tools used for data mining

Http://www.cnblogs.com/captain_ccc/articles/4093652.html This article is also the continuation of the Microsoft Series Mining algorithm Summary, the previous several mainly based on state discrete value or continuous value for speculation and prediction, the main algorithm used is three: Microsoft Decision tree Analysis algorithm, Microsoft Clustering Analysis algorithm, Microsoft Naive Bayes algorithm ,

data mining, so they are included.1. Clustering Commonly used packages: Fpc,cluster,pvclust,mclust Partitioning-based approach: Kmeans, Pam, PAMK, Clara Hierarchy-based approach: Hclust, Pvclust, Agnes, Diana Model-based approach: Mclust Density-based approach: Dbscan Drawing-based method: Plotcluster, Plot.hclust Verification-ba

the required package again.4, after learning the introductory book, you need to learn how to use Python to do data analysis, recommend a book: using Python for data analysis, this book mainly introduces the data analysis of several commonly used modules: NumPy, pandas, Matplotlib, and

valid tive methods for big data retrieval and mining. Due to the low storage cost and high query speed of hash, it is widely used in the approximate Nearest Neighbor Search of big data. The basic idea of hash is to map the data points in the original feature space into the

This article mainly introduces four knowledge points, which is also the content of my lecture. 1.PCA Dimension reduction operation; PCA expansion pack of Sklearn in 2.Python; 3.Matplotlib subplot function to draw a child graph; 4. Through the Kmeans to the diabetes dataset clustering, and draw a child map. Previous recommendation:The Python data Mining course. Introduction to installing Python and crawler"

packages are written by the R language, LaTeX, Java, and the most commonly used C language and Fortran. The version of the executable that you download will be accompanied by a batch of core features, and there are thousands of different packages based on the Cran record. Several of them are more commonly used, such as economic metrology, financial analysis, humanities research, and artificial intelligence

The algorithm in this paper only outlines the core idea, the specific implementation details of this blog "Data Mining Algorithm learning" classification under other articles, not regularly updated. Reprint please indicate the source, thank you.Referring to a lot of information and personal understanding, the ten algorithms are categorized as follows:? Classification algorithm: C4.5,cart,adaboost,naivebayes

]} = \frac{|x_{if}-x_{jf}|} {\max_{h} x_{hf}-\min_{h} X_{HF} $, where h passes all non-missing objects of property F. F is nominal or two yuan: if \ (x_{if} = x{jf}\), then \ (d_{ij}^{[f]}=0\), otherwise take 1. F is ordinal: computes the rank \ (r_{if}\) and \ (z_{if} = \frac{r_{if}-1}{m_f-1}\)and then processes it as a numeric attribute. Cosine similarityTo compare documents, each document is represented by a so-called word frequency vector, usually very long and sparse, and the t

1. a dataset consists of data objects. A Data Object (sample, instance, data point, object, and data tuples) represents an object. Ii. Attribute types An attribute is a data field that represents a feature of a data object. The a
