Dempster-Shafer theory
Dempster–Shafer theory is a mathematical framework for modeling uncertainty and belief. It allows for combining different pieces of evidence to make decisions or draw conclusions when information is incomplete or uncertain. Instead of assigning a single probability to an event, it uses belief functions to represent the range of possible outcomes and their plausibility. This theory is particularly useful in situations where data is ambiguous or contradictory, providing a structured way to update beliefs as new information becomes available. It helps in making reasoned decisions in fields like artificial intelligence, risk assessment, and information fusion.

Dempster-Shafer Theory is a method for reasoning about uncertainty and combining evidence from different sources. It allows us to represent what we know and don’t know about a situation. Instead of just saying something is true or false, it uses belief functions to express degrees of belief based on available evidence. This approach helps in situations where information is incomplete or ambiguous, enabling clearer decision-making and assessment of risks. Ultimately, it provides a framework for understanding how to combine varied information to reach more informed conclusions.
