    现在的深度学习过程是一个计算密集的过程。

    然后就是深度学习理论很难也暂时没有很完美的数学解释,从2006年开始复苏,才过去十年。

    现在的理论解释很多是用类比的方法,很直觉。举个例子,dropout的论文里引用了一段生物学的知识,说的是有性生殖,lecun同学为了解释深度学习不需要顾虑局部最小的问题,因为存在的概率很小,小到可以忽略,用的方法是公式大变形,将深度学习的公式换了个形式,同时加了几个可能不太严格的条件,然后就可以用玻璃的统计物理学解释来讨论问题了!

    这两个系统会互相学习,但是现在看来,用spark来做深度学习训练有点效率不太好

    window下咋安装呢 用docker安装不上啊 翻墙也不行

    错误如下:

    哪位能帮我看看嘛
