Support vector machine (SVM) is a renowned machine learning technique, which has been successfully applied to solve many practical pattern classification problems. One of the difficulties in successful implementation of SVM is its different parameters (i.e., kernel parameter(s), penalty parameter (C) and the features available in the dataset), which should be well adjusted during the training process. In this paper, a new approach called smart adaptive particle swarm optimization–support vector machine (SAPSO–SVM) is developed to adapt the parameters of optimization algorithm (i.e., inertia weight and acceleration coefficients) to the latest changes in the search space, so that each particle explicitly explores the search space based on the latest changes made to Personal best, Global best and other particle locations. In this algorithm, using the changes in Personal best and Global best at each stage of …
