Scalable Variational Bayesian Fine-Tuning of LLMs via Orthogonalized Low-Rank Adapters

arXiv:2604.03388v1 Announce Type: new Abstract: When deploying large language models (LLMs) to safety-critical applications, uncertainty quantification (UQ) is of utmost importance to self-assess the reliability of the LLM-based decisions. However, such decisions typically suffer from overconfidence, particularly after parameter-efficient fine-tuning…

Random-Bridges as Stochastic Transports for Generative Models

arXiv:2512.14190v3 Announce Type: replace Abstract: This paper motivates the use of random-bridges — stochastic processes conditioned to take target distributions at fixed timepoints — in the realm of generative modelling. Herein, random-bridges can act as stochastic transports between two probability…

Learning Sampled-data Control for Swarms via MeanFlow

arXiv:2603.20189v2 Announce Type: replace Abstract: Steering large-scale swarms with only limited control updates is often needed due to communication or computational constraints, yet most learning-based approaches do not account for this and instead model instantaneous velocity fields. As a result,…

Adaptive Threshold-Driven Continuous Greedy Method for Scalable Submodular Optimization

arXiv:2604.03419v1 Announce Type: new Abstract: Submodular maximization under matroid constraints is a fundamental problem in combinatorial optimization with applications in sensing, data summarization, active learning, and resource allocation. While the Sequential Greedy (SG) algorithm achieves only a $frac{1}{2}$-approximation due to…

Synthetic Sandbox for Training Machine Learning Engineering Agents

arXiv:2604.04872v1 Announce Type: cross Abstract: As large language model agents advance beyond software engineering (SWE) tasks toward machine learning engineering (MLE), verifying agent behavior becomes orders of magnitude more expensive: while SWE tasks can be verified via fast-executing unit tests,…
