Learning and Tree Search in a previous paper to go from scratch, no human reconciliation data is used during training. Near the end of the year, we saw a new generation of AlphaGo: AlphaZero. After go, we used the same technology to play chess and Japanese games. The strategies used by these algorithms in the game are sometimes surprising to experienced players

Cocos2d-x 3.1.1 Learning Log 16--A Star Algorithm (A * search algorithm) Learning A * search algorithm is commonly known as the astar algorithm. This is an algorithm with multiple node paths on the graphic plane to find the lowest cost. It is often used in the mobile computi

This is the definition of geometric spacing .You can see that the geometry interval and the function interval are very similar, but the distance from the point to the plane does not change because of the w,b , and at this point, the geometric interval is more meaningful and valuable than the func

The square in the figure is the position of the non-leaf node, the position of the @ leaf node, so the length of a table should be: 1/plotTree.totalW , but the position of the leaf

SummaryClustering is unsupervised learning ( unsupervised learning does not rely on pre-defined classes or training instances with class tags), it classifies similar objects into the same cluster, it is observational learning, rather than example-based learning, which is somewhat like

In the introduction of recommendation system, we give the general framework of recommendation system. Obviously, the recommendation method is the most core and key part of the whole recommendation system, which determines the performance of the recommended system to a large extent. At present, the main recommended methods include: Based on content recommendation, collaborative filtering recommendation, recommendation based on association rules, based

So give a new point, how to tell if it belongs to the blue category or the red one?The answer is to ask for distance. (in the classic case seems to be

Ajax has come to an end, all the foundation has been, there will not be too much problem. on the premise of not having to learn Ajax directly, like "on top of the floating sand", so, the Ajax learning sequence is arranged here. nineth Step learning Ria Technology Ria:rich Internet application can be regarded as the attempt to combine C/s and b/a advant

public. Of course, there is a good advantage to compressing large values into this range, which is to eliminate the effects of particularly conspicuous variables (not knowing if they are correct). The realization of this great function in fact only needs a trivial one, that is, in the output plus a logistic function. In addition, for the two classification, it i

The KNN algorithm is simply said to be "birds of a Feather", that is, the new classification is not classified as the surrounding points of the majority of the class. It is classified by measuring the distance between different eigenvalues, and the idea is simple: if the K-points in the feature space of a sample are closest to one class (Euclidean

Build a blog, enlighten others or discuss ideas with friends. 7 to organize your blog subscriptionsSome forms of learning are easy to digest, but often lack substance. I often regularly clean up my subscribed blogs. A great blog is a
