New E2M algorithm enhances tensor-based density estimation
Researchers have developed a new expectation-maximization (EM) algorithm called E$^2$M for tensor-based discrete density estimation. This algorithm addresses challenges with traditional $\alpha$-divergence methods by fi…

New model captures hyperspherical geometry of CLIP latent space
Researchers have developed a new probabilistic model for understanding the latent space of CLIP, a language-image pretraining model. This model, based on Mixtures of von Mises-Fisher distributions, better captures the h…

New TabSODA method improves survey data imputation with skip detection
Researchers have developed TabSODA, a new diffusion-based imputation method designed to handle missing data in large-scale surveys more effectively. This method addresses two key challenges: structural skips in question…
