Abstract The generative approaches and the discriminative approaches are two kinds of paradigms for solving classification problems. To exploit the advantages of these approaches, a linear hybrid of generative/discriminative model (LHGD) is proposed, and a learning algorithm of LHGD based on genetic algorithms (LHGD_GA) is designed. LHGD_GA regards hybrid parameter learning of the linear hybrid classification model as an optimization problem, and utilizes genetic algorithms to find the best hybrid parameters of linear hybrid classification model. The experimental results show that the linear hybrid generative/discriminative classifier is better than or similar to the better classifier of two base classifiers on most datasets.
