In the previous article, the ID3 decision tree based on information gain was introduced. The basic decision tree concept and the computation of ID3 decision tree based on information gain are introduced in this paper. This article describes how to use Python to implement a ID3 decision tree, where the main code from the machine learning combat in the book, I made some changes to it, adding some content. pseudo code for the decision tree.
The decision tree can be generated using a recursive impl
Order of precedence between 4.1.6 operators
In the expression of some more complex conditional judgments, in the same expression, sometimes there may be multiple operators. For example, we judge whether to buy a watermelon, not only to determine its total price (8.2 yuan/catty, altogether 10.3 kilograms) is less than 100 yuan (because there is only so much money in the pocket), but also to determine whether the

When expressing complicated condition judgments, there may be multiple operators in the same expression. For example, when determining whether or not to buy a watermelon, we should not only determine its total price (unit price: 8.2 RMB/kg, total price: 10.3) whether it is le
Previously, a method of solving LR (linearregression), the norm equation (Normal equation), was discussed. This is the watermelon book on the method, which in Andrew Ng's public class also said a lot of other methods of solving parameters: Gradient descent (Gradient descent), which includes batch gradient descent (batch Gradient descent) and random gradient descent (Stochastic gradient descent).In addition, the probability interpretation of cost funct
Dog people see people eat dogs he can not accept, but for African refugees, you spend tens of thousands of dollars to keep a dog do not eat to play, you are evil.
Bathing is a huge waste of water for the desert dwellers, and it is a waste of food to put salt on the body, and to paint the face is a waste of means of production.

Linear can be divided intoFor a data set:If there is a hyper-planar x that can precisely divide the positive and negative samples in D into the sides of S, the hyper-plane is as follows:Then the data set D is linearly divided, otherwise, it is not possible to be divided.W is called the normal vector, which determines the direction of the super plane, and B is the displacement amount, which determines the distance between the super plane and the origin point.The distance from any point in the

I have been involved in the recent Q A games, and some questions are really difficult to answer, but 10 seconds is not enough for Baidu, so I wrote a secondary ticket, in this way, when a question occurs, Baidu automatically takes 2 seconds. The remaining 7 or 8 seconds can be analyzed and answered, improving the probability of winning.
