New CADENCE framework predicts individual dynamics from sparse data

Researchers have developed CADENCE, a new probabilistic framework designed to infer continuous individual trajectories from extremely sparse data snapshots. This method overcomes the limitations of existing approaches that either require dense longitudinal data or lose individual dynamics when analyzing cross-sectional data. CADENCE anchors latent dynamics to static, individual-level contexts, providing identifiability guarantees for single-timepoint trajectory inference. The framework combines a score-based spatial encoder with a Soft Mixture-of-Experts router to jointly identify individual dynamical parameters and routing functions. Tested on various benchmarks, including biological data, CADENCE matches or surpasses the performance of sequential models trained on dense data. AI

IMPACT Enables more accurate modeling of dynamic systems with limited data, potentially impacting fields from biology to physics.
