EMNLP 20212021Many recent successes in sentence representation learning have been achieved by simply fine-tuning on the Natural Language Inference (NLI) datasets with triplet loss or siamese loss. Nevertheless, they share a common weakness: sentences in a contradiction pair are not necessarily from different semantic categories. Therefore, optimizing the semantic entailment and contradiction reasoning objective alone

Computer Speech & Language Special Issue of INLG2021Incorporating external knowledge sources effectively in conversations is a longstanding problem in open-domain dialogue research. The existing literature on open-domain knowledge selection is limited and makes certain brittle assumptions on knowledge sources to simplify the overall task (Dinan et al., 2019), such as the existence of a single relevant knowledge sentence per context. In this work, we evaluate

DCASE 20212021We introduce several novel knowledge distillation techniques for training a single shallow model of three recurrent layers for acoustic event detection (AED). These techniques allow us to train a generic shallow student model without many convolutional layers, ensembling, or custom modules. Gradual incorporation of pseudo-labeled data, using strong and weak pseudo-labels to train our student model, event

Recsys 2021 Workshop on Context-Aware Recommender Systems2021Online video services acquire new content on a daily basis to increase engagement, and improve the user experience. Traditional recommender systems solely rely on watch history, delaying the recommendation of newly added titles to the right customer. However, one can use the metadata information of a cold-start title to bootstrap the personalization. In this work, we propose to adopt a two-tower model,

EMNLP 2021 Workshop on NLP for Conversational AI2021Intelligent personal assistants (IPAs) such as Amazon Alexa, Google Assistant and Apple Siri extend their built-in capabilities by supporting voice apps developed by third-party developers. Sometimes the smart assistant is not able to successfully respond to user voice commands (aka utterances). There are many reasons including automatic speech recognition (ASR) error, natural language understanding (NLU
