Provable Guarantees for Generative Behavior Cloning: Bridging Low-Level Stability and High-Level Behavior

Adam Block, Ali Jadbabaie, Daniel Pfrommer +2

We propose a theoretical framework for studying behavior cloning of complex expert demonstrations using generative modeling. Our framework invokes low-level controllers - either le…

Efficient Model-Free Exploration in Low-Rank MDPs

Zakaria Mhammedi, Adam Block, Dylan J. Foster +1

A major challenge in reinforcement learning is to develop practical, sample-efficient algorithms for exploration in high-dimensional domains where generalization and function appro…

Oracle-Efficient Smoothed Online Learning for Piecewise Continuous Decision Making

Adam Block, Alexander Rakhlin, Max Simchowitz

Smoothed online learning has emerged as a popular framework to mitigate the substantial loss in statistical and computational complexity that arises when one moves from classical t…

The Sample Complexity of Approximate Rejection Sampling with Applications to Smoothed Online Learning

Adam Block, Yury Polyanskiy

Suppose we are given access to independent samples from distribution and we wish to output one of them with the goal of making the output distributed as close as possible t…

Smoothed Online Learning for Prediction in Piecewise Affine Systems

Adam Block, Max Simchowitz, Russ Tedrake

The problem of piecewise affine (PWA) regression and planning is of foundational importance to the study of online learning, control, and robotics, where it provides a theoreticall…

Efficient and Near-Optimal Smoothed Online Learning for Generalized Linear Functions

Adam Block, Max Simchowitz

Due to the drastic gap in complexity between sequential and batch statistical learning, recent work has studied a smoothed sequential learning setting, where Nature is constrained…

Rate of convergence of the smoothed empirical Wasserstein distance

Adam Block, Zeyu Jia, Yury Polyanskiy +1

Consider an empirical measure induced by iid samples from a -dimensional -subgaussian distribution and let be the isotropic…

Counterfactual Learning To Rank for Utility-Maximizing Query Autocompletion

Adam Block, Rahul Kidambi, Daniel N. Hill +2

Conventional methods for query autocompletion aim to predict which completed query a user will select from a list. A shortcoming of this approach is that users often do not know wh…

Smoothed Online Learning is as Easy as Statistical Learning

Adam Block, Yuval Dagan, Noah Golowich +1

Much of modern learning theory has been split between two regimes: the classical offline setting, where data arrive independently, and the online setting, where data arrive adversa…

Intrinsic Dimension Estimation Using Wasserstein Distances

Adam Block, Zeyu Jia, Yury Polyanskiy +1

It has long been thought that high-dimensional data encountered in many practical machine learning tasks have low-dimensional structure, i.e., the manifold hypothesis holds. A natu…

Majorizing Measures, Sequential Complexities, and Online Learning

Adam Block, Yuval Dagan, Sasha Rakhlin

We introduce the technique of generic chaining and majorizing measures for controlling sequential Rademacher complexity. We relate majorizing measures to the notion of fractional c…

Fast Mixing of Multi-Scale Langevin Dynamics under the Manifold Hypothesis

Adam Block, Youssef Mroueh, Alexander Rakhlin +1

Recently, the task of image generation has attracted much attention. In particular, the recent empirical successes of the Markov Chain Monte Carlo (MCMC) technique of Langevin Dyna…

Generative Modeling with Denoising Auto-Encoders and Langevin Sampling

Adam Block, Youssef Mroueh, Alexander Rakhlin

We study convergence of a generative modeling method that first estimates the score function of the distribution using Denoising Auto-Encoders (DAE) or Denoising Score Matching (DS…
