HourglassNeRF: Casting an Hourglass as a Bundle of Rays for Few-shot Neural Rendering

no code implementations16 Mar 2024 Seunghyeon Seo, Yeonjin Chang, Jayeon Yoo, Seungwoo Lee, Hojun Lee, Nojun Kwak

Addressing this, we propose HourglassNeRF, an effective regularization-based approach with a novel hourglass casting strategy.

Tradeoff of generalization error in unsupervised learning

no code implementations10 Mar 2023 Gilhan Kim, Hojun Lee, Junghyo Jo, Yongjoo Baek

In this study, we propose that unsupervised learning generally exhibits a two-component tradeoff of the GE, namely the model error and the data error -- using a more complex model reduces the model error at the cost of the data error, with the data error playing a more significant role for a smaller training dataset.

End-to-End Multi-Object Detection with a Regularized Mixture Model

no code implementations18 May 2022 Jaeyoung Yoo, Hojun Lee, Seunghyeon Seo, Inseop Chung, Nojun Kwak

Recent end-to-end multi-object detectors simplify the inference pipeline by removing hand-crafted processes such as non-maximum suppression (NMS).

Few-Shot Object Detection by Attending to Per-Sample-Prototype

no code implementations16 Sep 2021 Hojun Lee, Myunggi Lee, Nojun Kwak

Second, each support sample is used as a class code to leverage the information by comparing similarities between each support feature and query features.

Training Multi-Object Detector by Estimating Bounding Box Distribution for Input Image

3 code implementations ICCV 2021 Jaeyoung Yoo, Hojun Lee, Inseop Chung, Geonseok Seo, Nojun Kwak

Instead of assigning each ground truth to specific locations of network's output, we train a network by estimating the probability density of bounding boxes in an input image using a mixture model.

Unpriortized Autoencoder For Image Generation

no code implementations12 Feb 2019 Jaeyoung Yoo, Hojun Lee, Nojun Kwak

In this paper, we treat the image generation task using an autoencoder, a representative latent model.
