From Noisy STEM to Crystal Structure: Evidence-Structure CoDiffusion under Composition Constraints

By directly resolving lattice periodicity and atomic columns, scanning transmission electron microscopy (STEM) offers rich structural cues, yet recovering a simulation-ready crystal structure from a single noisy STEM image remains an ill-posed inverse problem. In realistic acquisitions, corruption can obscure geometry-...

Symbolic-driven agentic reasoning for environmental and behavioral event detection

SDAR employs a symbolic reasoning engine to guide agentic decision making, connecting low-level visual cues with structured symbolic representations of events, and enables interpretable reasoning chains that capture causal relationships, contextual dependencies, and event categories.
