Query-Routed Activation Editing with Truth-hierarchical Preference Optimization

AAAI 2026technical

Hallucination has emerged as a pivotal challenge of Large Language Models (LLMs) that generate plausible yet non‑factual content, significantly impeding the trustworthy AI applications in real-world scenarios like medical diagnosis and autonomous driving. Editing the internal activations of LLMs du

RSTT: Real-Time Spatial Temporal Transformer for Space-Time Video Super-Resolution

CVPR 2022poster

Space-time video super-resolution (STVSR) is the task of interpolating videos with both Low Frame Rate (LFR) and Low Resolution (LR) to produce High-Frame-Rate (HFR) and also High-Resolution (HR) counterparts. The existing methods based on Convolutional Neural Network (CNN) succeed in achieving visu…
