arXiv:2606.07134v1 Announce Type: new Abstract: Information-theoretic acquisition functions such as Entropy Search (ES) offer a principled exploration-exploitation framework for Bayesian optimization (BO). However, their practical implementation relies on complicated and slow approximations, i.e., a Monte Carlo estimation of the information gain. This complexity can introduce numerical errors and requires specialized, hand-crafted implementations. We propose a two-stage amortization strategy that learns to approximate entropy search-based acquisition functions using Prior-data Fitted Networks
The increasing computational demands of complex AI models and the need for more efficient optimization techniques are driving research into faster and more robust inference methods.
This development could significantly accelerate the research and deployment of advanced AI applications that rely on efficient information-theoretic acquisition functions, reducing computational bottlenecks and development costs.
The reliance on slow and numerically complex Monte Carlo estimations for entropy search in Bayesian optimization is decreased, replaced by a faster, learned approximation.
