Researchers have introduced Riemannian ICA (RICA), a new theoretical framework for understanding disentanglement in machine learning that moves beyond traditional generative models. RICA utilizes local geometric structure and Riemannian geometry to analyze factors of variation, offering a way to interpret disentangled features learned by modern pretrained encoders without relying on strong generative assumptions. The framework's core contribution is the disentanglement tensor, which quantifies a second-order notion of disentanglement and has shown success in recovering sources across various manifolds, outperforming standard ICA baselines.
