程序源代码： Question: Determine how many prime numbers are between 101-200 and output all prime numbers. Program analysis: the method to determine prime number: use a number to divide 2 to sqrt (this number). If it can be divided by an integer, it indicates that this number is n...
协议:CC BY-NC-SA 4.0 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...
