I. Concepts Association Rule Mining: discovering interesting and frequent patterns, associations, and correlations between item sets of a large amount of data, such as the food database and relational database. Measurement of the degree of interest of association rules:Support,Confidence K-item set: a set of K items Frequency of the item set: number of transactions that contain the item set Frequent Item Se

transaction by user shell+ip+ hostname according to different user's login (all three are the same user) Based on this, the basic principle of mining 2 algorithm for user input command sequence frequent pattern is realized. The fp-growth algorithm mainly solves the collection of frequent items where the number of occurrences reaches a certain threshold in multiple sets. A FP tree is a compressed representation of input

Several basic concepts and two basic algorithms for association rules are described in the previous few. But actually in the commercial application, the writing algorithm is less than, understands the data, grasps the data, uses the tool to be important, the preceding basic article is to the algorithm understanding, this article will introduce the open source utilizes the

What is the difference between data Mining (mining), machine learning (learning), and artificial intelligence (AI)? What is the relationship between data science and business Analytics? Originally I thought there was no need to explain the problem, in the End data

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

First talk about the problem, do not know that everyone has such experience, anyway, I often met.Example 1, some websites send e-mails to me every few days, each e-mail content is something I do not interest at all, I am not very disturbed, to its abhorrence.Example 2, add a feature of a MSN robot, a few times a day suddenly pop out a window, recommend a bunch of things I don't want to know, annoying ah, I had to stop you.Every audience just want to see what he is interested in, rather than some
