FLUID framework offers unified inference for complex dynamical systems

Researchers have introduced FLUID, a novel flow-based framework designed for amortized inference in high-dimensional nonlinear dynamical systems. This approach encodes observation histories into fixed-dimensional summary statistics, enabling the learning of both forward and backward flows for filtering and smoothing distributions. FLUID's architecture allows for extrapolation beyond training horizons and offers implicit regularization for improved trajectory smoothing, with experiments confirming its accuracy in approximating filtering and smoothing paths.
