OmniCast: A Masked Latent Diffusion Model for Weather Forecasting Across Time Scales

NeurIPS 2025poster

Accurate weather forecasting across time scales is critical for anticipating and mitigating the impacts of climate change. Recent data-driven methods based on deep learning have achieved significant success in the medium range, but struggle at longer subseasonal-to-seasonal (S2S) horizons due to err…

Sparsity-Inducing Categorical Prior Improves Robustness of the Information Bottleneck

AISTATS 2023poster

The information bottleneck framework provides a systematic approach to learning representations that compress nuisance information in the input and extract semantically meaningful information about predictions. However, the choice of a prior distribution that fixes the dimensionality across all the…
