Generative diffusion model surrogates for mechanistic agent-based biological models [PDF]

open access: yesMachine Learning: Science and Technology
Mechanistic, multicellular, agent-based models are commonly used to investigate tissue, organ, and organism-scale biology at single-cell resolution. The Cellular-Potts Model (CPM) is a powerful and popular framework for developing and interrogating these
