Shafer-Dempster theorem

The Shafer-Dempster theorem provides a way to combine different sources of uncertain information about a scenario. Imagine multiple experts give their opinions on the likelihood of an event, but their information overlaps or conflicts. The theorem offers a mathematical method to merge these opinions into a single, combined belief, accounting for uncertainties and contradictions. This process helps in decision-making by integrating diverse evidence, giving a clearer overall picture. It’s foundational in Dempster-Shafer theory, which models uncertain knowledge more flexibly than traditional probabilities.
