PREBA: Surgical Duration Prediction via PCA-Weighted Retrieval-Augmented LLMs and Bayesian Averaging Aggregation

Researchers developed PREBA, a retrieval-augmented framework that uses PCA-weighted retrieval and Bayesian averaging to improve surgical duration prediction accuracy by up to 40% using large language models. The system grounds LLM predictions in institution-specific clinical data without requiring computationally intensive training, achieving performance competitive with supervised machine learning methods.

CUPID: A Plug-in Framework for Joint Aleatoric and Epistemic Uncertainty Estimation with a Single Model

Researchers introduce CUPID, a plug-in framework that estimates both aleatoric and epistemic uncertainty in deep learning models without requiring model retraining. The modular approach can be inserted into any layer of pretrained networks and provides interpretable uncertainty analysis for high-stakes AI applications.

Model Already Knows the Best Noise: Bayesian Active Noise Selection via Attention in Video Diffusion Model

Researchers propose ANSE, a new framework that improves video generation quality in diffusion models by intelligently selecting initial noise seeds based on the model's internal attention patterns. The method uses Bayesian uncertainty quantification to identify high-quality seeds that produce better video quality and temporal coherence with minimal computational overhead.
