New bandit framework optimizes LLM configuration evaluation under budget constraints

Researchers have developed a new framework to address the challenges of evaluating large language model (LLM) configurations under budget constraints. This framework models the evaluation process as a cost-aware multi-objective bandit problem, where each configuration has an associated cost and produces a vector of outcomes. The proposed methods include a hypervolume-based UCB algorithm for online selection and a cost-aware empirical gap elimination algorithm for Pareto identification, both designed to optimize efficiency and accuracy within limited budgets. Experimental results on LLM configuration tasks show the effectiveness of this approach for efficient decision-making and identification of optimal configurations. AI
