Data Mining algorithm-apriori Algorithm (association Rules)Apriori algorithm is a basic algorithm in association rules. The association rule Mining algorithm was proposed by Rakesh Agrawal and Ramakrishnan Srikant two PhD in 1994. The purpose of association rules is to find out the relationship between items and items in a da
Web-oriented data mining
There is a large amount of data information on the Web, and how to apply these data to complex applications has become a hot research topic in modern database technology. Data mining is to find out the hi
Association Rules Mining (Association rule Mining) is one of the most active research methods in data mining, which can be used to discover the connection between things, and to discover the relationship between different goods in supermarket transaction database. (Beer and diapers)

This book provides a comprehensive overview of data mining, covering five topics: data, classification, correlation analysis, clustering, and anomaly detection. In addition to anomaly detection, each topic has two chapters. The previous chapter covers basic concepts, representative algorithms, and evaluation techniques, and the latter chapter discusses advanced c

Disadvantages: need to scan the database multiple times, inefficient. Association Rules cluster System ( ARCS
Brief introduction
In data mining with WEKA, part 1th: Introduction and regression, I introduced the concept of data mining and free open source software Waikato Environment for Knowledge Analysis (WEKA), which can be used to mine data to obtain trends and patterns. I also

Recently is going to learn some knowledge of data mining, began to read some related blog, but too fragmented, has not a more systematic understanding of this. Weekend in the library wandering, accidentally saw "big talk data Mining" a book, found that the more organized, and quite suitable for the introduction, so rea

Data Mining Classification Technology
Many specific classification technologies have been developed since the classification problem was raised. The following describes the four most common classification technologies.AlgorithmImplementation and optimization are not the focus of this book, so we try to express these technologies in languages that can be understood by application personnel. And we will4Cha
Data mining makes proactive, knowledge-based decisions by predicting future trends and behaviors. The goal of data mining is to discover the hidden and meaningful knowledge from the database, which mainly has the following five kinds of functions.
1. Automatically predict trends and behaviors
