TreeHCA: Hindsight-Guided Exploration and Credit Assignment for Multi-Turn LLM Agents

Debajoy Mukherjee, Jeremy Carleton, Sushil Vemuri +2

Outcome-supervised group-relative policy optimization (GRPO) assigns the same advantage to every token in an LLM agent trajectory, leaving useful and unhelpful decisions undifferen…

EDATracer: An Agentic Framework for Large-Scale EDA Artifact Analysis

Phat Tieu, Sayanti Jana, Matthew DeLorenzo +5

Modern chip design relies on electronic design automation (EDA) tools that generate large, heterogeneous artifacts, including source files, scripts, logs, netlists, and reports. An…

EvoPlan: Evolutionary Neuro-Symbolic Robot Planning with Spatio-Temporal Guarantees

Bhavya Sai Nukapotula, Samin Moosavi, Haoze Wang +4

LLM-based robot planners are fluent but cannot guarantee that their plans are executable or safe. Classical PDDL planners can guarantee these properties, but only after the problem…

PITA: Preference-Guided Inference-Time Alignment for LLM Post-Training

Sarat Chandra Bobbili, Ujwal Dinesha, Dheeraj Narasimha +1

Inference-time alignment enables large language models (LLMs) to generate outputs aligned with end-user preferences without further training. Recent post-training methods achieve t…

Risk-Averse Finetuning of Large Language Models

Sapana Chaudhary, Ujwal Dinesha, Dileep Kalathil +1

We consider the challenge of mitigating the generation of negative or toxic content by the Large Language Models (LLMs) in response to certain prompts. We propose integrating risk-…

DOPL: Direct Online Preference Learning for Restless Bandits with Preference Feedback

Guojun Xiong, Ujwal Dinesha, Debajoy Mukherjee +2

Restless multi-armed bandits (RMAB) has been widely used to model constrained sequential decision making problems, where the state of each restless arm evolves according to a Marko…

CONGO: Compressive Online Gradient Optimization

Jeremy Carleton, Prathik Vijaykumar, Divyanshu Saxena +3

We address the challenge of zeroth-order online convex optimization where the objective function's gradient exhibits sparsity, indicating that only a small number of dimensions pos…
