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
Ck:candidate itemset of size klk:frequent itemset of size kL1 = {Frequent items};for (k = 1; Lk! =?; k++) does begin Ck+1 = candidates generated from Lk; For each transaction t in database does increment the count of all candidates in ck+1 that is contained in T lk+1

Content recommendationNew Internet: Big Data Mining provides a comprehensive overview of how data mining technology can be used to extract and generate business knowledge from a wide variety of structures (databases) or unstructured (WEB) mass data. The author combs a variet
A bunch of online searches, and finally the links and differences between these concepts are summarized as follows:
1. Data mining: Mining is a very broad concept. It literally means digging up useful information from tons of data. This work bi (business intelligence) can be done,
Recently, I have the opportunity to access some data mining things.I personally feel that this technology will certainly have a great development prospect.So I will use this article to explain my views on data mining.The concept of data mining is explained step by step.

But recently found that the recruitment requirements of data mining engineers generally have Java, and the NPC
Today found a very good blog (http://www.RDataMining.com), Bo Master is committed to research the R language in data mining applications, just recently want to learn a system of r language and data mining the entire process, read the content of this blog, the heart of a long time can not calm. The decision starts today
Brief introduction
In the two articles before the "Data mining with WEKA" series, I introduced the concept of data mining. If you haven't read data mining with Weka, part 1th: Introduction and regression and

Just a few, say something:Basic article:1. Reading "Introduction to Data Mining", this book is very easy to understand, there is no complex advanced formula, very suitable for people to get started. You can also use this book for reference "Data mining:concepts and Techniques". The second is thicker, but also a bit more knowledge of

Data Mining is the nontrivial process of acquiring effective, novel, potentially useful, and ultimately understandable patterns from large amounts of data stored in databases, data warehouses, or other repositories.

Validating a data mining model
Typically, for a particular case, we can't pinpoint which mining algorithm is the most accurate, so we define multiple mining models in a mining structure, and we get the most accurate one by validating multiple
