Abstract EN
The Support Vector Regression (SVR) model has been broadly used for response prediction.
However, few researchers have used SVR for survival analysis.
In this study, a new SVR model is proposed and SVR with different kernels and the traditional Cox model are trained.
The models are compared based on different performance measures.
We also select the best subset of features using three feature selection methods: combination of SVR and statistical tests, univariate feature selection based on concordance index, and recursive feature elimination.
The evaluations are performed using available medical datasets and also a Breast Cancer (BC) dataset consisting of 573 patients who visited the Oncology Clinic of Hamadan province in Iran.
Results show that, for the BC dataset, survival time can be predicted more accurately by linear SVR than nonlinear SVR.
Based on the three feature selection methods, metastasis status, progesterone receptor status, and human epidermal growth factor receptor 2 status are the best features associated to survival.
Also, according to the obtained results, performance of linear and nonlinear kernels is comparable.
The proposed SVR model performs similar to or slightly better than other models.
Also, SVR performs similar to or better than Cox when all features are included in model.
