Confidence-Based Feature Imputation for Graphs with Partially Known Features

1 code implementation26 May 2023 Daeho Um, Jiwoong Park, Seulki Park, Jin Young Choi

To overcome this limitation, we introduce a novel concept of channel-wise confidence in a node feature, which is assigned to each imputed channel feature of a node for reflecting certainty of the imputation.

Influential Rank: A New Perspective of Post-training for Robust Model against Noisy Labels

no code implementations14 Jun 2021 Seulki Park, Hwanjun Song, Daeho Um, Dae Ung Jo, Sangdoo Yun, Jin Young Choi

Deep neural network can easily overfit to even noisy labels due to its high capacity, which degrades the generalization performance of a model.

Class-Attentive Diffusion Network for Semi-Supervised Classification

1 code implementation18 Jun 2020 Jongin Lim, Daeho Um, Hyung Jin Chang, Dae Ung Jo, Jin Young Choi

In contrast to the existing diffusion methods with a transition matrix determined solely by the graph structure, CAD considers both the node features and the graph structure with the design of our class-attentive transition matrix that utilizes a classifier.
