CVPR 2022 Workshop on Gaze Estimation and Prediction in the Wild2022The classic object referring task aims at localizing the referred object in the image and requires a reference image and a natural language description as inputs. Given the facts that gaze signal can be easily obtained by a modern human-computer interaction system with a camera and that human tends to look at the object when referring to it, we propose a novel gaze-assisted object referring framework. The

IWSLT 20222022This paper describes Amazon Alexa AI’s submission to the IWSLT 2022 Offline Speech Translation Task. Our system is an end-to-end speech translation model that leverages pre-trained models and cross modality transfer learning. We detail two improvements to the knowledge transfer schema. First, we implemented a new loss function that reduces knowledge gap between audio and text modalities in translation task

NAACL 20222022Abstractive summarization models are typically pre-trained on large amounts of generic texts, then fine-tuned on tens or hundreds of thousands of annotated samples. However, in opinion summarization, large annotated datasets of reviews paired with reference summaries are not available and would be expensive to create. This calls for fine-tuning methods robust to overfitting on small datasets. In addition

ICASSP 20222022Multimodal active speaker detection (ASD) methods assign a speaking/not-speaking label per individual in a video clip. ASD is critical for applications such as natural human-computer interaction, speaker diarization, and video reframing. Recent work has shown the success of transformers in multimodal settings, thus we propose a novel framework that leverages modern transformer and concatenation mechanisms

NAACL 2022, ACL 2022 Workshop on Semiparametric Methods in NLP: Decoupling Logic from Knowledge2022Previous studies on question answering over knowledge graphs have typically operated over a single knowledge graph (KG). This KG is assumed to be known a priori and is leveraged similarly for all users’ queries during inference. However, such an assumption is not applicable to real-world settings, such as healthcare, where one needs to handle queries of new users over unseen KGs during inference. Furthermore
