The previous blog introduced OpenAI Gym, OpenAI Gym and intensive learning as well as OpenAI Gym installation, and then run a demo to experience OpenAI

Observation (observations) The previous blog introduced the use of OpenAI Gym's cartpole (inverted pendulum) demo, if you want to do in each step better than taking random action, then the actual understanding of the impact of action on the environment may be good.The step function of the environment returns the required information, and the step function returns four values observation, reward, done, info, and here is the specific information: Obser

Before actually starting to train the bot, the research team did a lot of preparatory work:For example, maximizing the use of CPU and GPU to speed up large-scale training, time is money, OpenAI finally used the 128,000 CPU core and 256 GPU to support the calculation, so that the AI every day to play tens of thousands of game games, da

ObjectiveOpenAI is an AI company founded at the end of 2015, led by Elon Musk, claimed to have a 1 billion-dollar investment, composed of several top players in artificial intelligence. This basically means a new DeepMind company was born, but this time the OpenAI is an organization that does not belong to any company.Why do you want to know OpenAI?Because OpenAI's research largely represents the research d

Do you know DeepMind?Probably know, after all, that the company has had two major events in recent years:1. By Google acquisition2. Spent a lot of resources to teach the computer Weiqi, and beat the current all known go top players Then you probably know that DeepMind in 13 sent a paper called "Playing Atari with Deep reinforcement Learning". This paper is about how DeepMind teaches computers to play Atari games. But what you may not know is why DeepMind to teach computers to play games. Well, y

Test Instructions: given an n, let you split it into the sum of a number of only 2 and 3, and there is no multiple relationship between 22, such as 10=4+6.idea: that is, the power of the 2 factor is incremented, the power of the 3 factor decreases, or vice versa.For the current n, we split the number to num=2^x*3^y; meet 2^x| N, and Y Max, and then continue splitting the n-num. Not difficult to launch, N-num is an even, and contains at least x+1 2 of the product, then the power of the N-num 2

Ask how many hours, every one hours can build an edge, can be multi-threaded build. Ideas: Drawing can find the law, the worst case is that n points is a linear, then the time will be the longest, according to the linear law found that its length and time is twice times the increment, each new hour can be on the
