Symbolic Weak-form Recovery of 2-D Stochastic Generators
Sai Sathvik Gullipalli, Eshwar R A
The paper introduces a weak‑form SINDy estimator that combines spatial kernels, ridge‑stabilized projection, adaptive LASSO/STLSQ selection, diagonal GLS, and a positive‑semidefini…

Data-Driven Weak-form Discovery of Stochastic Systems
Eshwar R A, Gajanan V. Honnavar
We present an algorithm for learning the governing equations of a stochastic dynamical system from trajectory data. It recovers interpretable symbolic expressions for both the drif…
