Designing Search Space for Unbounded Bayesian Optimization via Transfer Learning

Published in Joint European Conference on Machine Learning and Knowledge Discovery in Databases, 2025

This paper introduces a transfer-learning-based Bayesian Optimization algorithm that automatically designs promising search spaces without needing prior knowledge, overcomes restrictive assumptions, and outperforms state-of-the-art methods across benchmarks.

Bayesian Optimization for Unknown Cost-Varying Variable Subsets with No-Regret Costs

Published in Proceedings of the AAAI Conference on Artificial Intelligence, 2025

We propose a new Bayesian Optimization algorithm that handles variable subsets with random and unknown costs, achieving sub-linear regret in both quality and cost, and outperforming baselines across benchmarks.
