Is brier score available for survival svm?

[xiaojialong0518]

Hello,all
I am using brier score to evaluate cox, survival svm,and RSF models. Brier score works on cox and RSF,but not on survival svm because svm doesn't have a "predict_survival_function". I am wondering if brier score can be used to evaluate survival SVM model and how am I supposed to do it. I really appreciate your help, thanks a lot.

You are correct, survival SVM can only predict a risk score and not a survival function, therefore assessing it in terms of calibration, which Brier score does, is not possible. The survival SVM can only be assessed in terms of discrimination (c-index, time-dependent ROC).
