The Dempster Shafer method is one of many techniques that can be used to diagnose nasopharyngeal carcinoma. The Dempster Shafer method is a mathematical approach to proofs that combines different bits of information (proofs) to estimate the probability of an event. It is based on the functions of trust and reasonable reasoning.
