Semisupervised Bacterial Heuristic Feature Selection Algorithm for High-Dimensional Classification with Missing Labels

Abstract: Feature selection is a crucial method for discovering relevant features in high-dimensional data. However, most studies primarily focus on completely labeled data, ignoring the frequent occurrence of missing labels in real-world problems. To address high-dimensional and label-missing problems in data classification simultaneously, we proposed a semisupervised bacterial heuristic feature selection algorithm. To track the label-missing problem, a k-nearest neighbor semisupervised learning strategy is designed to… Show more

“…The heuristic method is based on intuition which employs a practical method that is not guaranteed to be optimal or perfect approach but it is nevertheless sufficient to yield an approximation well [15]. The evaluation of dependency between the target and predictor features, and the evaluation of independence among predictor features are key concepts in running the heuristic method [16]. There are 3 statistical tests usually used for the dependency or independency test namely the Chi-square test for evaluating dependency among 2 categorical features [17], Pearson's correlation test for evaluating dependency among two numerical features [18], and one-way Analysis of Variance (ANOVA) for evaluating dependency between the categorical and numerical features [19].…”

“…This is because MH algorithms generate a feasible solution space with a stochastic algorithm, search the space for solutions in each iteration, evaluate individual fitness through the fitness function, and perform updates to produce the optimal solution 3 . The MH algorithms have shown advantages in many fields, including global optimization 4 , 5 , feature selection 6 , 7 , sentiment classification 8 10 , and case forecasting 11 . Considering the no free lunch (NFL) theorem, no algorithm can perform well on every optimization problem 12 , it is significant to study the MH algorithms.…”
