This repository presents a feature selection algorithm that can be used on both machine learning datasets (UCI datasets) or deep feature sets.
Hybrid of two Wrapper feature selection algorithms- Opposition Based Harmony Search (OBHSA) and Manta Ray Foraging Optimization (MRFO). Populations are generated from both the methods and the final population from both are stacked and the average ranks calculated to determine importance of features. Top 'k' highest ranked features are used. The hybridization strategy is based on the paper: A Hybrid Meta-Heuristic Feature Selection Method Using Golden Ratio and Equilibrium Optimization Algorithms for Speech Emotion Recognition
To run the Hybrid OBHSA-MRFO algorithm on a feature set, first arrange the features in a csv file such that it the last column of the csv contains the original labels of the samples. Then run the following using the command prompt.
python main.py --csv_name features.csv
Other available parameters are: --csv_headers whose default value no suggests that the csv file has no headers. Change to yes if your file has headers. --generations has the default value of 20 meaning each algorithm (OBHSA and MRFO) will run for 20 generations to generate the populations. popSize has the default value of 20, i.e., the deafult size of population is 20.
