一、机器学习和深度学习简介 深度学习的主题最近非常受欢迎,在这个过程中,出现了几个术语,使区分它们变得相当复杂。人们可能会发现,由于主题之间大量的重叠,将每个领域整齐地分开是一项艰巨的任务。 本章通过讨论深度学习的历史背景以及该领域如何演变成今天的形式来介绍深度学习的主题。稍后,我们将通过简要介绍基础主题来...

Many processes in nature involve randomness in one form or another. 自然界中的许多过程都以这样或那样的形式涉及随机性。 Whether we investigate the motions of microscopic molecules or study the popularity of electoral candidates,we see randomness, or at least apparent randomness, almost everywhere. 无...

The following illustrates calling a Python method (here called from_java()) from Java. In the example there is one argument which is a string. Java sees the method as having a different name, in this case callback_string().The technique relies on passing the method inside a wrapper class...
If this returns true, it is still possible that a call fails, but if it is false, calling object will never succeed. Note that classes are callable (calling a class returns a new instance); instances are callable if their class has a __call__() method. ...
