Clinical Intent Extraction: A FHIR-Aligned Representation and the CIRCA Benchmark

This work introduces Clinical Intent Extraction (CIE), the task of recovering these actions as complete structured rec-ords, and the Clinical Intent Representation (CIR), which decomposes each action into its verb, type, coded target, timing, and condition.

Safety-oriented pedestrian trajectory prediction at urban intersections using time-to-collision and crossing-zone context

The results indicate that safety-oriented training and structured integration of interaction and contextual information can reduce large trajectory-prediction errors, although broader validation across pedestrians, sites, and datasets is required.

Modeling Normal Is All You Need: Joint Latent Clustering for Anomaly Detection in Multimodal Cyber-Physical Systems

The detector, LatAD, jointly learns a latent and a Gaussian-mixture clustering of these regimes (VaDE) and scores anomalies by density rather than reconstruction, factorizing that density over correlation-community subsystems and combining per-community surprises by a cohesion-weighted, sparsity-adaptive statistic.
