New PVMC method speeds up deep state space model training

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 1 source

Researchers have developed a new training method called parallel variational Monte Carlo (PVMC) for deep state space models (DSSMs). This approach bridges the gap between auto-encoding and sequential Monte Carlo (SMC) methods, enabling robust training for both generative and discriminative tasks. PVMC demonstrates state-of-the-art results and achieves training speeds ten times faster than existing SMC techniques. AI

Efficient Learning of Deep State Space Models via Importance Smoothing

Latent state space systems are ubiquitous in statistical modelling, arising naturally when a time series is observed through a noisy measurement function, however training deep state space models (DSSM) at scale remains difficult. Two largely distinct strategies and literatures h…
