CoxNTF builds a survival-probability-weighted tensor of covariates, factorizes it with non-negative tensor factorization, and uses the resulting meta-scores in a Cox model to get interpretable clusters with prediction accuracy comparable to Coxnet.

CoxNTF: A New Approach for Joint Clustering and Prediction in Survival Analysis
CoxNTF builds a survival-probability-weighted tensor of covariates, factorizes it with non-negative tensor factorization, and uses the resulting meta-scores in a Cox model to get interpretable clusters with prediction accuracy comparable to Coxnet.
