Time-varying graph representation learning via higher-order skip-gram with negative sampling

open access: yesEPJ Data Science, 2022
Representation learning models for graphs are a successful family of techniques that project nodes into feature spaces that can be exploited by other machine learning algorithms.

Improving the Robustness of GraphSAINT via Stability Training

open access: yesParadigmPlus, 2021
Graph Neural Networks (GNNs) field has a dramatic development nowadays due to the strong representation capabilities for data in non-Euclidean space, such as graph data.

Node copying: A random graph model for effective graph sampling

open access: yesSignal Processing, 2022
There has been an increased interest in applying machine learning techniques on relational structured-data based on an observed graph. Often, this graph is not fully representative of the true relationship amongst nodes. In these settings, building a generative model conditioned on the observed graph allows to take the graph uncertainty into account ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Sampling Graph Signals with Sparse Dictionary Representation

open access: yes, 2021
Graph sampling strategies require the signal to be relatively sparse in an alternative domain, e.g. bandlimitedness for reconstructing the signal. When such a condition is violated or its approximation demands a large bandwidth, the reconstruction often ...

Weighted Edge Sampling for Static Graphs

open access: yesInternational Journal of Data Mining, Modelling and Management, 2023
Graph Sampling provides an efficient yet inexpensive solution for analyzing large graphs. While extracting small representative subgraphs from large graphs, the challenge is to capture the properties of the original graph. Several sampling algorithms have been proposed in previous studies, but they lack in extracting good samples.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Graph Vertex Sampling with Arbitrary Graph Signal Hilbert Spaces

open access: yes, 2020
International audienceGraph vertex sampling set selection aims at selecting a set of ver-tices of a graph such that the space of graph signals that can be reconstructed exactly from those samples alone is maximal.

Empirical Characterization of Graph Sampling Algorithms

open access: yesSocial Network Analysis and Mining, 2022
Abstract Graph sampling allows mining a small representative subgraph from a big graph. Sampling algorithms deploy different strategies to replicate the properties of a given graph in the sampled graph. In this study, we provide a comprehensive empirical characterization of five graph sampling algorithms on six properties of a graph including ...
