Enhancing Reinforcement Learning Fine-Tuning with an Online Refiner

arXiv:2603.18088v1 Announce Type: new Abstract: Constraints are essential for stabilizing reinforcement learning fine-tuning (RFT) and preventing degenerate outputs, yet they inherently conflict with the optimization objective because stronger constraints limit the ability of a fine-tuned model to discover better solutions.…

ARTEMIS: A Neuro Symbolic Framework for Economically Constrained Market Dynamics

arXiv:2603.18107v1 Announce Type: new Abstract: Deep learning models in quantitative finance often operate as black boxes, lacking interpretability and failing to incorporate fundamental economic principles such as no-arbitrage constraints. This paper introduces ARTEMIS (Arbitrage-free Representation Through Economic Models and Interpretable…

Weights to Code: Extracting Interpretable Algorithms from the Discrete Transformer

arXiv:2601.05770v2 Announce Type: replace Abstract: Algorithm extraction aims to synthesize executable programs directly from models trained on algorithmic tasks, enabling de novo algorithm discovery without relying on human-written code. However, applying this paradigm to Transformer is hindered by representation entanglement…

BoundAD: Boundary-Aware Negative Generation for Time Series Anomaly Detection

arXiv:2603.18111v1 Announce Type: new Abstract: Contrastive learning methods for time series anomaly detection (TSAD) heavily depend on the quality of negative sample construction. However, existing strategies based on random perturbations or pseudo-anomaly injection often struggle to simultaneously preserve temporal semantic…

Tula: Optimizing Time, Cost, and Generalization in Distributed Large-Batch Training

arXiv:2603.18112v1 Announce Type: new Abstract: Distributed training increases the number of batches processed per iteration either by scaling-out (adding more nodes) or scaling-up (increasing the batch-size). However, the largest configuration does not necessarily yield the best performance. Horizontal scaling introduces…

Transfer Learning for Neutrino Scattering: Domain Adaptation with GANs

arXiv:2508.12987v2 Announce Type: replace-cross Abstract: Transfer learning (TL) is used to extrapolate the physics information encoded in a Generative Adversarial Network (GAN) trained on synthetic neutrino-carbon inclusive scattering data to related processes such as neutrino-argon and antineutrino-carbon interactions. We investigate…
