DATA MINING TECHNIQUES. What is data mining? by Tanmay Terkhedkar
There are many different classification algorithms used in data mining, each with its own strengths and weaknesses. Some of the most popular algorithms include decision trees, logistic regression, naive Bayes classification, k-nearest neighbors, and support vector machines. The choice of which classification algorithm to use depends on the.
ClassificationBased Approaches in Data Mining
Data mining techniques draw from various fields like machine learning (ML) and statistics. Here are a few common data mining techniques: Classification is the task of assigning new data to known or predefined categories. For example, sorting a data set consisting of emails as "spam" or "not spam."

with D_1 and D_2 subsets of D, 𝑝_𝑗 the probability of samples belonging to class 𝑗 at a given node, and 𝑐 the number of classes.The lower the Gini Impurity, the higher is the homogeneity of the node. The Gini Impurity of a pure node is zero. To split a decision tree using Gini Impurity, the following steps need to be performed.
Basic Concept of Classification (Data Mining)
Classification in data mining is a key technique that involves predicting the class of new data points based on historical data. Classification algorithms learn patterns from labeled data and use these patterns to assign new data points to specific classes. This technique has numerous applications in fields such as image and speech recognition.

Data Mining - Classification & Prediction. There are two forms of data analysis that can be used for extracting models describing important classes or to predict future data trends. These two forms are as follows −. Classification models predict categorical class labels; and prediction models predict continuous valued functions.
PPT Data Mining Concepts and Techniques — Chapter 1 — — Introduction
Data mining relies on computers to extract, analyse, and examine patterns in large quantities of data to glean insights. Businesses, brands, and individuals can use this process to learn about trends and patterns and even predict future probabilities. It has many uses and applications, from finance to media to the medical industry.
