I'm a beginner here, and I had a couple questions about DeepSurv. When doing "normal" cox proportional hazards survival analysis, we can analyze the impact of each covariate on the survival outcome (with hazard ratios) and calculate p-values. Does DeepSurv have the same univariate capabilities or is it supposed to be used on ALL the covariates at once? If so, how do we know which covariates have a statistically significant effect on the survival?
Edit: When running DeepSurv with a certain number of epochs, running it over and over results in different concordance indices. They seem to vary drastically (0.42 to 0.15 to 0.55, etc.). Am I doing something wrong?
