A coupled-mechanisms modelling framework for neurodegeneration

no code implementations10 Aug 2023 Tiantian He, Elinor Thompson, Anna Schroder, Neil P. Oxtoby, Ahmed Abdulaal, Frederik Barkhof, Daniel C. Alexander

We account for the heterogeneity of disease by fitting the model at the individual level, allowing the epicenters and rate of progression to vary among subjects.

Not All Neighbors Are Worth Attending to: Graph Selective Attention Networks for Semi-supervised Learning

no code implementations14 Oct 2022 Tiantian He, Haicang Zhou, Yew-Soon Ong, Gao Cong

We further propose Graph selective attention networks (SATs) to learn representations from the highly correlated node features identified and investigated by different SA mechanisms.

Exploring Linear Feature Disentanglement For Neural Networks

no code implementations22 Mar 2022 Tiantian He, Zhibin Li, Yongshun Gong, Yazhou Yao, Xiushan Nie, Yilong Yin

Non-linear activation functions, e. g., Sigmoid, ReLU, and Tanh, have achieved great success in neural networks (NNs).

Learning Conjoint Attentions for Graph Neural Nets

1 code implementation NeurIPS 2021 Tiantian He, Yew-Soon Ong, Lu Bai

Given the novel Conjoint Attention strategies, we then propose Graph conjoint attention networks (CATs) that can learn representations embedded with significant latent features deemed by the Conjoint Attentions.
