Node-Adaptive Regularization for Graph Signal Reconstruction

open access: yesIEEE Open Journal of Signal Processing, 2021
A critical task in graph signal processing is to estimate the true signal from noisy observations over a subset of nodes, also known as the reconstruction problem.

Fusion of Radiomics and Gated Graph Attention Network for Pulmonary Nodule Malignancy Classification [PDF]

open access: yesJournal of Imaging
Pulmonary nodule malignancy classification requires effective integration of heterogeneous imaging features and contextual information among nodules. Existing models mainly analyze nodules independently and may overlook inter-nodule relationships.

On the Multiplicative Regularization of Graph Laplacians on Closed and Open Structures With Applications to Spectral Partitioning [PDF]

open access: yesIEEE Access, 2014
A new regularization technique for graph Laplacians arising from triangular meshes of closed and open structures is presented. The new technique is based on the analysis of graph Laplacian spectrally equivalent operators in terms of Sobolev norms and on ...

Spectral Geometry for Structural Pattern Recognition [PDF]

open access: yes, 2010
Graphs are used pervasively in computer science as representations of data with a network or relational structure, where the graph structure provides a flexible representation such that there is no fixed dimensionality for objects. However, the analysis

Catastrophic Forgetting in Deep Graph Networks: A Graph Classification Benchmark

open access: yesFrontiers in Artificial Intelligence, 2022
In this work, we study the phenomenon of catastrophic forgetting in the graph representation learning scenario. The primary objective of the analysis is to understand whether classical continual learning techniques for flat and sequential data have a ...

Semisupervised Hyperspectral Image Classification via Superpixel-Based Graph Regularization With Local and Nonlocal Features

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Although a graph-based semisupervised learning (SSL) approach can utilize limited numbers of labeled samples for hyperspectral image (HSI) classification, it is difficult to use the large amount of pixels in an HSI to construct a large-scale graph.
