Graph attention networks

open access: yesCoRR, 2017
We present graph attention networks (GATs), novel neural network architectures that operate on graph-structured data, leveraging masked self-attentional layers to address the shortcomings of prior methods based on graph convolutions or their approximations.

Molecular signatures of attention networks

open access: yesHuman Brain Mapping, 2023
Abstract Attention network theory proposes three distinct types of attention—alerting, orienting, and control—that are supported by separate brain networks and modulated by different neurotransmitters, that is, norepinephrine, acetylcholine, and dopamine.

Structured Attention Networks

open access: yesCoRR, 2017
Attention networks have proven to be an effective approach for embedding categorical inference within a deep neural network. However, for many tasks we may want to model richer structural dependencies without abandoning end-to-end training. In this work, we experiment with incorporating richer structural distributions, encoded using graphical models ...

Geometric Scattering Attention Networks

open access: yesICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021
Geometric scattering has recently gained recognition in graph representation learning, and recent work has shown that integrating scattering features in graph convolution networks (GCNs) can alleviate the typical oversmoothing of features in node representation learning.

A Regularized Attention Mechanism for Graph Attention Networks [PDF]

open access: yesICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020
Machine learning models that can exploit the inherent structure in data have gained prominence. In particular, there is a surge in deep learning solutions for graph-structured data, due to its wide-spread applicability in several fields. Graph attention networks (GAT), a recent addition to the broad class of feature learning models in graphs, utilizes ...

Attention to Emotional Information Is Associated With Cytokine Responses to Psychological Stress

open access: yesFrontiers in Neuroscience, 2018
This study aimed to investigate the impact of mental stress on salivary cytokines and attention to emotional stimuli, as well as associations between stress-induced changes of immune and cognitive parameters.

Modeling Graph Neural Networks and Dynamic Role Sorting for Argument Extraction in Documents

open access: yesApplied Sciences, 2023
The existing methods for document-level event extraction mainly face two challenges. The first challenge is effectively capturing event information that spans across sentences.

Hyperbolic Attention Networks

open access: yesCoRR, 2018
We introduce hyperbolic attention networks to endow neural networks with enough capacity to match the complexity of data with hierarchical and power-law structure. A few recent approaches have successfully demonstrated the benefits of imposing hyperbolic geometry on the parameters of shallow networks.

Attentional Networks in Parkinson’s Disease [PDF]

open access: yesBehavioural Neurology, 2013
We tested the efficiency of three attentional systems (spatial orienting, phasic alerting and executive control) in patients with Parkinson's disease (PD), by using a modified version of the Attention Network Test, which employs acoustic tones to modulate phasic alertness.

Imaging attention networks [PDF]

open access: yesNeuroImage, 2012
The study of attention has largely been about how to select among the various sensory events but also involves the selection among conflicting actions. Prior to the late 1980s, locating bottlenecks between sensory input and response dominated these studies, a different view was that attentional limits involved the importance of maintaining behavioral ...
