Characterizing Large Language Models as Rationalizers of Knowledge-intensive Tasks

ACL 2024findings

Large language models (LLMs) are proficient at generating fluent text with minimal task-specific supervision. However, their ability to generate rationales for knowledge-intensive tasks (KITs) remains under-explored. Generating rationales for KIT solutions, such as commonsense multiple-choice QA, re…

SemARFlow: Injecting Semantics into Unsupervised Optical Flow Estimation for Autonomous Driving

ICCV 2023poster

Unsupervised optical flow estimation is especially hard near occlusions and motion boundaries and in low-texture regions. We show that additional information such as semantics and domain knowledge can help better constrain this problem. We introduce SemARFlow, an unsupervised optical flow network de…

Spatially Constrained Adversarial Attack Detection and Localization in the Representation Space of Optical Flow Networks

IJCAI 2023poster

Optical flow estimation have shown significant improvements with advances in deep neural networks. However, these flow networks have recently been shown to be vulnerable to patch-based adversarial attacks, which poses security risks in real-world applications, such as self-driving cars and robotics.…

Low-resource Interactive Active Labeling for Fine-tuning Language Models

EMNLP 2022finding

Recently, active learning (AL) methods have been used to effectively fine-tune pre-trained language models for various NLP tasks such as sentiment analysis and document classification. However, given the task of fine-tuning language models, understanding the impact of different aspects on AL methods…

Optical Flow Training under Limited Label Budget via Active Learning

ECCV 2022poster

"Supervised training of optical flow predictors generally yields better accuracy than unsupervised training. However, the improved performance comes at an often high annotation cost. Semi-supervised training trades off accuracy against annotation cost. We use a simple yet effective semi-supervised t…
