Data Mining可分为三大类六分项来说明： Classification和Clustering属于分类区隔类； Regression和Time-series属于推算预测类； Association和Sequence则属于序列规则类。 Classification是根据一些变量的数值做计算，再依照结果作分类。（计算的结果最后会被分类为几个少数的离散数值，例如将一组数据分为"可能会响应"或是"可能不会响应"两类）。Classification常被用来处理如前所述之邮寄对象筛选的问题。我们会用一些根据历史经验已经分类好的数据来研究它们的特征，然后再根据这些特征对其他未经分类或是新的数据做预测。这些我们用来寻找特征的已分类数据可能是来自我们的现有的客户数据，或是将一个完整数据库做部份取样，再经由实际的运作来测试；譬如利用一个大型邮寄对象数据库的部份取样来建立一个Classification Model，再利用

It's been years since I last ventured to answer "How to choose Data Mining Tools". This article mainly elaborates the following two core viewpoints: 1. There is no best tool, or rather, the best tool for everyone. 2. The most useful tools are those that can meet the vast majority of data mining tasks you need. The m

R R (http://www.r-project.org) is used for statistical analysis and graphical computer language and analysis tools, in order to ensure performance, its core computing module is written in C, C ++ and FORTRAN. It also provides a scripting language (R) for ease of use. The r language is similar to the s language developed by Bell Labs. R supports a series of analysis technologies, including statistical testing, predictive modeling, and data visualizatio

In today's big data era, data is money. With the transition to an application-based domain, data shows exponential growth. However, 80% of the data is unstructured, so it requires a program and method to extract useful information and convert it into an understandable and available structured form. A large number

Enterprise Development CRM, the goal is two aspects, one is to help marketing staff manage their own sales process, the second is from customer data analysis of mining service development direction. The latter is the most important ... Faced with brutal market competition, all enterprises are sparing no effort to win new customers. However, the existing old customers also contain huge business opportunitie

Nine common data mining algorithms are provided in SQL Server. These algorithms are used in different data mining application scenarios. Next we will analyze and discuss each algorithm one by one. 1. Decision Tree Algorithm A decision tree, also known as a decision tree, is a tree structure similar to a binary tree or

Data Mining is effective, novel, and potentially useful from massive, incomplete, noisy, fuzzy, and random data sets, and the extraordinary process of an understandable model. It is a wide range of cross-discipline, including Machine Learning , Mathematical Statistics , Neural Network , Database , Pattern Recognition , Rough Set , Fuzzy Mathematics And oth

I used python to implement algorithms for data mining in my statistics department. At that time, I started the tutorial "machine learning practice", which also used python. However, it was recently discovered that the recruitment requirements for data mining engineers generally involve JAVA, and the NPC

I. Challenges of the Times Over the past more than 10 years, the ability of people to use information technology to produce and collect data has increased dramatically, and countless databases have been used for business management, government office, Scientific Research and engineering development, and this momentum will continue to develop. A new challenge has been raised: In an era known as information explosion, an overdose is almost a problem th
