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

Microsoft started the development of Interface Manager (Windows) in 1981, without the concept of a graphical user interface (GUI) or some of the features associated with Windows today.3. The menu for the Interface Manager's earlier version number is located at the bottom of the screen, similar to the current DOS version of Word and the user interface of some other p

Microsoft started Interface Manager (Windows) development as early as 1981. At that time, there was no graphical user Interface (GUI) concept, and some features associated with Windows were missing. 3. In earlier versions of Interface Manager, the menu is located at the bottom of the screen, which is similar to the Word of the current

Preface I am very honored to write the preface to this important task. On the basis of this, I will teach programmers the necessary skills to create the next generation of 3D video games. There aren't many books that teach you how to create a real-time 3D engine. At the beginning, pixels are drawn. From the original game of Atari to the present, technology has developed so far. We were really pushing the state of the art then, but they really seem lam

Introduction Speaking of the coolest branch of machine learning, deep learning and reinforcement Learning (hereinafter referred to as DL and RL). These two are not only in the actual application of the cool, in the machine learning theory also has a good performance. DeepMind staff and the essence of the two, in the Stella Simulator to allow the machine to play their own 7 Atari 2600 of the game, the result is playing out of the Americas, into the wo

do anything. when learning programming languages, consider yourself as a developer and systematically learn a variety of programming knowledge. the misunderstanding of automatic test learninga lot of beginners start by learning complex automated testing tools, I think this is putting the cart before the horse. If you do not understand the HTTP protocol first, you will not understand Jemeter, LoadRunner, Fiddler, soapui these tools. If you don't understand Html,dom first, you won't understand th
