selection condition is secondary, just how to build a good model. But in data mining, it's not exactly the case. In data mining, the guidelines play a central role. (There are, of course, some independent exceptions to the norm in statistics.) GIFI's nonlinear multivariate analysis of schools is one of them. For examp

Business Intelligence product Data mining focuses on solving four types of problems: classification, clustering, correlation, prediction (which will be explained in detail after the four types of questions), while conventional data analysis focuses on solving other data analysis problems, such as descriptive statistics

I used to make some detours on Data Mining Research. In fact, from the origins of data mining, we can find that it is not a brand new science, but a combination of research achievements in statistical analysis, machine learning, artificial intelligence, and databases, in addition, unlike expert systems and knowledge ma

,I2,I3} has a number of occurrences of 2,{i1,i2}, so the confidence level is 2/4=50%Similarly, it can be calculated{i1,i3}=>i2,confidence=50%{i2,i3}=>i1,confidence=50%i1=>{i2,i3},confidence=33% i2=>{i1,i3},confidence=28%i3=>{i1,i2},confidence=33%That is, when a user buys a i1,i3, the system can refer i2 together as a package to the user, as these three items are frequently purchased together.However, through the description of the entire process of the algorithm, we can see that the Apriori algo

Use excel for data mining (4) ---- highlight abnormal values and excel Data Mining Use excel for data mining (4) ---- highlight Abnormal Values After configuring the environment, you can use excel for

1. Define the mining target To understand the real needs of users, to determine the target of data mining, and to achieve the desired results after the establishment of the model, by understanding the relevant industry field, familiar with the background knowledge. 2. Data acquisition and processing of clear

The previous article introduced the open source data mining software Weka to do Association rules mining, Weka convenient and practical, but can not handle large data sets, because the memory is not fit, give it more time is useless, so need to carry out distributed computing, Mahout is a based on Hadoop Cloth

With the intensification of market competition, China Telecom is facing more and more pressure, customer churn is also increasing. From the statistics, the number of fixed-line PHS this year has exceeded the number of accounts. In the face of such a grim market, the urgent task is to make every effort to reduce the loss of customers. Therefore, it is necessary to establish a set of models that can predict customer churn rate in time by using data

This is a computer database storage and management class of high-quality pre-sale recommendation "MATLAB data Analysis and mining actual combat". A number of senior data mining experts more than 10 years of practical experience crystallization, in-depth interpretation of the various aspects of

Purpose of collecting web logsWeb log mining refers to the use of data mining technology, the site user access to the Web server process generated by the log data analysis and processing, so as to discover the Web users access patterns and interests, such information on the site construction potentially useful and unde

Spatial Data Multimedia Data For example, image data Description-based retrieval system: keywords, titles, dimensions, etc. Content-based retrieval system: color composition, texture, shape, object and wavelet transformation. Time series data and sequence data Trend Analysis

only 1. So the count of conditional pattern bases is determined by the minimum count of nodes in the path.Depending on the conditional pattern base, we can get the conditional FP tree for that commodity, for example i5:According to the conditions of the FP tree, we can do a full array of combinations, to get the frequent patterns excavated (here to the commodity itself, such as i5 also counted in, each commodity mining out of the frequent pattern mus
