Abstract

The performances of support vector regression estimation were analyzed. It was found that the insensitive factor ε can affect the performance of support vector regression estimation significantly. The noise inside the sample data should be considered in determining the insensitive factor ε when support vector regression was employed. A novel support vector regression based on non-uniform lost function (NLF-SVR) was proposed to deal with different noise data density function in different region. The formulation and algorithms of computing NLF-SVR were given. The test example showed that the outcomes of NLF-SVR are better than that of conventional SVR. NLF-SVR can be applied in physiological systems modeling.
