+Deep Cox Mixtures
+------------------
+The Cox Mixture involves the assumption that the survival function
+of the individual to be a mixture of K Cox Models. Conditioned on each
+subgroup Z=k; the PH assumptions are assumed to hold and the baseline
+hazard rates is determined non-parametrically using an spline-interpolated
+Breslow's estimator.
