Sliding-window beats linear attention

via Arxiv 👤 Alexia Jolicoeur-Martineau, Rhea Sanjay Sukthanker, Pashmina Cameron et al. 📅 2026-08-28
⚡ Score: 6.8
"Due to the nature of quadratic attention, Large Language Models (LLMs) consume a lot of memory and energy. Every new token costs more than the previous one. For each additional token, the keys and values must be stored in memory indefinitely, which is unsustainable. Several alternatives have been..."

⚡ Score: 6.7
"We investigate whether automatic speech recognition (ASR) errors in user input can lead to unsafe outputs from Embodied AI (EAI) models. We find that ASR errors can lead to harmful instructions being accepted and executed by EAI models, thereby reducing safety. We simulate ASR errors and combine the..."

Curvature-Conditioned Multiscale Momentum with Sphere Constraints for LLM Pretraining

via Arxiv 👤 Shuchen Zhu, Yuxin Fang, Mingze Wang et al. 📅 2026-08-28
⚡ Score: 6.6
"Pretraining accounts for a large fraction of the total computational cost in LLM training. However, noise-dominant gradients and the highly ill-conditioned loss landscape bring severe challenges. Although modern adaptive optimizers such as AdamW and Muon have achieved great success in large-scale pr..."
