WebbConditional probability and Bayes’ theorem This section introduces two prerequisite concepts for understanding data assimilation theory: conditional probability and Bayes’ theorem. Conditional probability Most real-world events involve uncertainty because the occurence of a specific outcome isn’t guaranteed.

Webb14 aug. 2024 · According to the Bayes Theorem: Bayes Theorem This is a rather simple transformation, but it bridges the gap between what we want to do and what we can do. We can’t get P (Y X) directly, but we can get P (X Y) and P (Y) from the training data. Here’s an example: Weather dataset, from the University of Edinburgh
Bayes' theorem is named after the Reverend Thomas Bayes (/beɪz/), also a statistician and philosopher.
