Flow Map Learning via Nongradient Vector Flow

Mark Goldstein, Anshuk Uppal, Raghav Singhal +2

Diffusion and flow-based models benefit from simple regression losses, but inference incurs significant overhead because sampling requires integration. Consistency models address t…

Rethinking Reasoning with MDLMs: Early Exits, Post-hoc Reasoning, and Beyond

Zachary Horvitz, Raghav Singhal, Hao Zou +4

The reasoning paradigm, where language models reason before answering, has enabled breakthroughs on tasks such as mathematical problem-solving. While current tooling for reasoning…

A General Framework for Inference-time Scaling and Steering of Diffusion Models

Raghav Singhal, Zachary Horvitz, Ryan Teehan +4

Diffusion models produce impressive results in modalities ranging from images and video to protein design and text. However, generating samples with user-specified properties remai…

What's the score? Automated Denoising Score Matching for Nonlinear Diffusions

Raghav Singhal, Mark Goldstein, Rajesh Ranganath

Reversing a diffusion process by learning its score forms the heart of diffusion-based generative modeling and for estimating properties of scientific systems. The diffusion proces…

Adaptive Sampling of k-Space in Magnetic Resonance for Rapid Pathology Prediction

Chen-Yu Yen, Raghav Singhal, Umang Sharma +3

Magnetic Resonance (MR) imaging, despite its proven diagnostic utility, remains an inaccessible imaging modality for disease surveillance at the population level. A major factor re…

Comprehensive study of forced convection over a heated elliptical cylinder with varying angle of incidences to uniform free stream

Raghav Singhal, Sailen Dutta, Jiten C. Kalita

In this paper we carry out a numerical investigation of forced convection heat transfer from a heated elliptical cylinder in a uniform free stream with angle of inclination $θ^{\ci…

Where to Diffuse, How to Diffuse, and How to Get Back: Automated Learning for Multivariate Diffusions

Raghav Singhal, Mark Goldstein, Rajesh Ranganath

Diffusion-based generative models (DBGMs) perturb data to a target noise distribution and reverse this process to generate samples. The choice of noising process, or inference diff…

An efficient explicit jump HOC immersed interface approach for transient incompressible viscous flows

Raghav Singhal, Jiten C Kalita

In the present work, we propose a novel hybrid explicit jump immersed interface approach in conjunction with a higher order compact (HOC) scheme for simulating transient complex fl…

Kernelized Complete Conditional Stein Discrepancy

Raghav Singhal, Xintian Han, Saad Lahlou +1

Much of machine learning relies on comparing distributions with discrepancy measures. Stein's method creates discrepancy measures between two distributions that require only the un…
