Enhancing Effectiveness and Robustness in a Low-Resource Regime via Decision-Boundary-aware Data Augmentation

no code implementations22 Mar 2024 Kyohoon Jin, Junho Lee, Juhwan Choi, Sangmin Song, Youngbin Kim

Inspired by recent studies on decision boundaries, this paper proposes a decision-boundary-aware data augmentation strategy to enhance robustness using pretrained language models.

User Guide for KOTE: Korean Online Comments Emotions Dataset

1 code implementation11 May 2022 Duyoung Jeon, Junho Lee, Cheongtag Kim

The emotion taxonomy of the 43 emotions is systematically established by cluster analysis of Korean emotion concepts expressed on word embedding space.

Do Not Escape From the Manifold: Discovering the Local Coordinates on the Latent Space of GANs

2 code implementations ICLR 2022 Jaewoong Choi, Junho Lee, Changyeon Yoon, Jung Ho Park, Geonho Hwang, Myungjoo Kang

The global warpage implies that the latent space is not well-aligned globally and therefore the global traversal directions are bound to show limited success on it.

GATSBI: Generative Agent-centric Spatio-temporal Object Interaction

1 code implementation CVPR 2021 Cheol-Hui Min, Jinseok Bae, Junho Lee, Young Min Kim

We present GATSBI, a generative model that can transform a sequence of raw observations into a structured latent representation that fully captures the spatio-temporal context of the agent's actions.

MCW-Net: Single Image Deraining with Multi-level Connections and Wide Regional Non-local Blocks

1 code implementation29 Sep 2020 Yeachan Park, Myeongho Jeon, Junho Lee, Myungjoo Kang

Experimental results on both synthetic and real-world rainy datasets demonstrate that the proposed model significantly outperforms existing state-of-the-art models.

BOOSTING ENCODER-DECODER CNN FOR INVERSE PROBLEMS

no code implementations25 Sep 2019 Eunju Cha, Jaeduck Jang, Junho Lee, Eunha Lee, Jong Chul Ye

However, the computation of the divergence term in SURE is difficult to implement in a neural network framework, and the condition to avoid trivial identity mapping is not well defined.

Boosting CNN beyond Label in Inverse Problems

no code implementations18 Jun 2019 Eunju Cha, Jaeduck Jang, Junho Lee, Eunha Lee, Jong Chul Ye

In this paper, we show that the recent unsupervised learning methods such as Noise2Noise, Stein's unbiased risk estimator (SURE)-based denoiser, and Noise2Void are closely related to each other in their formulation of an unbiased estimator of the prediction error, but each of them are associated with its own limitations.

Polarization Fraction Measurement in same sign WW scattering using Deep Learning

1 code implementation18 Dec 2018 Junho Lee, Nicolas Chanon, Andrew Levin, Jing Li, Meng Lu, Qiang Li, Yajun Mao

Studying the longitudinally polarized fraction of $W^\pm W^\pm$ scattering at the LHC is crucial to examine the unitarization mechanism of the vector boson scattering amplitude through Higgs and possible new physics.
