In-Context Batch Black-box Optimization via Flow Matching

Quoc-Anh Hoang Nguyen, Xinyu Zhang, Daolang Huang +2

Batch black-box optimization is important for expensive systems where many candidates can be evaluated in parallel, yet only a few rounds of evaluation are affordable. In this regi…

Decoupled Conformal Optimisation: Efficient Prediction Sets via Independent Tuning and Calibration

Fanyi Wu, Lihua Niu, Samuel Kaski +1

Bayesian conformal optimisation methods often use the same held-out data both to search for efficient prediction sets and to certify coverage or risk. This coupling is natural for…

Elicitation-Augmented Bayesian Optimization

Alvar Haltia, Ville Hyvönen, Samuel Kaski

Human-in-the-loop Bayesian optimization (HITL BO) methods utilize human expertise to improve the sample-efficiency of BO. Most HITL BO methods assume that a domain expert can quant…

Online Sharp-Calibrated Bayesian Optimization

Marshal Arijona Sinaga, Julien Martinelli, Teemu Turpeinen +1

Bayesian optimization (BO) is a widely used framework for optimizing expensive black-box functions, commonly based on Gaussian process (GP) surrogate models. Its effectiveness reli…

Point-Identification of a Robust Predictor Under Latent Shift with Imperfect Proxies

Zahra Rahiminasab, Reza Soumi, Arto Klami +1

Addressing the domain adaptation problem becomes more challenging when distribution shifts across domains stem from latent confounders that affect both covariates and outcomes. Exi…

Bayesian Meta-Learning with Expert Feedback for Task-Shift Adaptation through Causal Embeddings

Lotta Mäkinen, Jorge Loría, Samuel Kaski

Meta-learning methods perform well on new within-distribution tasks but often fail when adapting to out-of-distribution target tasks, where transfer from source tasks can induce ne…

Bayesian Conformal Prediction as a Decision Risk Problem

Fanyi Wu, Veronika Lohmanova, Samuel Kaski +1

We propose Bayesian Conformal Prediction (BCP), a framework that combines Bayesian posterior predictive distributions with PAC-style conformal risk control to produce prediction se…
