Convolutional neural networks (CNNs) have succeeded in many practical applications.

Distributionally Robust Semi-Supervised Learning Over Graphs

no code implementations20 Oct 2021 Alireza Sadeghi, Meng Ma, Bingcong Li, Georgios B. Giannakis

The data distribution is considered unknown, but lies within a Wasserstein ball centered around empirical data distribution.

RAGA: Relation-aware Graph Attention Networks for Global Entity Alignment

2 code implementations1 Mar 2021 Renbo Zhu, Meng Ma, Ping Wang

Entity alignment (EA) is the task to discover entities referring to the same real-world object from different knowledge graphs (KGs), which is the most crucial step in integrating multi-source KGs.

A Bidirectional Tree Tagging Scheme for Joint Medical Relation Extraction

no code implementations31 Aug 2020 Xukun Luo, Weijie Liu, Meng Ma, Ping Wang

In this paper, inspired by the tree-like relation structures in the medical text, we propose a novel scheme called Bidirectional Tree Tagging (BiTT) to form the medical relation triples into two two binary trees and convert the trees into a word-level tags sequence.

On the Convergence of SARAH and Beyond

no code implementations5 Jun 2019 Bingcong Li, Meng Ma, Georgios B. Giannakis

For convex problems, when adopting an $n$-dependent step size, the complexity of L2S is ${\cal O}(n+ \sqrt{n}/\epsilon)$; while for more frequently adopted $n$-independent step size, the complexity is ${\cal O}(n+ n/\epsilon)$.

Kernel-based Inference of Functions over Graphs

no code implementations28 Nov 2017 Vassilis N. Ioannidis, Meng Ma, Athanasios N. Nikolakopoulos, Georgios B. Giannakis, Daniel Romero

The study of networks has witnessed an explosive growth over the past decades with several ground-breaking methods introduced.

Kernel-based Reconstruction of Graph Signals

no code implementations23 May 2016 Daniel Romero, Meng Ma, Georgios B. Giannakis

A number of SPoG notions such as bandlimitedness, graph filters, and the graph Fourier transform are naturally accommodated in the kernel framework.
