Transition Rate Scheduling for Quantization-Aware Training

no code implementations30 Apr 2024 Junghyup Lee, Dohyung Kim, Jeimin Jeon, Bumsub Ham

It is thus difficult to control the degree of changes for quantized weights by scheduling the LR manually.

AZ-NAS: Assembling Zero-Cost Proxies for Network Architecture Search

no code implementations28 Mar 2024 Junghyup Lee, Bumsub Ham

To address this issue, we propose AZ-NAS, a novel approach that leverages the ensemble of various zero-cost proxies to enhance the correlation between a predicted ranking of networks and the ground truth substantially in terms of the performance.

RankMixup: Ranking-Based Mixup Training for Network Calibration

no code implementations ICCV 2023 Jongyoun Noh, Hyekang Park, Junghyup Lee, Bumsub Ham

In this paper, we present RankMixup, a novel mixup-based framework alleviating the problem of the mixture of labels for network calibration.

OIMNet++: Prototypical Normalization and Localization-aware Learning for Person Search

1 code implementation21 Jul 2022 SangHoon Lee, Youngmin Oh, Donghyeon Baek, Junghyup Lee, Bumsub Ham

To this end, we introduce a novel normalization layer, dubbed ProtoNorm, that calibrates features from pedestrian proposals, while considering a long-tail distribution of person IDs, enabling L2 normalized person representations to be discriminative.

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.

Learning by Aligning: Visible-Infrared Person Re-identification using Cross-Modal Correspondences

1 code implementation ICCV 2021 Hyunjong Park, SangHoon Lee, Junghyup Lee, Bumsub Ham

We address the problem of visible-infrared person re-identification (VI-reID), that is, retrieving a set of person images, captured by visible or infrared cameras, in a cross-modal setting.

Distance-aware Quantization

no code implementations ICCV 2021 Dohyung Kim, Junghyup Lee, Bumsub Ham

This alleviates the gradient mismatch, but causes a quantizer gap problem.

Network Quantization with Element-wise Gradient Scaling

1 code implementation CVPR 2021 Junghyup Lee, Dohyung Kim, Bumsub Ham

Network quantization aims at reducing bit-widths of weights and/or activations, particularly important for implementing deep neural networks with limited hardware resources.

Learning Semantic Correspondence Exploiting an Object-level Prior

no code implementations29 Nov 2019 Junghyup Lee, Dohyung Kim, Wonkyung Lee, Jean Ponce, Bumsub Ham

We address the problem of semantic correspondence, that is, establishing a dense flow field between images depicting different instances of the same object or scene category.

SFNet: Learning Object-aware Semantic Correspondence

no code implementations CVPR 2019 Junghyup Lee, Dohyung Kim, Jean Ponce, Bumsub Ham

We address the problem of semantic correspondence, that is, establishing a dense flow field between images depicting different instances of the same object or scene category.
