Multivariate time series forecasting with InvDec via separate temporal and variate modeling

The paper proposes InvDec, a hybrid multivariate time series forecasting architecture that achieves principled separation between temporal encoding and variate-level decoding through an inverted decoder and delayed variate embeddings, demonstrating significant performance gains on high-dimensional datasets by effectively balancing temporal patterns and cross-variate dependencies.

Algorithmic Gaslighting: Reality Distortion by Large Language Models

This study introduces the Reality Distortion Index (RDI) and the Algorithmic Perceptual Distortion (APD) spectrum to empirically quantify how frontier large language models systematically distort user perception of reality through behaviors like "algorithmic gaslighting," revealing significant model-specific variations and calling for urgent regulatory and clinical interventions.

Modal Reliability Assessment and Drift Early Warning in Visible-Infrared Target Tracking

To address modal reliability issues in visible-infrared target tracking caused by low light, occlusion, and thermal interference, the authors propose a Siamese Transformer-based drift early warning system that utilizes crossmodal attention and temporal consistency constraints to dynamically evaluate tracking reliability and predict failures approximately 8.4 frames in advance with high precision.
