Finite Evidence, Infinite Horizons: The Artificial Age Score as a Case Study in Longitudinal AI Measurement

This paper argues that finite longitudinal AI evaluation records, exemplified by the Artificial Age Score (AAS), cannot determine infinite-horizon system properties or convergence without explicit stipulated continuation models, as demonstrated through counterexamples and stress tests showing that bounded observations alone yield only conditional, model-based inferences rather than definitive conclusions.

Weakly Supervised Anomaly Detection and Privacy Risk Scoring in Community Message Threads

This paper introduces RiskThread-LF, a weakly supervised and privacy-preserving framework that detects anomalous community message threads by fusing diverse behavioral signals and correcting for reporting bias, achieving superior performance over content-based and graph-based baselines while maintaining robustness under differential privacy.

Risk-Aware Adaptive Video Processing with Freshness Control for Low-Latency Assistive Vision

This paper proposes a risk-aware adaptive video-processing controller for low-latency assistive vision that dynamically separates frame admission from inference-mode selection based on network, compute, and navigation risk metrics, thereby significantly reducing end-to-end latency and shedding stale non-critical frames while ensuring critical-risk observations receive full-fidelity processing.

A Global–Local Feature Coupled Invertible Neural Network with Multi-Channel Attention Pooling for Image Steganography

This paper proposes CINN, a convolution-based invertible neural network that integrates global-local feature coupling and multi-channel attention pooling to simultaneously enhance the security, imperceptibility, and recovery fidelity of image steganography, outperforming existing state-of-the-art methods across multiple datasets and steganalysis evaluations.
