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. WebbFor instance, simulations are often the key to feasible estimation in various non-linear contexts. Moreover, these procedures are shown to circumvent finite sample problems …
Webb21 apr. 2024 · In this setting model-based approaches are more attractive, but put stronger requirements on correct model specification. As expected, the results of the simulation study showed that the weighting approach (HT) performed poorly across a wide range of scenarios, despite a simplified scenario where uncorrelated variables were excluded.

WebbFor example, Hermans et al., 2024 have shown that current simulation-based inference algorithms can produce posteriors that are overconfident, hence risking false inferences. In this work, we introduce Balanced Neural Ratio Estimation (BNRE), a variation of the NRE algorithm designed to produce posterior approximations that tend to be more ...
