Total Variation Distance Estimation in Autoregressive Models

Eric Price, Kevin Tian, Zhiyang Xun +1

Modern LLM deployments use a number of implementation choices and inference optimizations (e.g., batching, custom kernels, and quantization) on top of fixed weights, so two engines…

Query Lower Bounds for Diffusion Sampling

Zhiyang Xun, Eric Price

Diffusion models generate samples by iteratively querying learned score estimates. A rapidly growing literature focuses on accelerating sampling by minimizing the number of score e…

Posterior Sampling by Combining Diffusion Models with Annealed Langevin Dynamics

Zhiyang Xun, Shivam Gupta, Eric Price

Given a noisy linear measurement of a distribution , and a good approximation to the prior , when can we sample from the posterior ? Posterio…

Improved Sample Complexity Bounds for Diffusion Model Training

Shivam Gupta, Aditya Parulekar, Eric Price +1

Diffusion models have become the most popular approach to deep generative modeling of images, largely due to their empirical performance and reliability. From a theoretical standpo…

Diffusion Posterior Sampling is Computationally Intractable

Shivam Gupta, Ajil Jalal, Aditya Parulekar +2

Diffusion models are a remarkably effective way of learning and sampling from a distribution . In posterior sampling, one is also given a measurement model and…

Spectral Guarantees for Adversarial Streaming PCA

Eric Price, Zhiyang Xun

In streaming PCA, we see a stream of vectors and want to estimate the top eigenvector of their covariance matrix. This is easier if the spectral…
