C4.5 algorithm Wikipedia

2019-3-25 · C4.5 is an algorithm used to generate a decision tree developed by Ross Quinlan.[1] C4.5 is an extension of Quinlan"s earlier ID3 algorithm. The decision trees generated by C4.5 can be used for classification, and for this reason, C4.5 is often referred to as a statistical classifier. In 2011, authors of the Weka machine learning software

Data mining — Decision tree classification IBM

2016-5-18 · Intelligent Miner supports a decision tree implementation of classification. A Tree Classification algorithm is used to compute a decision tree. Decision trees are easy to understand and modify, and the model developed can be expressed as a set of decision rules. This algorithm scales well, even where there are varying numbers of training examples and considerable numbers of attributes in

Data mining with decision trees and decision rules

This paper describes the use of decision tree and rule induction in data-mining applications. Of methods for classification and regression that have been developed in the fields of pattern recognition, statistics, and machine learning, these are of particular interest for data mining since they utilize symbolic and interpretable representations.

Data Mining Decision Tree (DT) Algorithm [Gerardnico]

FFTrees Create, visualize, and test fast-and-frugal decision trees (FFTs). FFTs are very simple decision trees for binary classification problems. FFTs can be preferable to more complex algorithms because they are easy to communicate, require very little information, and are robust against overfitting.

Decision tree pruning Wikipedia

2019-3-24 · Pruning is a technique in machine learning that reduces the size of decision trees by removing sections of the tree that provide little power to classify instances. Pruning reduces the complexity of the final classifier, and hence improves predictive accuracy by the reduction of overfitting.

What is a Decision Tree Diagram Lucidchart

2019-4-7 · A decision tree can also be used to help build automated predictive models, which have applications in machine learning, data mining, and statistics. Known as decision tree learning, this method takes into account observations about an item to predict that item"s value. In these decision trees, nodes represent data rather than decisions.
