I am using DeepSurv model from R package survivalmodels, which is a wrapper of the equivalent python package. There is L2 regularisation https://github.com/jaredleekatzman/DeepSurv/blob/master/notebooks/DeepSurv%20Example.ipynb in the original package (“L2_reg”), and in pysurvival, https://square.github.io/pysurvival/models/nonlinear_coxph.html (“l2_reg”), but I can not see how to tune this parameter out of R?
