Explicit Regional Representations For Video Quality Assessment

End-to-end video quality assessment (VQA) methods leave the regional evidence underlying their predictions largely implicit. We introduce an explicit pixel-level regional representation for VQA, instantiated as a Quality-Relevance Heatmap (QRH) that combines localized degradation evidence with perceptual priors under v...

Follow the Perturbed Leader for Linear Bandits: $\sqrt{T}$ Regret over General Convex Sets

This work gives the first adversarial linear bandit algorithm based on Follow-the-Perturbed-Leader (FTPL) that achieves $\sqrt{T}$ regret over general convex action sets and develops a systematic way to analyze the stability term in the FTPL regret through the Fisher information of the perturbation distribution.
