Abstract:
This study performs a comparative analysis of the performance of Machine Learning, neural networks and traditional survival analysis techniques. The techniques compared are the traditional Cox proportional hazards (CPH) model, Machine Learning Random Survival Forest (RSF) technique and neural networks such as DeepSurv. These techniques are applied to the study of Covid-19 cases of patients diagnosed in the city of Bucaramanga between March 2020 and March 2023. This study demonstrates better performance was obtained with the Random Survival Fores technique in predicting the survival function measured through the C – index, Brier score and AUC.
