Hyperparameter Estimation for Sparse Bayesian Learning Models

no code implementations4 Jan 2024 Feng Yu, Lixin Shen, Guohui Song

Sparse Bayesian Learning (SBL) models are extensively used in signal processing and machine learning for promoting sparsity through hierarchical priors.

Sequential edge detection using joint hierarchical Bayesian learning

no code implementations28 Feb 2023 Yao Xiao, Anne Gelb, Guohui Song

This paper introduces a new sparse Bayesian learning (SBL) algorithm that jointly recovers a temporal sequence of edge maps from noisy and under-sampled Fourier data.

PCM-TV-TFV: A Novel Two Stage Framework for Image Reconstruction from Fourier Data

no code implementations29 May 2017 Weihong Guo, Guohui Song, Yue Zhang

We propose in this paper a novel two-stage Projection Correction Modeling (PCM) framework for image reconstruction from (non-uniform) Fourier measurements.
