ICASSP 20222022In this work, we aim to enhance the system robustness of end-to-end automatic speech recognition (ASR) against adversarially-noisy speech examples. We focus on a rigorous and empirical “closed model adversarial robustness” setting (e.g., on-device or cloud applications). The adversarial noise is only generated by closed-model optimization (e.g., evolutionary and zeroth-order estimation) without accessing

The Web Conference 20222022Automatic extraction of product attributes from their textual descriptions is essential for online shopper experience. One inherent challenge of this task is the emerging nature of e-commerce products — we see new types of products with their unique set of new attributes constantly. Most prior works on this matter mine new values for a set of known attributes but cannot handle new attributes that arose

ICASSP 20222022Automatic speech recognition (ASR) is increasingly being used in specialized domains such as medical ASR and news transcription. Owing to the lack of high quality annotated speech data in such domains, off-the-shelf models are commonly employed by fine-tuning on domain-specific data. This poses a significant challenge in transcribing long-tail expressions and out-of-vocabulary (OOV) named entities. On the

AAAI 2022 DE-FACTIFY Workshop: Multi-Modal Fake News and Hate-Speech Detection2022Over the years, memes became very popular as social media services growing rapidly. Understanding meme images as humans do is very complicated because of its multi-modal nature (texts on images). In this paper, we describe our approach for classifying sentiment and emotion of memes for Memotion 2.0 challenge. Assuming correlation between three sub-tasks, we implemented and compared four different multi-task

ICASSP 20222022Audio-visual data allows us to leverage different modalities for downstream tasks. The idea being individual streams can complement each other in the given task, thereby resulting in a model with improved performance. In this work, we present our experimental results on action recognition and video summarization tasks. The proposed modeling approach builds upon the recent advances in contrastive loss based
