Adaptive Weighted Co-Learning for Cross-Domain Few-Shot Learning

no code implementations6 Dec 2023 Abdullah Alchihabi, Marzi Heidari, Yuhong Guo

Due to the availability of only a few labeled instances for the novel target prediction task and the significant domain shift between the well annotated source domain and the target domain, cross-domain few-shot learning (CDFSL) induces a very challenging adaptation problem.

Efficient Low-Rank GNN Defense Against Structural Attacks

no code implementations18 Sep 2023 Abdullah Alchihabi, Qing En, Yuhong Guo

As a result, instead of using the dense adjacency matrix directly, ELR-GNN can learn a low-rank and sparse estimate of it in a simple, efficient and easy to optimize manner.

GDM: Dual Mixup for Graph Classification with Limited Supervision

no code implementations18 Sep 2023 Abdullah Alchihabi, Yuhong Guo

In this work, we propose a novel mixup-based graph augmentation method, Graph Dual Mixup (GDM), that leverages both functional and structural information of the graph instances to generate new labeled graph samples.

On the Brain Networks of Complex Problem Solving

no code implementations10 Oct 2018 Abdullah Alchihabi, Omer Ekmekci, Baran B. Kivilcim, Sharlene D. Newman, Fatos T. Yarman Vural

The network properties of the estimated brain networks are studied in order to identify regions of interest, such as hubs and subgroups of densely connected brain regions.

Encoding Multi-Resolution Brain Networks Using Unsupervised Deep Learning

no code implementations13 Aug 2017 Arash Rahnama, Abdullah Alchihabi, Vijay Gupta, Panos Antsaklis, Fatos T. Yarman Vural

We suggest a deep architecture which learns the natural groupings of the connectivity patterns of human brain in multiple time-resolutions.
