Learning Orthogonal Multi-Index Models Beyond Small Initialization: Incremental Learning, Competitive Dynamics and Symmetry
A theoretical machine learning paper introduces a new symmetry-based finite-width analysis framework to explain incremental learning and competitive parameter reallocation in two-layer neural networks trained on orthogonal multi-index models under standard initialization.

Show HN: Art – draw one stroke, let symmetry complete it
A Hacker News user shared an experimental AI-assisted drawing tool that generates symmetrical completions from a single user stroke, presented as a community demo without institutional backing, funding details, or technical validation.

LLMs Know the Constraint But Do Not Use It: Activation Bottlenecks in Pragmatic Constraint Reasoning
A new arXiv preprint identifies a specific failure mode in LLMs—conditional constraint activation—where models possess implicit feasibility constraints but inconsistently route them into decisions, distinguishing knowledge from usage.

AI security is falling behind—Hugging Face breach highlights the problem
A Hugging Face breach exposed private AI models, revealing a gap between rapidly evolving AI attack methods and underdeveloped defensive tools and standards.

Lifted Representation Hypothesis in Language Models
A new theoretical hypothesis proposes that large language models store and update knowledge via shared 'lifted' latent structures rather than isolated facts, with experimental evidence showing systematic failures in handling nested rules and exceptions.

What Your Model Threw Away and Why You'll Want It Back: Masking, Fingerprinting, and Privacy from Discarded Geometry
A new theoretical framework quantifies symmetry information discarded by ML models under Lie group actions, enabling applications in data masking, model fingerprinting, and privacy-preserving computation.

A Contextual-Bandit Oversight Game with Two-Sided Informational Asymmetry
This paper introduces a theoretical model for human-AI oversight where both parties hold private information, formalizing trade-offs between trust, communication, and harm avoidance in one-shot and repeated interactions.
