Researchers propose spherical flows for improved categorical data sampling

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 2 sources

Researchers have developed a new method for learning generative models of discrete sequences by operating on a sphere instead of Euclidean space. This approach utilizes the von Mises-Fisher distribution to create a natural noise process and allows for both ODE and predictor-corrector sampling techniques. The method showed significant improvements in experiments involving Sudoku and language modeling tasks. AI

    We study the problem of learning generative models for discrete sequences in a continuous embedding space. Whereas prior approaches typically operate in Euclidean space or on the probability simplex, we instead work on the sphere $\mathbb S^{d-1}$. There the von Mises-Fisher (vMF…
