ICML 20212021In this paper, we investigate a new multi-armed bandit (MAB) online learning model that considers real-world phenomena in many recommender systems: (i) the learning agent cannot pull the arms by itself and thus has to offer payments to users to incentivize arm-pulling indirectly; and (ii) if users with specific arm preferences are well rewarded, they induce a “self-reinforcing” effect in the sense that

ICLR 2021 Workshop on Neural Architecture Search2021Bayesian Optimization (BO) is a successful methodology to tune the hyperparameters of machine learning models. The user defines a metric of interest, such as the validation error, and BO finds the optimal hyperparameters that minimize it. However, the metric improvements on the validation set may not translate to improvements on the test set, especially when tuning models trained on small datasets. While

NAACL 2021 Workshop on Visually Grounded Interaction and Language (ViGIL), ACL Findings 20222021Interactive robots navigating photo-realistic environments need to be trained to effectively leverage and handle the dynamic nature of dialogue in addition to the challenges underlying vision-and-language navigation (VLN). In this paper, we present VISITRON, a multi-modal Transformer-based navigator better suited to the interactive regime inherent to Cooperative Vision-and-Dialog Navigation (CVDN). VISITRON

ACL-IJCNLP 20212021A commonly observed problem with the state-of-the art abstractive summarization models is that the generated summaries can be factually inconsistent with the input documents. The fact that automatic summarization may produce plausible-sounding yet inaccurate summaries is a major concern that limits its wide application. In this paper we present an approach to address factual consistency in summarization

ACL Findings 20212021In Natural Language Understanding (NLU), to facilitate Cross-Lingual Transfer Learning (CLTL), especially CLTL between distant languages, we integrate CLTL with Machine Translation (MT), and thereby propose a novel CLTL model named Translation Aided Language Learner (TALL). TALL is constructed as a standard transformer, where the encoder is a pre-trained multilingual language model. The training of TALL
