Contextual Causal Bayesian Optimisation

arXiv:2301.12412v3 Announce Type: replace Abstract: We introduce a unified framework for contextual and causal Bayesian optimisation, which aims to design intervention policies maximising the expectation of a target variable. Our approach leverages both observed contextual information and known causal graph…

Enhanced geometry prediction in laser directed energy deposition using meta-learning

arXiv:2512.22241v1 Announce Type: new Abstract: Accurate bead geometry prediction in laser-directed energy deposition (L-DED) is often hindered by the scarcity and heterogeneity of experimental datasets collected under different materials, machine configurations, and process parameters. To address this challenge, a cross-dataset…

Fairness Evaluation of Risk Estimation Models for Lung Cancer Screening

arXiv:2512.22242v1 Announce Type: new Abstract: Lung cancer is the leading cause of cancer-related mortality in adults worldwide. Screening high-risk individuals with annual low-dose CT (LDCT) can support earlier detection and reduce deaths, but widespread implementation may strain the already limited…

Predicting Mycotoxin Contamination in Irish Oats Using Deep and Transfer Learning

arXiv:2512.22243v1 Announce Type: new Abstract: Mycotoxin contamination poses a significant risk to cereal crop quality, food safety, and agricultural productivity. Accurate prediction of mycotoxin levels can support early intervention strategies and reduce economic losses. This study investigates the use of…

Calibrating LLM Judges: Linear Probes for Fast and Reliable Uncertainty Estimation

arXiv:2512.22245v1 Announce Type: new Abstract: As LLM-based judges become integral to industry applications, obtaining well-calibrated uncertainty estimates efficiently has become critical for production deployment. However, existing techniques, such as verbalized confidence and multi-generation methods, are often either poorly calibrated or…
