Knowledge graph augmentation: consistency, immutability, reliability, and context [PDF]

open access: yesPeerJ Computer Science, 2023
A knowledge graph is convenient for storing knowledge in artificial intelligence applications. On the other hand, it has some shortcomings that need to be improved.

G-CutMix: A CutMix-based graph data augmentation method for bot detection in social networks. [PDF]

open access: yesPLoS ONE
The CutMix technique is a sophisticated approach for augmenting data in order to train neural network-based image classifiers. Essentially, it involves cutting out a portion of a random image and pasting it into the same location as another image ...

Geometric Biplane Graphs II: Graph Augmentation [PDF]

open access: yesGraphs and Combinatorics, 2015
We study biplane graphs drawn on a finite point set $S$ in the plane in general position. This is the family of geometric graphs whose vertex set is $S$ and which can be decomposed into two plane graphs. We show that every sufficiently large point set admits a 5-connected biplane graph and that there are arbitrarily large point sets that do not admit ...

Graph Augmentation Learning

open access: yesCompanion Proceedings of the Web Conference 2022, 2022
Graph Augmentation Learning (GAL) provides outstanding solutions for graph learning in handling incomplete data, noise data, etc. Numerous GAL methods have been proposed for graph-based applications such as social network analysis and traffic flow forecasting. However, the underlying reasons for the effectiveness of these GAL methods are still unclear.

Few-Shot Charge Prediction with Data Augmentation and Feature Augmentation

open access: yesApplied Sciences, 2021
The task of charge prediction is to predict the charge based on the fact description. Existing methods have a good effect on the prediction of high-frequency charges, but the prediction of low-frequency charges is still a challenge. Moreover, there exist

Graph contrastive learning with implicit augmentations

open access: yesNeural Networks, 2023
Existing graph contrastive learning methods rely on augmentation techniques based on random perturbations (e.g., randomly adding or dropping edges and nodes). Nevertheless, altering certain edges or nodes can unexpectedly change the graph characteristics, and choosing the optimal perturbing ratio for each dataset requires onerous manual tuning. In this

Joint data and feature augmentation for self-supervised representation learning on point clouds

open access: yesGraphical Models, 2023
To deal with the exhausting annotations, self-supervised representation learning from unlabeled point clouds has drawn much attention, especially centered on augmentation-based contrastive methods.
