Discretized Approximate Ancestral Sampling
Alfredo De la Fuente, Saurabh Singh, Jona Ballé
The Fourier Basis Density Model (FBM) was recently introduced as a flexible probability model for band-limited distributions, i.e. ones which are smooth in the sense of having a ch…

Stochastic Sampling from Deterministic Flow Models
Saurabh Singh, Ian Fischer
Deterministic flow models, such as rectified flows, offer a general framework for learning a deterministic transport map between two distributions, realized as the vector field for…
