If you have a shopping website, how do you recommend products to your customers? This function is available on many e-commerce websites. You can easily build similar functions through the data mining feature of SQL Server Analysis Services.
It is divided into three parts to demonstrate how to implement this function.
1. Build a Mining Model

independent and has no correlation.If that is less than 0, the description is negatively correlated, and one value increases by another.Note that correlations do not imply causality, and if A and B are relevant, it does not mean that a causes B or B to cause a.3. Covariance of numeric dataCovariance and variance are two similar measures that evaluate how the two properties change together. The mean values of A and B are also known as expectations.The covariance of A and B is defined as: For

If you are familiar with Java, we often think of WEKA when thinking about data mining, and the data mining: Practical machine learning tools and techniques written by Ian H. Witten has a Chinese version, so there are many users. Recently, I want to use python to process
In various data mining algorithms, association rule mining is an important one, especially influenced by basket analysis. association rules are applied to many real businesses, this article makes a small Summary of association rule mining. First, like clustering algorithms, association rule
Ten classic algorithms in machine learning and Data Mining
Background:
In the early stage of the top 10 algorithm, Professor Wu made a report on the top 10 challenges of Data Mining in Hong Kong. After the meeting, a mainland professor put forward a similar idea. Professor Wu felt very good and began to solve the probl
Customer churn is a big problem facing banks in the increasingly competitive market. By analyzing the reasons of bank customer churn, this paper puts forward a method of establishing customer churn prediction model. By using the model, we find out the forecast loss group, forecast the loss trend, and then formulate effective control strategy to minimize the customer churn rate. It provides a new research idea and analysis method for customer churn prediction.
[Key words] customer churn loss Pred
1 Introduction
With the increasing popularity of the Internet, various forms of information generation and collection have led to the explosion. The competitive trend of modern society requires real-time and deep analysis of this information, although there is now a more powerful information storage and retrieval system. But users are becoming more and more difficult to analyze and use the information they have. How to effectively organize and utilize a large amount of information, so that user
Some people work very original, there are some very new things every year. Some people have a lot of articles, but mainly follow others ' work. There are many paper machine in the database field. In some places, the whole group is a big paper machine.Personal feeling database researchers tend to think of data mining as a sub-domain of a database, and thus have lower rating for

PS: Due to space issues, this blog mainly introduces the project Understanding Problem in the data mining standardization process. The remaining five aspects are as follows, in particular, modeling and other components involving specific algorithms will be written in the follow-up blog in the form of open-source software such as orange and knime or some Python applets.

This book is mainly used for beginners, very basic, suitable for sophomore, junior to see the children, of course, if you are a senior or a senior senior not seen machine learning is also applicable. Whether it's studying intelligence or doing other things, machine learning is a must. You see GFW all use machine study, we also have to science.(full-text structure) In fact, I think, learn a subject, List a p
