The inference methods … Webb21 mars 2024 · Classical inference, including Markov Chain Monte Carlo (MCMC), is based on brute-force search: trying a large number of solutions, often by improving on previously found ones. This is very expensive at run-time and not practical from the point of view of an animal facing immediate danger.
