INGREX: An Interactive Explanation Framework for Graph Neural Networks

no code implementations3 Nov 2022 Tien-Cuong Bui, Van-Duc Le, Wen-Syan Li, Sang Kyun Cha

Graph Neural Networks (GNNs) are widely used in many modern applications, necessitating explanations for their decisions.

Toward Multiple Specialty Learners for Explaining GNNs via Online Knowledge Distillation

no code implementations20 Oct 2022 Tien-Cuong Bui, Van-Duc Le, Wen-Syan Li, Sang Kyun Cha

Therefore, we propose a novel GNN explanation framework named SCALE, which is general and fast for explaining predictions.

An Attention-Based Speaker Naming Method for Online Adaptation in Non-Fixed Scenarios

no code implementations2 Dec 2019 Jungwoo Pyo, Joohyun Lee, Youngjune Park, Tien-Cuong Bui, Sang Kyun Cha

Also, we applied existing speaker naming models and the attention-based model to real video to prove that our approach shows comparable accuracy to the existing state-of-the-art models and even higher accuracy in some cases.
