two classification problem, so the model is modeled as Bernoulli distributionIn the case of a given Y, naive Bayes assumes that each word appears to be independent of each other, and that each word appears to be a two classification problem, that is, it is also modeled as a Bernoulli distribution.In the GDA model, it is assumed that we are still dealing with a two classification problem, and that the models are still modeled as Bernoulli distributions.In the case of a given y, the value of x is

under-fitting with verification curveValidating a curve is a very useful tool that can be used to improve the performance of a model because he can handle fit and under-fit problems.The verification curve and the learning curve are very similar, but the difference is that the accuracy rate of the model under different parameters is not the same as the accuracy of the different training set size:We get the validation curve for parameter C.Like the Lea

This article introduces several of the most popular machine learning algorithms. There are many machine learning algorithms. The difficulty is to classify methods. Here we will introduce two methods for thinking and classifying th

characteristics of the learning, so that the classification is not allowed, for example, a special feature as a category of judging criteria, so that does not have a particular attribute of the data into this category. This is called fitting, English is called overfitting literal translation is over-matching, that is, matching is too thin, a bit too. To solve this problem, it is necessary to simplify the decision tree, to remove some of the character

　In this article we will outline some popular machine learning algorithms.Machine learning algorithms are many, and they have many extensions themselves. Therefore, how to determine the best algorithm to solve a problem is very difficult.Let us first say that based on the learning
