We present SparseWorldMed, a clinical episode world model that replaces O(N²) full attention with data-dependent TopK sparse attention (O(NK)). Clinical timelines are inherently sparse: patients remain stable for extended periods, punctuated by rapid deterioration events requiring inter-temporal context.
V-JEPA (Bardes et al. 2024) is integrated as the visual backbone of MedOS, a dual-process surgical world model.
We present MedOS-JEPA, an integration of the Motion-Content Joint Embedding Predictive Architecture (MC-JEPA) as the visual backbone of MedOS — a dual-process world model for clinical AI. MC-JEPA jointly learns optical flow and semantic content from surgical video via a shared ViT encoder, without pixel reconstruction.
