Structure-Encoding Auxiliary Tasks for Improved Visual Representation in Vision-and-Language Navigation

no code implementations20 Nov 2022 Chia-Wen Kuo, Chih-Yao Ma, Judy Hoffman, Zsolt Kira

In Vision-and-Language Navigation (VLN), researchers typically take an image encoder pre-trained on ImageNet without fine-tuning on the environments that the agent will be trained or tested on.

CrossMatch: Improving Semi-Supervised Object Detection via Multi-Scale Consistency

no code implementations29 Sep 2021 Zhuoran Yu, Yen-Cheng Liu, Chih-Yao Ma, Zsolt Kira

Inspired by the fact that teacher/student pseudo-labeling approaches result in a weak and sparse gradient signal due to the difficulty of confidence-thresholding, CrossMatch leverages \textit{multi-scale feature extraction} in object detection.

Learning to Generate Grounded Visual Captions without Localization Supervision

2 code implementations1 Jun 2019 Chih-Yao Ma, Yannis Kalantidis, Ghassan AlRegib, Peter Vajda, Marcus Rohrbach, Zsolt Kira

When automatically generating a sentence description for an image or video, it often remains unclear how well the generated caption is grounded, that is whether the model uses the correct image regions to output particular words, or if the model is hallucinating based on priors in the dataset and/or the language model.
