Supervised Machine Learning: A Review of Classification Techniques
TL;DR: The goal of supervised learning is to build a concise model of the distribution of class labels in terms of predictor features, and the resulting classifier is then used to assign class labels to the testing instances where the values of the predictor features are known, but the value of the class label is unknown.
Journal ArticleDOI
Machine learning: a review of classification and combining techniques
TL;DR: Various classification algorithms and the recent attempt for improving classification accuracy—ensembles of classifiers are described.
Handling imbalanced datasets: A review
TL;DR: This paper describes various techniques for handling imbalanced dataset problems, and hopes that the references cited will cover the major theoretical issues, guiding the researcher in interesting re- search directions and suggesting possible bias combinations that have yet to be explored.
Journal ArticleDOI
Decision trees: a recent overview
TL;DR: Basic decision tree issues and current research points are described, guiding the researcher in interesting research directions and suggesting possible bias combinations that have yet to be explored.
Journal ArticleDOI
Data Preprocessing for Supervised Leaning
TL;DR: This paper presents the most well know algorithms for each step of data pre-processing so that one achieves the best performance for their data set.
