Learning from Models and Data for Visual Grounding

no code implementations20 Mar 2024 Ruozhen He, Paola Cascante-Bonilla, Ziyan Yang, Alexander C. Berg, Vicente Ordonez

We introduce SynGround, a novel framework that combines data-driven learning and knowledge transfer from various large-scale pretrained models to enhance the visual grounding capabilities of a pretrained vision-and-language model.

Improved Visual Grounding through Self-Consistent Explanations

no code implementations7 Dec 2023 Ruozhen He, Paola Cascante-Bonilla, Ziyan Yang, Alexander C. Berg, Vicente Ordonez

Vision-and-language models trained to match images with text can be combined with visual explanation methods to point to the locations of specific objects in an image.

SCoRD: Subject-Conditional Relation Detection with Text-Augmented Data

1 code implementation24 Aug 2023 Ziyan Yang, Kushal Kafle, Zhe Lin, Scott Cohen, Zhihong Ding, Vicente Ordonez

To solve this problem, we propose an auto-regressive model that given a subject, it predicts its relations, objects, and object locations by casting this output as a sequence of tokens.

Improving Visual Grounding by Encouraging Consistent Gradient-based Explanations

1 code implementation CVPR 2023 Ziyan Yang, Kushal Kafle, Franck Dernoncourt, Vicente Ordonez

We propose a margin-based loss for tuning joint vision-language models so that their gradient-based explanations are consistent with region-level annotations provided by humans for relatively smaller grounding datasets.

Chair Segments: A Compact Benchmark for the Study of Object Segmentation

1 code implementation2 Dec 2020 Leticia Pinto-Alva, Ian K. Torres, Rosangel Garcia, Ziyan Yang, Vicente Ordonez

We aim for ChairSegments to be the equivalent of the CIFAR-10 dataset but for quickly designing and iterating over novel model architectures for segmentation.

Training Deep Neural Networks with Partially Adaptive Momentum

no code implementations25 Sep 2019 Jinghui Chen, Dongruo Zhou, Yiqi Tang, Ziyan Yang, Yuan Cao, Quanquan Gu

Experiments on standard benchmarks show that our proposed algorithm can maintain fast convergence rate as Adam/Amsgrad while generalizing as well as SGD in training deep neural networks.

On the Convergence of Adaptive Gradient Methods for Nonconvex Optimization

no code implementations16 Aug 2018 Dongruo Zhou, Jinghui Chen, Yuan Cao, Yiqi Tang, Ziyan Yang, Quanquan Gu

In this paper, we provide a fine-grained convergence analysis for a general class of adaptive gradient methods including AMSGrad, RMSProp and AdaGrad.

Closing the Generalization Gap of Adaptive Gradient Methods in Training Deep Neural Networks

2 code implementations18 Jun 2018 Jinghui Chen, Dongruo Zhou, Yiqi Tang, Ziyan Yang, Yuan Cao, Quanquan Gu

Experiments on standard benchmarks show that our proposed algorithm can maintain a fast convergence rate as Adam/Amsgrad while generalizing as well as SGD in training deep neural networks.
