Old Borland users who use the BDN (Borland Developer Network) will be familiar with this kind of respect: This bearded man is David intersimone, vice president of Borland's developer community. Because intersimone is not easy to remember, the Community is used to calling him "David I ". In BDN, his photo was displayed on the homepage, and he introduced new Community content some time later. Bnd is an impor

This is the summary note of the first lesson of David Silver's intensive learning public class. The first lesson mainly explains the embodiment of reinforcement learning in many fields, mainly solves what problem, differs from supervised learning algorithm, which part of complete algorithm flow consists of, and what content the agent contains, and explains some concepts involved in reinforcement learning.

(Translator's note: At railsconf July this year held in February 2006, David Heinemeier Hasson gave a keynote speech about the rest design in rails 1.2, and the rest style brings about innovations in Web application design. The first time I saw this video, I thought it could be a historical presentation on Web server development. At that time, I listened to the speech and translated the speech into nearly 3000 words, which accounted for about 1/4 of t

Big tea today tells us about the recursion of C language and the call of functions. You can create the source file of functions in other files and call them in the main file, you can save on multiple lines of code in the main function. Once a program fails, debugging is very convenient. You do not need to find some small errors in a large segment of code. Recursive statements are similar to loops and have judgment statements. When the judgment statement is not true, the conditions of the judgme

. Data Segment Initialize data segments (global variables, static variables) Non-initialized Data Segment The initialization data segment needs to be defined by ourselves, and should be substituted into it before running. Non-initialized data segments are entered by the system when the program is running. 3. Stack is allocated by the system itself Data is first-in-first-out (or later-in-first-out) A. Local Variables B. Return address for function calling C. Information about the called Envir

This article is David MacKay 's use of information theory to compare performance differences caused by the essential differences in the fast and stacked rows.Information theory is very powerful, it is not just a tool to analyze the optimal decision of theory.It is very interesting to analyze the efficiency of the algorithm from the angle of information theory, which gives us a new way of thinking about the algorithm of sorting.Using the concept of inf

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 characteristicsValid in high-dimensional or continuous action spaceCan learn stochastic strategiesDisadvantage:Convergence to local optimality rather than global optimizationThe policy estimate is invalid?? and high-contrast2. Solving method of optimization

Panel development is the most popular agile and lean Development Method in recent years. David J. Anderson, the father of Kanban, believes that its core is to help enterprises create a capability-to improve agility. The CTO club panel training class will explain the core theory of Panel through theory, Sandbox simulation, and real case sharing. The Kanban method was born around 2006 and has become the most popular and fastest-growing agile method in r

The famous magician david copophil liked to perform the following magic: a matrix of N rows and n columns of different pictures appeared on the big screen. We named all the pictures as follows: Each participating audience was asked to put their fingers on the picture on the top left (that is, the picture numbered 1). The magician started: the Magician told the audience to move K times on the image (move the finger to the top, bottom, left, and right
