LLM Query Scheduling with Prefix Reuse and Latency Constraints

NeurIPS 2025poster

The efficient deployment of large language models (LLMs) in online settings requires optimizing inference performance under stringent latency constraints, particularly the time-to-first-token (TTFT) and time-per-output-token (TPOT). This paper focuses on the query scheduling problem for LLM inferenc…

A Precise Characterization of SGD Stability Using Loss Surface Geometry

ICLR 2024poster

Stochastic Gradient Descent (SGD) stands as a cornerstone optimization algorithm with proven real-world empirical successes but relatively limited theoretical understanding. Recent research has illuminated a key factor contributing to its practical efficacy: the implicit regularization it instigates…

Sketching Algorithms for Sparse Dictionary Learning: PTAS and Turnstile Streaming

NeurIPS 2023poster

Sketching algorithms have recently proven to be a powerful approach both for designing low-space streaming algorithms as well as fast polynomial time approximation schemes (PTAS). In this work, we develop new techniques to extend the applicability of sketching-based approaches to the sparse dictiona…

On the Convergence of Inexact Predictor-Corrector Methods for Linear Programming

ICML 2022oral

Interior point methods (IPMs) are a common approach for solving linear programs (LPs) with strong theoretical guarantees and solid empirical performance. The time complexity of these methods is dominated by the cost of solving a linear system of equations at each iteration. In common applications of…

Inverse Reinforcement Learning in a Continuous State Space with Formal Guarantees

NeurIPS 2021poster

Inverse Reinforcement Learning (IRL) is the problem of finding a reward function which describes observed/known expert behavior. The IRL setting is remarkably useful for automated control, in situations where the reward function is difficult to specify manually or as a means to extract agent prefer…
