Tokenised Flow Matching for Hierarchical Simulation Based Inference

Giovanni Charles, Cosmo Santoni, Seth Flaxman, Elizaveta Semenova

ICML 2026poster

The cost of simulator evaluations is a key practical bottleneck for Simulation Based Inference (SBI). In hierarchical settings with shared global parameters and exchangeable site-level parameters and observations, this structure can be exploited to improve simulation efficiency. Existing hierarchica…

Seq2Seq Surrogates of Epidemic Models to Facilitate Bayesian Inference

Giovanni Charles, Timothy M. Wolock, Peter Winskill, Azra Ghani, Samir Bhatt, Seth Flaxman

AAAI 2023technical

Epidemic models are powerful tools in understanding infectious disease. However, as they increase in size and complexity, they can quickly become computationally intractable. Recent progress in modelling methodology has shown that surrogate models can be used to emulate complex epidemic models with…
