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.

Online Continual Learning on a Contaminated Data Stream with Blurry Task Boundaries

2 code implementations CVPR 2022 Jihwan Bang, Hyunseo Koh, Seulki Park, Hwanjun Song, Jung-Woo Ha, Jonghyun Choi

A large body of continual learning (CL) methods, however, assumes data streams with clean labels, and online learning scenarios under noisy data streams are yet underexplored.

Hypergraph-Induced Semantic Tuplet Loss for Deep Metric Learning

1 code implementation CVPR 2022 Jongin Lim, Sangdoo Yun, Seulki Park, Jin Young Choi

In this paper, we propose Hypergraph-Induced Semantic Tuplet (HIST) loss for deep metric learning that leverages the multilateral semantic relations of multiple samples to multiple classes via hypergraph modeling.

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.
