Deep Learning.ai学习笔记_第二门课_改善深层神经网络:超参数调试、正则化以及优化

/目录第一周(深度学习的实践层面)第二周(优化算法)第三周(超参数调试、Batch正则化和程序框架) 目标:如何有效运作神经网络,内容涉及超参数调优,如何构建数据,以及如何确保优化算法快速运行,从而使学习算法在合理时间内完成自我学习。如何选取一个神经网络的训练集、验证集和测试集呢?如果数据量比较少,例如只有1...

Deep Learning.ai学习笔记_第三门课_结构化机器学习项目

/目录第一周机器学习策略(1)第二周机器学习策略(2) 目标:学习一些机器学习优化改进策略,使得搭建的学习模型能够朝着最有希望的方向前进。搭建机器学习系统的挑战:尝试和改变的东西太多,比如超参数。 什么是正交化?正交化是协助调节搭建机器学习系统的方法之一,类比老式电视机的调节按钮,正交化指的是电视设...
