSciences版 - Neural Network面试的时候会怎么问啊?
从来没有用过neural network. 我看了一下back propagation算法,好像就是用chain
rule从后向前算gradient,每一个neuron的 的参数的gradient重用用下一个neuron的
gradient的结果。对不对?
还有什么会问的?这个玩意我感觉很神秘,比如选择多少hidden layer, 每层hidden
layer 选择多少neuron,这些是不是都根据经验来?会问到这方面的问题吗?
实际工作中,neural network目前一般用来干嘛啊?手写识别?

答案我也不怎么清楚。但是我觉得问这些问题可以区分出来一个人是不是真正用过
neural network还是只是在书上读过。用过的人可能会说这个问题我们做什么什么的时
候碰到过,是这么解决的,或者这个问题解决不了,最后neural network不干活。

我说的是“基本”是数字的。神经元最基本的工作方式,就是产生动作电位,并把它传
到下面一个神经元。动作电位本身是没有大小概念的,其实就是数字的,0和1。
动作电位本身是研究得非常清楚的。但这些神经数字脉冲(spikes)是如何编码的,现在
还没研究清楚。我以前上过一门Neural Computation的研究生课,成天就是看各种对此
的假设和研究文章,一大堆公式,各种synchrony啥的,作业全是数学证明和计算,所
以上完课啥也没记住。开课的是索南,科大少年班拿李政道物理奖金出国的,最后还是

一个神经元接受很多其他神经元的输入,通过还不太清楚的很复杂的过程,决定是否产
生动作电位。这个复杂的过程,一般在工业界模拟起来,就简化为一个积分器的机制。
这其实就是IBM现在出品的那种神经芯片的工作原理,其好处是能耗很小,实现某一些
ML算法很容易。坏处是编程方式不是von neumann的,更像用模拟电路来编程。

之前几年或者多年,我在本版聊过几点浅见。
一是universal turing machine
我抽屉里有一本2000年买的本科生教材。计算理论基础。harry R Lewis写的。5。2节
第一段:
"
In other words, we shall be thinking of the formalism of Turing machines as
a programming language,
in which we can write programs. Programs written in this language can then
be interpreted by a
universal Turing machine----that is to say, another program in the same
language.
"
二是这个trick在什么地方?
Self Interpret的技术在Kenneth Thompson的图灵奖lecture有一段描述。
这个讲座以前我引用过.
其实就是C语言的\n 和 \ \n .

of course, you can call any functional and anatomical neural unit as a "
circuit", there's no strict definition of this term. And no need to care
that.
Actually, even as the example you give, it's not as linear as you think,
when 运动神经元形成一个躲避动作, it's actually a series of feedback signal
sent back to 神经中枢处理器, so there are a lot of "loops" here.
talking about 直线式 or not 直线式, doesn't make much meaning here.
