NetFormer: An interpretable model for recovering dynamical connectivity in neuronal population dynamics

ICLR 2025spotlight

Neuronal dynamics are highly nonlinear and nonstationary. Traditional methods for extracting the underlying network structure from neuronal activity recordings mainly concentrate on modeling static connectivity, without accounting for key nonstationary aspects of biological neural systems, such as o…

Query-Focused Retrieval Heads Improve Long-Context Reasoning and Re-ranking

EMNLP 2025

Recent work has identified retrieval heads (Wu et al., 2025), a subset of attention heads responsible for retrieving salient information in long-context language models (LMs), as measured by their copy-paste behavior in Needle-in-a-Haystack tasks. In this paper, we introduce QRHead (Query-Focused Re
