Self-attention summary networks for subsurface velocity-model building from common-image gathers

Shiqin Zeng, Yunlin Zeng, Abhinav Prakash Gahlot +2

Common-image gathers (CIGs) contain physically meaningful information about velocity-model errors through reflector focusing and residual moveout, but in conventional imaging workf…

HAWKEYE: Seeing One Layer Deeper -- A Cohesion-Aware Structural Channel for Temporal Link Prediction

Jiacheng Ding, Xiaofei Zhang

State-of-the-art temporal-link-prediction (TLP) models are, in essence, multi-channel information aggregators: they combine an interaction-history channel, a time-encoding channel,…

TGMS: An Agent-Native Bi-Temporal Graph Management System

Xiaofei Zhang

Temporal graph questions require reliable handling of time, identifiers, and arithmetic. Large language model (LLM) agents often fail on these tasks, especially when a graph record…
