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

When we call qapplication: exec (), QT starts the event loop. At startup, QT issues a display and draw event to display the control. Then, the event loop starts, constantly checks whether an event occurs, and then assigns the event to the qobject

After reading a lot of KMP Algorithms on the internet, I always feel confused. Finally, I learned about the KMP algorithm by turning over the data structure of Wei Min. Here we will share with you. For those who haven't touched the algorithm for a

There are 22 bad tastes in refactoring. I will explain them one by one. Wait !!! You made a mistake !!!   80% principle: Our 20% Code only violates the bad taste of 20%, so we only need to learn the and do it well, then you are a good programmer.   "

    This chapter provides a guide for designing mapreduce algorithms. In particular, we show a lot of design patterns to solve common problems. In general, they are:   "In-mapper combining" (merge in map), The combiner function is moved to Mapper,

0. Why model-free learning?PS: The value of the iteration in the course is the value function; Zhou Zhihua Teacher's watermelon book is the state value function; The state-action value function is iterated in the course.1. Monte Carlo method: Sum

3.3 calculation relative frequency   Let's talk about pairs and stripes.AlgorithmAnd then build a reproduction matrix m on a large dataset. Recall that in this large n × n matrix, when n = | v | (Dictionary size), the element mij contains the

A lot of the previous articles were about distributed storage, and the next chapters went into the field of distributed Computing. Frankly speaking, the personal focus of the previous professional focus on storage, the content of many calculations

Ubuntu PHP takes up a lot of resources ------to solve the idea---------------------- This is the case in itself, so when using PHP, you should pay attention to the problem of process occupancy. ------to solve the idea---------------------- You're

A solution that phpexcel large files with large memory consumption Phpexcel because it is a memory processing mechanism, when the number of rows or columns of Excel file memory will be an instant hundreds of m, due to server reasons I can not

1, value based method/policy based method meritsThe student points out: Because value based needs more storageSilver:why?Silver: (self-answer) because the strategy value ratio function is more efficientPPT Summary:Advantage:Better Convergence

With the popularity of WiFi, all kinds of smart devices at home are connected to WiFi hotspots and surf the web. However, as the leader of a home network, we must know how to manage speed, for example, through routers to see how many devices are

1. Foreword The VRRP (Virtual Router redundancy Protocol) protocol is a protocol for implementing router redundancy, the latest protocol is defined in RFC3768, the original definition RFC2338 is abolished, and the new protocol simplifies some

The same computer and software, only the system is different, if you have compared to you will find. The function of the system occupies a large amount of memory. This is because the system has many functions that XP does not have, regardless of the

First, some concepts Markov properties: The current moment state is only related to the previous moment. The state transition matrix shows the conditional probability of arbitrary state A to State B. Markov process (Markov chain): A Markov-type

Phenomenon: Web site access is getting slower, finally inaccessible, after the check found that the disk is full Analysis Process and solution: Usually this problem should be logged on to the server to check the disk, memory and process use, through
