How can we fully understand "Data Mining "? What is the theoretical basis of "data mining?
Figure 1 shows:In reality, human social and economic activities can always be described and recorded using data (numbers or symbols). After analyzing these data, information (knowledge) will be generated ); with this information (knowledge) to guide practice, you can make corresponding decisions; these decisions
Data | Database with the development of database technology and the extensive application of database management system, the amount of data stored in the database has increased dramatically, and many important information is hidden behind a large amount of data, if the information can be extracted from the database, it will create many potential profits for the company, The technology of mining information from massive database is called data
Inspection report pull up the finger a count, to today, start making money treasure just full three months, in other words, I have to make money treasure when a full three months of mine master! So, what are the benefits of mining? How can I get more crystals? What is the prospect of digging this "career"?...... After digging for three months, it is time for the miners to have a fairly relevant experience report.

All of the data mining code involved in this article is on my github:https://github.com/linyiqun/DataMiningAlgorithmIt took about 2 months to learn the classical algorithms of big data Mining and implement the code, which involved decision classification, clustering, link mining, mining, pattern
The Predictive modeling community (predictive modeling community) applies data mining to artifacts from software projects. This work has been very successful, and we know how to build a predictive model for the impact and inadequacy of the software, and to build a predictive model for tasks such as the Developer programming model (see the extended version of this article for more information).
That is to say, we need to change the focus of the predic

Some time ago, because the project used the algorithm of sequential mining, brother recommended me to use SPMF. Make a note here.
Let's start with a brief introduction to SPMF:
SPMF is an open source data mining platform with Java development.
It provides 51 data mining algorithm implementations for:
Sequential pattern
Absrtact: Customer relationship Management is not only a kind of management concept, but also a new management mechanism to improve the relationship between enterprises and customers, as well as a kind of management software and technology. Data mining can predict future trends and behaviors, and thus support people's decision-making well. The success of CRM lies in the successful data warehouse and data mining
Data mining refers to the non-trivial process of automatically extracting useful information hidden in data from data collection, which is represented by rules, concepts, laws and patterns, etc.2.1 Development History of data mining.....2.2 Key differences between data analysis and data miningCompared with the traditional statistical analysis technology, data mining

The previous series has talked about various kinds of knowledge, including drawing curves, scatter plots, power distributions and so on, and it becomes very important how to fit a straight line in a pile of scatter plots. This article mainly describes the Curve_fit function that calls the SCIPY extension package to achieve the curve fitting, simultaneously calculates the fitting function, the parameter and so on. Hope the article is helpful to you, if there are errors or deficiencies in the arti

For example, age is the ratio, 20 years old than 30 years old young 10 years old, can also ask for the mean value of age.Data types In addition to this classification there are other classifications, but such classification is the basic classification, mastered can be status quo.
The quality of the data is mainly: Missing attribute values, object duplication, outliers, inconsistent data, and data errors. There are many reasons for these data quality
