New framework SEM enables derivative-free learning for complex systems

Researchers have introduced Sparse Equation Matching (SEM), a new framework designed to discover equations governing complex systems without requiring derivative estimation. This derivative-free approach is applicable to general-order dynamical systems, overcoming limitations of prior methods that were restricted to first-order systems and relied on accurate derivative calculations. SEM was validated through simulations and subsequently applied to electroencephalography (EEG) data, where it successfully identified active brain regions and revealed task-specific connectivity patterns in participants. AI

IMPACT This derivative-free approach could expand the applicability of equation discovery in complex systems, potentially aiding research in fields like neuroscience and climate modeling.
