Interpretable Sparsification of Brain Graphs: Better Practices and Effective Designs for Graph Neural Networks

1 code implementation26 Jun 2023 Gaotang Li, Marlena Duda, Xiang Zhang, Danai Koutra, Yujun Yan

Based on these insights, we propose a new model, Interpretable Graph Sparsification (IGS), which enhances graph classification performance by up to 5. 1% with 55. 0% fewer edges.

Learning low-dimensional dynamics from whole-brain data improves task capture

no code implementations18 May 2023 Eloy Geenjaar, Donghyun Kim, Riyasat Ohib, Marlena Duda, Amrit Kashyap, Sergey Plis, Vince Calhoun

We evaluate our approach on various task-fMRI datasets, including motor, working memory, and relational processing tasks, and demonstrate that it outperforms widely used dimensionality reduction techniques in how well the latent timeseries relates to behavioral sub-tasks, such as left-hand or right-hand tapping.
