It is a very important numerical calculation method guided by probability statistics theory. A random number (or a more common pseudo-random number) is used to solve many computing problems. A Calculation Method Based on the Theory and Method of probability and statistics. It associates the problem solved with a certain probability model and uses an electronic computer for statistical simulation or sampling, to obtain the approximate solution of the problem, also known as the statistical simul

"Not completed" Monte Carlo Monte Carlo is a kind of general algorithm, the idea is to approach the real by random sampling, here only introduced in the reinforcement learning application.The initial idea should be to run multiple cycles in succession, such as after two times (s, a), and calculates the corresponding GT, then Q (s,a) to take the average on it, but in fact, in order to optimize the strategy o

Use Monte Carlo to simulate the ball π value. The Monte Carlo (Monte Carlo) method, also known as the random sampling or statistical test method, is a branch of computational mathematics, it was developed in the 1940s s to adapt to the development of the atomic energy industry at that time. The traditional empirical method is difficult to obtain satisfactory resu

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 states of that State. Results in a large amount of computation for complex problems. At the same time, we can not even know the environment of the state transformation model $p$, t

The first part: Introduction to Algorithms[1946:john von Neumann, Stan Ulam, and Nick Metropolis, all in the Los Alamos scientific Laboratory, cook up the Metropol is algorithm, also known as the Monte Carlo method.] John von Neumann,stan Ulam and Nick Metropolis, a three scientist at the National Laboratory of the United States in 1946, were invented as the Monte Carlo method. Its specific definition is: i

model of prior knowledge, at least according to the prior knowledge we can determine how much input can lead to how much output. For example play Atari this game, if the input only half of the screen, then we know that no matter how good the algorithm, can not be trained. Because the input is limited, and even humans cannot do it. But at the same time, humans do not need to know exactly what the exact model should be, and humans can deduce the results exactly according to the observations.There

First, what is the Markov chain Monte Carlo (MCMC) method? The shortest answer is: "MCMC is a method to approximate the posterior distribution of interested parameters by random sampling in probabilistic space." In this article, I can explain this short answer without any mathematical knowledge. Basic terminology of Bayesian theory system First, there are some terms. The parameters of interest are just some numbers that are used to abstract the

This paper introduces the basic principle and basic principle of using Monte Carlo method to simulate the BER. 1. IntroductionBER is an important index of performance evaluation of communication system, and the BER is a fixed value in a given channel and coding mode. In a few cases, the theoretical error rate can be obtained by theoretical deduction, but in most cases, the theory error rate cannot be pushed, so it is often considered that the
