The Support Vector Regression with Adaptive Norms
Chunhua Zhang, Dewei Li, Junyan Tan · Procedia Computer Science · 2013
This study proposes a new method for regression – lp-norm support vector regression (lp SVR). Some classical SVRs minimize the hinge loss function subject to the l2-norm or l1-norm penalty. These methods are non-adaptive since their penalty forms are fixed and pre-determined for any types of data. Our new model is an adaptive learning procedure with lp-norm (0 < p < 1), where the best p is automatically chosen by data. By adjusting the parameter p, lp SVR can not only select relevant features but also improve the regression accuracy. An iterative algorithm is suggested to solve the lp SVR efficiently. Simulations and real data applications support the effectiveness of the proposed procedure.
