内容简介

　　强化学习（RL）的新发展结合深度学习（DL），在训练代理以类似人的方式解决复杂问题方面取得了未有的进步。Google使用算法在著名的Atari街机游戏中获胜将该领域推至高峰，研究人员也在源源不断地产生新的想法。《深度强化学习实践（影印版英文版）》介绍了RL的基础知识，为你提供了编写智能学习代理所需的原理，以承担一系列艰巨的实际任务。让你了解如何在“网格世界”环境中实现Q-learning，教你的代理购买和交易股票，发现自然语言模型如何推动了聊天机器人的火爆。

作者简介

　　Maxim Lapan，is a deep learning enthusiast and independent researcher. His background and 15 years' work expertise as a software developer and a systems architect lays from low-level Linux kernel driver development to performance optimization and design of distributed applications working on thousands of servers. With vast work experiences in big data，Machine Learning， and large parallel distributed HPC and nonHPC systems， he has a talent to explain a gist of complicated things in simple words and vivid examples.His current areas of interest lie in practical applications of Deep Learning， such as Deep Natural Language Processing and Deep Reinforcement Learning.Maxim lives in Moscow， Russian Federation， with his family， and he works for an Israeli start-up as a Senior NLP developer.
