Using data and samples to establish operational knowledge is machine learning.Machine Learning:Machine Learning has a long history and many textbooks have explained many useful principles. Here we focus on several of the most relevant topics.Formalizing learning:First, let's formalize the most general machine

After discussing the "brush list", we will discuss the effect of "hoarding goods". The electric Dealer's various creation festival has created batch after batch of Chop hand party, these chopping hands often advance to buy goods in advance into the shopping cart, may have mother and child, may have men's, may have children's books, or literature, social science, and so on, and so on the day of the list. If you use these orders to calculate the association

The historical origins, knowledge representation, reasoning strategies, similarity of results evaluation, the relative concentration of researchers, and application fields of various learning methods are comprehensively considered. Machine learning methods are divided into the following six categories:
1) Empirical inductive

Earlier, we mentioned supervised learning, which corresponds to non-supervised learning in machine learning. The problem with unsupervised learning is that in untagged data, you try to find a hidden structure. Because the examples

Perspective: This book is an advanced version ofProgramming collective Intelligence. They have the same purpose (let programmers begin to understand machine learning), but this book includes some mathematical knowledge, examples and Phython program fragments. If you are interested, I suggest you read this book after reading "programming collective Intelligence".

Which language is the most popular programming language? The answer should be clear. Python, Java, and R are the most popular skills when it comes to machine learning and data science. If you want to focus on deep learning instead of general machine
We have developed a false news detector using machine learning and natural language processing, which has an accuracy rate of more than 95% on the validation set. In the real world, the accuracy rate should be lower than 95%, especially with the passage of time, the way the creation of false news will change.
Because of the rapid development of natural language processing and
, the above classification idea is the idea of SVM. Can be expressed as: SVM is trying to find a super plane to split the sample, the sample in the positive and inverse examples with the super-plane, but not very perfunctory simple separation, but do the best to make the interval between the positive and inverse of the largest margin. In this way, the results of the classification are more credible, and for the unknown new samples have a good classifi

A typical example of unsupervised learning is clustering. The purpose of clustering is to bring together things that are similar, and we do not care what this class is. Therefore, a cluste

. It is used to organize clusters of large computers. The second application is the analysis of social networks. There is also market segmentation. Many companies have large databases that store consumer information. So, you can retrieve these customer data sets, automatically discover the market classification, and automatically divide the customer into different market segments so that you can automatically and effectively sell or sell together in different segments of the market. Finally, uns
