Statistical Inference of Optimal Allocations I: Regularities and their Implications

no code implementations27 Mar 2024 Kai Feng, Han Hong

Moreover, leveraging profound insights from geometric functional analysis on convex and local Lipschitz functionals, we obtain additional generic Fr\'echet differentiability results for the value functions of optimal allocation problems.

Degradation-Noise-Aware Deep Unfolding Transformer for Hyperspectral Image Denoising

no code implementations6 May 2023 Haijin Zeng, JieZhang Cao, Kai Feng, Shaoguang Huang, Hongyan zhang, Hiep Luong, Wilfried Philips

However, model-based approaches rely on hand-crafted priors and hyperparameters, while learning-based methods are incapable of estimating the inherent degradation patterns and noise distributions in the imaging procedure, which could inform supervised learning.

Sparse Regularized Correlation Filter for UAV Object Tracking with adaptive Contextual Learning and Keyfilter Selection

no code implementations7 May 2022 Zhangjian Ji, Kai Feng, Yuhua Qian, Jiye Liang

Another approaches can alleviate the temporal degeneration of learned filters by introducing the temporal regularizer, which depends on the assumption that the filers between consecutive frames should be coherent.
