Consistency Based Feature Selection
Feature selection is an e ective technique in dealing with dimensionality reduction for classi cation task a main component of data mining It searches for an optimal subset of features The search strategies under consideration are one of the three complete heuristic and probabilistic Existing algorithms adopt various measures to evaluate the goodness of feature subsets This work focuses on one ...
متن کاملConsistency Measures for Feature Selection: A Formal Definition, Relative Sensitivity Comparison, and a Fast Algorithm
Consistency-based feature selection is an important category of feature selection research yet is defined only intuitively in the literature. First, we formally define a consistency measure, and then using this definition, evaluate 19 feature selection measures from the literature. While only 5 of these were labeled as consistency measures by their original authors, by our definition, an additi...
متن کاملConsistency-based search in feature selection
Feature selection is an effective technique in dealing with dimensionality reduction. For classification, it is used to find an “optimal” subset of relevant features such that the overall accuracy of classification is increased while the data size is reduced and the comprehensibility is improved. Feature selection methods contain two important aspects: evaluation of a candidate feature subset a...
متن کاملA New Framework for Distributed Multivariate Feature Selection
Feature selection is considered as an important issue in classification domain. Selecting a good feature through maximum relevance criterion to class label and minimum redundancy among features affect improving the classification accuracy. However, most current feature selection algorithms just work with the centralized methods. In this paper, we suggest a distributed version of the mRMR featu...
متن کاملRadiometric Measures for Feature Selection In Visual Servoing
The following paper discusses the issue of radiometric constraints for feature selection in the context of visual servoing. Here radiometric constraints are presented and measures are formulated to select the most optimal features in a radiometric sense from the set of candidate features. Experiment results verify the effectiveness of the proposed measures.
