Researchers have developed Triangular-Reference Schrödinger Bridges for Time Series (TR-SBTS), an advanced framework for time series generation. This method extends existing Schrödinger Bridges by replacing the standard Brownian reference with an intervalwise frozen diffusion reference that is triangular across multiple latent volatility levels. The approach involves a single entropy projection on an augmented state space, with variational constraints applied jointly across time and latent levels. The paper details the construction of TR-SBTS through a finite-dimensional conditioning map and evaluates its performance on numerical experiments. AI
