This paper introduces a modified version of a genetic algorithm with aggressive mutation (GAAM), one of the genetic algorithms (GAs) used for feature selec
We use Support Vector Machine (SVM) as the base learning algorithm, which is trained with a diverse set of features that cover both statistical and linguistic characteristics. We develop a feature selection algorithm using Genetic Algorithm (GA) for determining the most relevant set of features. ...
But we will have to struggle if the feature space is really big. Genetic algorithm is one solution which searches for one of the best feature set from other features in order to attain a high accuracy.Installation:$ pip install feature-selection-ga...
At the data pre-processing and training phase of the proposed GANBADM, Genetic Algorithm (GA), which is a random selection method as shown in Algorithm 1 has been used as a feature search algorithm which is part of the first step of wrapper feature selection technique as shown in Fig. 1...
