[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

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

Close down properties (downward Closure property)
If an item set satisfies a minimum support requirement, then any non-empty set of the set of items must satisfy this minimum support degree. Introduction to Apriori algorithm
Apriori algorithm is a frequent itemsets algorithm for mining Association rules, whose core idea is to close and detect the frequent itemsets through the generation of candidate sets.

Suppose you are the manager of a supermarket, you will want to understand the customer's shopping habits. You'll want to know what customers might buy at one time in the shopping, so you can arrange the shelves to make a bigger profit. This is the Association Rules (Association Rule). Its manifestations are as follows:bread⇒milk[support=10%;confidence=60%] Bread\rightarrow milk [support=10\%; confidence=60\%]
The Support degree (support) and Confidence (confidence) of a rule are two metrics o

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
