If you have a shopping website, how do you recommend products to your customers? This function is available on many e-commerce websites. You can easily build similar functions through the data mining feature of SQL Server Analysis Services. This article mainly demonstrates how to organize data according to the requirements of tools, and then perform mining, prediction, and analysis in Excel. In the pre

this chapter, we will introduce the main content of feature engineering, focusing on the main content of data cleansing and data feature preprocessing, including data cleansing, feature acquisition, feature processing (include pointing, normalization, normalization, etc.), feature dimensionality reduction and feature derivation. The quality of pretreatment directly affects the effect of the next model. ... 5-1 Feature Engineering Overview 5-2 Data Sample acquisition 5-3 outlier handling 5-4 Cal

Most data mining algorithms rely on numeric or categorical features, extracting numeric and categorical features from a data set, and selecting the best features.Features can be used for modeling, and models represent reality in an approximate way that machine mining algorithms can understandAnother advantage of feature selection is that the model is easier to manipulate than reality by reducing the complex

This code can be downloaded (updated tomorrow).In the previous article, the Hotspot Association rule Algorithm (1)-mining discrete data analyzes the hotspot Association rules of discrete data, and this paper analyzes the mining of the Hotspot Association rules of discrete and continuous data.1. First look at the data format (TXT document):@attribute Outlook {Sunny, overcast, rainy} @attribute temperature Nu

Two. Apriori algorithm　　As mentioned above, most association rule mining algorithms typically employ a strategy that is decomposed into two steps:　　Frequent itemsets are created with the goal of discovering all itemsets that meet the minimum support threshold, called frequent itemsets (frequent itemset).Rules are produced with the goal of extracting high-confidence rules from the frequent itemsets obtained in the previous step, called strong rules (st

The original idea of writing this book comes from the communication and learning with colleagues when working in the first company. But the trigger for releasing the book was a post on a report on the latest information on the CSDN. The questions in the post can be done in both subqueries and joins. Because of the conditions, I can not answer the details, the post of the friend can not understand my intention, let me regret. So I decided to put the idea of writing a book into action, and put thi

Because data mining can bring significant economic benefits, it is widely used in electronic commerce, especially in finance, retailing and telecom industry. In the financial field, managers can classify and rank by analyzing the customer's ability to repay and credit. This can reduce the numbness of lending and improve the efficiency of the use of funds. It can also be found that the leading factor in the repayment of the decisive role, so as to dev
