to manually test these examples, to see whether the performance is poor or good, then it is difficult for you to make a decision. Whether or not to use stemming, is case-sensitive. But with a quantitative numerical evaluation, you can look at this number, whether the error is getting bigger or smaller. You can quickly practice your new ideas through it, and it's basically very intuitive to tell you that your idea is to improve the performance of the

Part I: ClassificationThe first two parts of the book focus on supervised Learning (supervisedieaming). In the process of supervising learning, we only need to give the input sample set , and the machine can push the possible results of the specified target variable from it. Supervised learning is relatively simple, an

Concept Learning and inductive bias
I feel that concept learning is rarely mentioned now, probably because it is rarely used in practical applications of machine learning, but it is easy to introduce the concept of inductive bias from concept learning

The 2nd Chapter Perception MachineThe Perceptron is a linear classification model of class Two classification, whose input is the characteristic vector of an instance, and the perceptual machine corresponds to the separation of the examples into positive and negative two classes in the input space (feature space), which belongs to the discriminant model. A loss function is introduced based on the error clas

What is machine learning? The answer to this question can be referred to the authoritative definition of machine learning, but in fact, machine learning is defined by the problems it solves. Therefore, the best way to understand

Lesson 1 Online Learning
Online learning refers to learning an optimal prediction function whenever a data is generated. The optimal criterion is that the value of the loss function at the current position is the minimum, therefore, the prediction functions in each step may be different. This is online
