[Introduction to Data Mining]-quality of data quality and quality of Introduction to Data MiningData qualityThe data used by data mining is usually collected or collected for other purposes without explicit purpose. Therefore, data quality cannot be controlled at the data source. To avoid data quality problems, data mining focuses on two aspects: detection and co

Recently saw a way to tap Bitcoin, to share with you ~Tool Preparation:Cryptotab Browser Download: https://get.cryptobrowser.site/3263622Steps:1. Download browser: (Browser download interface):2. Open the browser after installation: (Below is I open a small will dig to the bitcoin, probably every 2-3 minutes will refresh the mining situation):3. Adjust the mining speed (when the browser has a window activit

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

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

What is digging a mine. When we talk about Bitcoin, a noun that is often referred to is "digging", so what is it about digging a mine? What is the detailed process of it? Personally, I used to know that the so-called mining is about to find a random number, so that the hash value of the block is less than a certain number, but what is the specific. I don't know... And, of course, not only that, many other concepts like the structure of blocks, the s

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

Frequent pattern mining can be a lot of patterns, but judging whether a pattern is interesting requires a pattern evaluation method. The common pattern evaluation methods are described below. (Hypothetical set of items A, B) 1. Support Degree The ratio of the number of tuples in the item set A and B to the number of all tuples, typically P (a∪b). 2. Reliability The confidence level of mode a--> B is P (b| A 3. Lifting Degree Lift (A, B) = P (a∪b

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

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 mining
