Wang Green Garden Cammeying Guangzhou PLA Sports Institute 510502 Absrtact: This paper reveals a way for librarians to carry out information service in the future Digital Library, discusses the basic principles and methods of data mining and web mining, and emphasizes the necessity for librarians to master the new technology of
Book next to the aboveUsing support vector Machine (SVM) for data mining in R (above)http://blog.csdn.net/baimafujinji/article/details/49885481The second way to use the SVM () function is to build a model based on the data given. This is a more complex form, but it allows us to build models in a more flexible way. Its

Python Data analysisWhy do you choose Python for data analysis?Python will inevitably be close to other open source and commercial domain-specific programming languages/tools such as R, MATLAB, SAS, Stata, etc. for data analysis and interaction, exploratory computing, and data
remainders graph to express the dependency between variables, variables are represented by nodes, and dependencies are represented by edges .Ancestor, parent, and descendant nodes. A node in a Bayesian network, if its parent node is known, its condition is independent of all its non-descendant nodesEach node comes with a conditional probability table (CPT)that represents the contact probability of the node and parent node Modeling stepsCreate a network structure (knowledge of hideaway industry
I personally think we can directly discuss data mining.AlgorithmAnd WEKA are too impatient to use. I learned data mining methods directly from the beginning. Some methods are difficult and boring. What I often think about is not the method itself, but "What is this ?". After WEKA is used, some things gradually become clearer, because the input and output give p
The previous article introduced the ARFF format, which is a proprietary WEKA format. Generally, We need to extract or obtain data from other data sources. WEKA supports conversion from CVS or from databases. The interface is shown in figure The WEKA installation directory contains a data directory containing some test da
I was fortunate enough to take the MOOC college Hadoop experience class at the academy.This is the little Elephant College hadoop2.

the WTW:The essence is similar.Another understanding: If we consider the constraints in SVM as a filtering algorithm, for a number of points in a plane,It is possible that some margin non-conforming methods will be ignored, so this is actually a reduction of the problem of the VC dimension, which is also an optimization direction of the problem.With the condition of M > 1.126, better generalization performance was obtained compared to PLA.Taking a circle midpoint as an example, some partitionin

Large variance ... ）2) If the original data of the various dimensions of the operation, the variance covariance, only a matrix is represented.The above-mentioned paragraph is clear, the core of PCA is: the original input data are cleverly all the dimensions of the value, the variance and covariance are put into a matrix.The goal of optimization is: The variance is large, the
One, unsupervised learning1. Clustering: It is a process of classifying and organizing data members with similar data concentrations in some aspects. Therefore, a cluster is a collection of some data instances. Clustering techniques are often called unsupervised learning.Second, K-means clustering1, K-means algorithm:
