COMMA: Propagating Complementary Multi-Level Aggregation Network for Polyp Segmentation

no code implementations Applied Sciences 2022 WooSeok Shin, Min Seok Lee, Sung Won Han

In contrast to existing methods, we focus on propagating complementary information such that the complementary low-level explicit boundary with abstracted high-level representations diminishes the discrepancy.

Multi-View Attention Transfer for Efficient Speech Enhancement

no code implementations22 Aug 2022 WooSeok Shin, Hyun Joon Park, Jin Sob Kim, Byung Hoon Lee, Sung Won Han

In this study, we propose multi-view attention transfer (MV-AT), a feature-based distillation, to obtain efficient speech enhancement models in the time domain.

GaIA: Graphical Information Gain based Attention Network for Weakly Supervised Point Cloud Semantic Segmentation

no code implementations2 Oct 2022 Min Seok Lee, Seok Woo Yang, Sung Won Han

Different from the existing studies, this study aims to reduce the epistemic uncertainty measured by the entropy for a precise semantic segmentation.

TriAAN-VC: Triple Adaptive Attention Normalization for Any-to-Any Voice Conversion

1 code implementation16 Mar 2023 Hyun Joon Park, Seok Woo Yang, Jin Sob Kim, WooSeok Shin, Sung Won Han

The existing methods do not simultaneously satisfy the above two aspects of VC, and their conversion outputs suffer from a trade-off problem between maintaining source contents and target characteristics.

MetricGAN-OKD: Multi-Metric Optimization of MetricGAN via Online Knowledge Distillation for Speech Enhancement

1 code implementation ICML 2023 WooSeok Shin, Byung Hoon Lee, Jin Sob Kim, Hyun Joon Park, Sung Won Han

In speech enhancement, MetricGAN-based approaches reduce the discrepancy between the $L_p$ loss and evaluation metrics by utilizing a non-differentiable evaluation metric as the objective function.
