SBBTS: A Unified Schr\"odinger-Bass Framework for Synthetic Financial Time Series

cs.LG · 2026-04-08 · unverdicted · novelty 7.0

SBBTS creates a diffusion process that jointly models drift and stochastic volatility in financial time series via a tractable decomposition into conditional transport problems, recovering parameters missed by prior Schrödinger bridge methods and improving downstream ML performance on S&P 500 data.
