Researchers have developed Compressed Active Subspaces (CAS), a novel method to make Bayesian inference more scalable for large models. Traditional active subspace methods require significant memory for model gradients, limiting their application to smaller models. CAS addresses this by first mapping model parameters to a compressed space using an isometric embedding, then constructing the active subspace within this reduced space. This approach substantially decreases memory requirements, enabling Bayesian inference for large neural networks while preserving predictive performance and uncertainty estimates. AI
