From AlphaGo to autonomous cars, we can find intensive learning in many of the most advanced AI applications. This technology is how to start from scratch to learn to complete the task, the growth of "beyond the human level" of experts. This article will be a brief introduction.
Neural networks have created recent breakthroughs in areas such as comp
As we all know, when Alphago defeated the world go champion Li Shishi, the whole industry is excited, more and more scholars realize that reinforcement learning is a very exciting in the field of artificial intelligence. Here I will share my intensive learning and learning notes. The basic concept of

This paper is the most important content in the book "Reinforcement Learning:an Introduction", which aims to introduce the basic concept and principle of learning reinforcement learning, so that readers can realize the newest model as soon as possible. After all, f
Introduction
The previous one is about Monte Carlo's reinforcement learning method, Monte Carlo reinforcement Learning algorithm overcomes the difficulty of model unknown to strategy estimation by considering the sampling trajectory, but the Monte Carlo method has the disadvantage that it is necessary to update the st
Preface
For the time being, many of the methods in deep reinforcement learning are based on the previous enhanced learning algorithm, where the value function or policy Function policy functions are implemented with the substitution of deep neural networks. Therefore, this paper attempts to summarize the classical algorithm in

In reinforcement Learning (iii) using dynamic programming (DP), we discuss the method of solving the problem of reinforcement learning prediction and control problem by dynamic programming. However, since dynamic programming requires the value of a state to be updated each time, it goes back to all possible subsequent
1 PrefaceIn the previous article, we introduced the two basic algorithms of policy iteration and value iteration based on the Bellman equation, but these two algorithms are actually difficult to apply directly, because the two algorithms are still biased to the idealized one. You need to know the state transition probability, and you need to traverse all the states. For the traversal state, of course, we can not do a full traversal, but only as far as possible through the exploration to the vari

Reinforcement LearningThe solution to the problem of control decision: to design a return function (reward functions), if the learning agent (such as the above four-legged robot, chess AI program) in the decision of a step, to obtain a better result, Then we give the agent some return (such as the return function result is positive), get poor results, then the return function is negative. For example, a qua
Deep reinforcement learning with Double q-learningGoogle DeepMind AbstractThe mainstream q-learning algorithm is too high to estimate the action value under certain conditions. In fact, it was not known whether such overestimation was common, detrimental to performance, and whether it could be organized from the main body. This article answers the above question
