I plan to organize the basic concepts and algorithms of data mining, including association rules Mining, classification, clustering of common algorithms, please look forward to. Today we are talking about the most basic knowledge of association rule mining. Association rules mining has been widely used in electric bus

March 10, there are netizens in the group to share the suspected Xiaomi blockchain products "encrypted rabbit" link, Xiaomi or will launch their own blockchain game project.First, about the millet blockchain pet "Crypto Rabbit"From the exposure of the 2 group chat, Xiaomi should formally enter the Blockchain game field.From millet "encrypted rabbit" to see the blockchain game, Mining has become a marketing toolWelcome to Encrypt Rabbit Blockchain Pet

Tags: using SP data, BS, users, technical objects, different methods First: Data type, Different attributes of an object are described by different data types, such as age --> int; birthday --> date. Different types of data mining must be treated differently. Second: Data quality, Data quality directly affects the quality of the mining results. Generally, noise, outlier, data omission, and duplication in da

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 Set: if the frequency of the item set is greate

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, cross-reporting, hypothesis testing, etc. Data mining is a very clear definition of the

The Application of association rule Mining algorithm in life is everywhere, it can be seen in almost every e-commerce website.To give a simple examplesuch as Dangdang, when you browse a book, you can see some package recommendations on the page, book + related books 1+ related books 2+...+ Other items = How many ￥And these packages are likely to suit your appetite, and you might have bought a whole package for this recommendation.This is different fro

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 mining objectives, the need to extract from the busines

I recently read an article about View MiningOf KDDThe mining algorithms of mining and summarizing customer reviews (kdd04) are classic and are hereby recorded. The problem to be solved in this paper is, Identify users' comments(Positive or negative. The following is an example of a digital camera: Digital Camera: feature: photo quality positive: 253 Algorithm process 1. main steps: Compared with the prev

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 Data Mining Open source project (Mahout originally re

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 data Mining tool Weka to carry on the management rule

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

Deep Mining of Python and metabases II [experience] and deep mining of python The previous article solved some of the namespace problems that may occur during the generation of instance objects by calling class objects. This time we go back to the next layer to see how class objects are generated. We know that the type () method can view the type of an object, or determine which class the object is generate

Data Mining is the non-trivial process of obtaining effective, novel, potentially useful, and ultimately understandable patterns from a large amount of data. A broad view of data mining: Data mining is the process of "digging" interesting knowledge from a large amount of data stored in databases, data warehouses, or other repositories. Data
