摘要
Support vector machines with Gaussian kernel are used in classification tasks with linear non-separable data. The Gaussian kernel is parametrized by two values (hyperparameters): C, gamma. Hyperparameters selection, also known as model selection, affects the generalization performance of classifier. Retaining high generalization performance is vital to achieving good prediction results on uknown datasets. There is no strict rule for proper model selection. The range of hyperparameters' values is wide, so this is a time consuming task in general. In our approach genetic algorithm is exploited to find optimal hyperparameters values.
