Camera-Driven Representation Learning for Unsupervised Domain Adaptive Person Re-identification

no code implementations ICCV 2023 Geon Lee, SangHoon Lee, Dohyung Kim, Younghoon Shin, Yongsang Yoon, Bumsub Ham

To address the camera bias problem, we also introduce a camera-diversity (CD) loss encouraging person images of the same pseudo label, but captured across various cameras, to involve more for discriminative feature learning, providing person representations robust to inter-camera variations.

Newton Raphson Emulation Network for Highly Efficient Computation of Numerous Implied Volatilities

no code implementations28 Oct 2022 Geon Lee, Tae-Kyoung Kim, Hyun-Gyoon Kim, Jeonggyu Huh

In finance, implied volatility is an important indicator that reflects the market situation immediately.

Set2Box: Similarity Preserving Representation Learning of Sets

1 code implementation7 Oct 2022 Geon Lee, Chanyoung Park, Kijung Shin

Through extensive experiments on 8 real-world datasets, we show that, compared to baseline approaches, Set2Box+ is (a) Accurate: achieving up to 40. 8X smaller estimation error while requiring 60% fewer bits to encode sets, (b) Concise: yielding up to 96. 8X more concise representations with similar estimation error, and (c) Versatile: enabling the estimation of four set-similarity measures from a single representation of each set.

Bi-directional Contrastive Learning for Domain Adaptive Semantic Segmentation

no code implementations22 Jul 2022 Geon Lee, Chanho Eom, Wonkyung Lee, Hyekang Park, Bumsub Ham

We present a novel unsupervised domain adaptation method for semantic segmentation that generalizes a model trained with source images and corresponding ground-truth labels to a target domain.

Video-based Person Re-identification with Spatial and Temporal Memory Networks

1 code implementation ICCV 2021 Chanho Eom, Geon Lee, Junghyup Lee, Bumsub Ham

Spatial and temporal distractors in person videos, such as background clutter and partial occlusions over frames, respectively, make this task much more challenging than image-based person reID.
