Abstract

Least squares support vector machine can employ equality constraints for the error instead of inequality constraints for the error. This paper is to propose English teaching quality evaluation in higher vocational colleges based on wavelet kernel least squares support vector machine. The testing results indicate that the evaluation values of teaching quality by using wavelet kernel least squares support vector machine are nearer to the actual evaluation values than by using traditional least squares support vector machine or support vector machine. In order to show the teaching quality evaluation ability of wavelet kernel least squares support vector machine, the evaluation errors and mean errors of teaching quality of the three evaluation methods are given. It can be seen that teaching quality evaluation ability of wavelet kernel least squares support vector machine is stronger than traditional least squares support vector machine or support vector machine.
