Binary feature selection
WebMar 17, 2024 · Feature selection problem represents the field of study that requires approximate algorithms to identify discriminative and optimally combined features. The evaluation and suitability of these selected features are often analyzed using classifiers. WebFeb 6, 2024 · Moreover, feature selection helps solve a series of decision-making cases, so it is convenient to use binary vectors to represent features . Thus, some researchers have studied the binary versions of these metaheuristic algorithms to address feature selection optimization problems and achieved relatively excellent results.
