AISTATS 2025, ACL 2024 Workshop on Privacy in Natural Language Processing2025Large Language Models (LLMs) have seen widespread adoption due to their remarkable natural language capabilities. However, when deploying them in real-world settings, it is important to align LLMs to generate texts according to acceptable human standards. Methods such as Proximal Policy Optimization (PPO) and Direct Preference Optimization (DPO) have enabled significant progress in refining LLMs using human

2025As large language models (LLMs) become increasingly versatile, numerous large scale benchmarks have been developed to thoroughly assess their capabilities. These benchmarks typically consist of diverse datasets and prompts to evaluate different aspects of LLM performance. However, comprehensive evaluations on hundreds or thousands of prompts incur tremendous costs in terms of computation, money, and time

2025In this paper, we study the problem of estimation and learning under temporal distribution shift. Consider an observation sequence of length n, which is a noisy realization of a time-varying ground-truth sequence. Our focus is to develop methods to estimate the ground-truth at the final time-step while providing sharp point-wise estimation error rates. We show that, without prior knowledge on the level

2025Can we efficiently choose the best Anomaly Detection (AD) algorithm for a data-stream without requiring anomaly labels? Streaming anomaly detection is hard. SOTA AD algorithms are sensitive to their hyper-parameters and no single method works well on all datasets. The best algorithm/hyper-parameter combination for a given data-stream can change over time with data drift. ‘What is an anomaly?’ is often application

2025In Amazon robotic warehouses, the destination-to-chute mapping problem is crucial for efficient package sorting. Often, however, this problem is complicated by uncertain and dynamic package induction rates, which can lead to increased package recirculation. To tackle this challenge, we introduce a Distributionally Robust Multi-Agent Reinforcement Learning (DRMARL) framework that learns a destination-to-chute
