Feature selection is an important processing step in machine learning and the design of pattern recognition system. Feature selection involves identifying a subset of the most useful features that produces compatible results as the original entire set of features. In this work, fuzzy entropy of each feature is calculated and filtered using linear search as well as redundancy is removed to judge on features suitability. The obtained results indicate that the generated features are of maximum relevance and with minimum degree of redundancy. Finally the proposed algorithm is applied to four different data sets, with four different threshold values and also compared against FCBF algorithm. Also the performance metrics (sensitivity, specificity and accuracy) and dimension metrics (features than the FCBF algorithm.selected) are compared for all the four data sets. All the results show that the proposed algorithm can give significant results for the feature selection process.
