History Rhymes: Macro-Contextual Retrieval for Robust Financial Forecasting

arXiv:2511.09754v1 Announce Type: new Abstract: Financial markets are inherently non-stationary: structural breaks and macroeconomic regime shifts often cause forecasting models to fail when deployed out of distribution (OOD). Conventional multimodal approaches that simply fuse numerical indicators and textual sentiment rarely…

ELECTRA: A Cartesian Network for 3D Charge Density Prediction with Floating Orbitals

arXiv:2503.08305v3 Announce Type: replace Abstract: We present the Electronic Tensor Reconstruction Algorithm (ELECTRA) – an equivariant model for predicting electronic charge densities using floating orbitals. Floating orbitals are a long-standing concept in the quantum chemistry community that promises more compact…

Is nasty noise actually harder than malicious noise?

arXiv:2511.09763v1 Announce Type: new Abstract: We consider the relative abilities and limitations of computationally efficient algorithms for learning in the presence of noise, under two well-studied and challenging adversarial noise models for learning Boolean functions: malicious noise, in which an…

Hail to the Thief: Exploring Attacks and Defenses in Decentralised GRPO

arXiv:2511.09780v1 Announce Type: new Abstract: Group Relative Policy Optimization (GRPO) has demonstrated great utilization in post-training of Large Language Models (LLMs). In GRPO, prompts are answered by the model and, through reinforcement learning, preferred completions are learnt. Owing to the…
