Theoretical evaluation of feature selection methods based on mutual information
Feature selection methods are usually evaluated by wrapping specific classifiers and datasets in the evaluation process, resulting very often in unfair comparisons between methods. In this work, we develop a theoretical framework that allows obtaining the true feature ordering of two-dimensional sequential forward feature selection methods based on mutual information, which is independent of en...
متن کاملA theoretical framework for evaluating forward feature selection methods based on mutual information
Feature selection problems arise in a variety of applications, such as microarray analysis, clinical prediction, text categorization, image classification and face recognition, multi-label learning, and classification of internet traffic. Among the various classes of methods, forward feature selection methods based on mutual information have become very popular and are widely used in practice. ...
متن کاملFeature Selection Based on Joint Mutual Information
A feature/input selection method is proposed based on joint mutual information. The new method is better than the existing methods based on mutual information in eliminating redundancy in the inputs. It is applied in a real world application to nd 2-D viewing coordinates for data visualization and to select inputs for a neural network classiier. The result shows that the new method can nd many ...
متن کاملConditional Dynamic Mutual Information-Based Feature Selection
With emergence of new techniques, data in many fields are getting larger and larger, especially in dimensionality aspect. The high dimensionality of data may pose great challenges to traditional learning algorithms. In fact, many of features in large volume of data are redundant and noisy. Their presence not only degrades the performance of learning algorithms, but also confuses end-users in th...
متن کاملFeature Selection and Case Selection Methods Based on Mutual Information in Software Cost Estimation
Software cost estimation is one of the most crucial processes in software development management because it involves many management activities such as project planning, resource allocation and risk assessment. Accurate software cost estimation not only does help to make investment and bid plan but also enable the project to be completed in the limited cost and time. The research interest of th...
