Large-Scale Semi-Supervised Learning via Graph Structure Learning over High-Dense Points
Zitong Wang, Li Wang, Raymond Chan +1
We focus on developing a novel scalable graph-based semi-supervised learning (SSL) method for a small number of labeled data and a large amount of unlabeled data. Due to the lack o…
A Two-stage Classification Method for High-dimensional Data and Point Clouds
Xiaohao Cai, Raymond Chan, Xiaoyu Xie +1
High-dimensional data classification is a fundamental task in machine learning and imaging science. In this paper, we propose a two-stage multiphase semi-supervised classification…
Total Variation and Tight Frame Image Segmentation with Intensity Inhomogeneity
Raymond Chan, Hongfei Yang, Tieyong Zeng
Image segmentation is an important task in the domain of computer vision and medical imaging. In natural and medical images, intensity inhomogeneity, i.e. the varying image intensi…
One-Dimensional Phase Retrieval: Regularization, Box Relaxation and Uniqueness
Wing Hong Wong, Yifei Lou, Stefano Marchesini +1
Recovering a signal from its Fourier magnitude is referred to as phase retrieval, which occurs in different fields of engineering and applied physics. This paper gives a new charac…
