WebDec 12, 2024 · 1 Answer. Dempster-Shafer Theory was studied fairly seriously in AI through the 70's and 80's. However, Dempster-Shafer theory has some serious shortcomings, that will cause an agent that uses it to make irrational decisions. These were uncovered by Pearl and others in the 80's, with more problems emerging in later years. WebJul 1, 2024 · As with probability theory, four different approaches to handling Dempster–Shafer theory may be distinguished: the axiomatic approach (formal properties of belief functions are analyzed); the naive case-based approach (a direct case-based interpretation of properties of belief functions is sought); the in-the-limit approach …
