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 hyperspherical geometry of CLIP's semantic embedding space compared to traditional Gaussian assumptions. The proposed approach uses an Expectation-Maximization algorithm to identify semantic concepts within the latent space, improving performance in tasks like long-tailed and out-of-distribution detection.
