An Efficient Post-hoc Framework for Reducing Task Discrepancy of Text Encoders for Composed Image Retrieval

1 code implementation13 Jun 2024 Jaeseok Byun, Seokhyeon Jeong, Wonjae Kim, Sanghyuk Chun, Taesup Moon

However, we highlight an inherent limitation in these projection-based CIR: a task discrepancy of text encoders between the original pre-training task of the encoders (text $\leftrightarrow$ image) and the target CIR task (image + text $\leftrightarrow$ image), which potentially negatively impacts CIR performance.

MAFA: Managing False Negatives for Vision-Language Pre-training

1 code implementation CVPR 2024 Jaeseok Byun, Dohoon Kim, Taesup Moon

We consider a critical issue of false negatives in Vision-Language Pre-training (VLP), a challenge that arises from the inherent many-to-many correspondence of image-text pairs in large-scale web-crawled datasets.

GRIT-VLP: Grouped Mini-batch Sampling for Efficient Vision and Language Pre-training

1 code implementation8 Aug 2022 Jaeseok Byun, Taebaek Hwang, Jianlong Fu, Taesup Moon

In contrast to the mainstream VLP methods, we highlight that two routinely applied steps during pre-training have crucial impact on the performance of the pre-trained model: in-batch hard negative sampling for image-text matching (ITM) and assigning the large masking probability for the masked language modeling (MLM).

FBI-Denoiser: Fast Blind Image Denoiser for Poisson-Gaussian Noise

1 code implementation CVPR 2021 Jaeseok Byun, Sungmin Cha, Taesup Moon

To that end, we propose Fast Blind Image Denoiser (FBI-Denoiser) for Poisson-Gaussian noise, which consists of two neural network models; 1) PGE-Net that estimates Poisson-Gaussian noise parameters 2000 times faster than the conventional methods and 2) FBI-Net that realizes a much more efficient BSN for pixelwise affine denoiser in terms of the number of parameters and inference speed.
