再发：迄今为止脑网络结构功能模块元素最全面复杂清晰类芯片多图及分解

从工程的角度来看，大脑皮层是一个六层电路卡，由晶体管和逻辑门组成，其密度是我们最紧凑的微处理器（Apple A8）的五倍。然后它被智能折叠起来以适应更小的空间，同时还减少了相互连接的轴突的长度。大脑皮层的最小估计处理能力（基于突触等于晶体管）超过 34,500 个英特尔四核 i7 处理器，而实际上它甚至可能更高。

深度强化学习之：Policy Gradient Theorem 综述

Policy gradient 定理作为现代深度强化学习的基石，同时也是actor-critic的基础，重要性不言而喻。但是它的推导和理解不是那么浅显，不同的资料中又有着众多形式，不禁令人困惑。本篇文章MyEncyclopedia试图总结众多资料背后的一些相通的地方，并写下自己的一些学习理解心得。

Deep feature vae

此次介绍一下基于vae的一个经典改进DFC-VAE，所谓的dfc就是deep feature consistent，原文是这样说的“Instead of using pixel-by-pixel loss, we enforce deep feature consistency between the input and the output of a VAE, which ensures the VAE’s output to preserve the spatial correlation characteristics of the input, thus leading the output to have a more natural visual appearance and better perceptual quality. “

原则一书的管理干货

... 2) Realize that you have nothing to fear from truth. Understanding, accepting, and knowing how to effectively deal with reality are crucial for achieving success. Having truth on your side is extremely powerful. While the truth itself may be scary—you have a weakness, you have a deadly disease, etc.—knowing the truth will allow you to deal with your situation better. Being truthful, and letting others be truthful with you, allows you to explore your own thoughts and exposes you to the feedback that is essential for your learning. Being truthful is an extension of your freedom to be you; people who are one way on the inside and another on the outside become conflicted and often lose touch with their own values. It’s difficult for them to be happy, and almost impossible for them to be at their best. While the first-order effects of being radically truthful might not be desirable, the second- and third-order effects are great. ... 2) 你要知道，真相没什么可怕的。理解、接受、并了解如何能够有效处理现实问题，这对于取得成功而言至关重要。站在真相一边，就最有说服力。当然，有时真相本身可能会让人惧怕，比如，你暴露了一个弱点或者甚至是身患绝症，而了解真相却能让你更从容地处理事情。对自己坦诚、对他人坦诚，让别人也对自己坦诚，才能更好地了解自己的想法，获得他人的反馈，从而学到知识。诚实，同时也是做自己的自由的延伸。表里不一的人往往会自相矛盾，也容易丢失自己的价值观。他们不易开心，更不可能展现出自己最好的一面。尽管从一级效应的角度来看，过于诚实未免使人难以接受，但是从二、三级效应的角度而言，这样做却收效可观。
