STAG: Biologically guided spatial transcriptomics prediction via hypergraph learning

STAG is proposed, a dual-branch framework for gene-aware expression prediction and spatial context modeling that leverages gene semantic information as biological guidance by encoding gene names with a foundation model, enabling coordinated gene-aware interactions beyond independent gene prediction.

StateTrace: An Object-Centric Framework for Hidden-State Spatiotemporal Reasoning in Long Videos

StateTrace is proposed, a novel object-centric framework that endows VideoLLMs with an explicit mechanism for hidden state reasoning in long videos, and builds a reusable spatiotemporal state memory that organizes object trajectories, inter-object relations, and state-transition events into a structured reasoning subst...
