Migrating Birds Optimization-Based Feature Selection for Text Classification
This provides an incremental improvement in feature selection methods for text classification tasks, addressing computational efficiency and accuracy.
The paper tackles feature selection in text classification with many features by proposing MBO-NB, a method combining Migrating Birds Optimization and Naive Bayes, which reduces features from an average of 62,221 to 2,089 and outperforms Particle Swarm Optimization by an average of 6.9% in accuracy.
This research introduces a novel approach, MBO-NB, that leverages Migrating Birds Optimization (MBO) coupled with Naive Bayes as an internal classifier to address feature selection challenges in text classification having large number of features. Focusing on computational efficiency, we preprocess raw data using the Information Gain algorithm, strategically reducing the feature count from an average of 62221 to 2089. Our experiments demonstrate MBO-NB's superior effectiveness in feature reduction compared to other existing techniques, emphasizing an increased classification accuracy. The successful integration of Naive Bayes within MBO presents a well-rounded solution. In individual comparisons with Particle Swarm Optimization (PSO), MBO-NB consistently outperforms by an average of 6.9% across four setups. This research offers valuable insights into enhancing feature selection methods, providing a scalable and effective solution for text classification
