NeurIPS 20222022Deep reinforcement learning algorithms often use two networks for value function optimization: an online network, and a target network that tracks the online network with some delay. Using two separate networks enables the agent to hedge against issues that arise when performing bootstrapping. In this paper we endow two popular deep reinforcement learning algorithms, namely DQN and Rainbow, with updates

EMNLP 20222022We introduce question answering with a context in focus, a task that simulates a free interaction with a QA system. The user reads on a screen some information about a topic and they can follow-up with questions that can be either related or not to the topic; and the answer can be found in the document containing the screen content or from other pages. We call such information context. To study the task

EMNLP 20222022The tasks of humor understanding and generation are challenging and subjective even for humans, requiring commonsense and real-world knowledge to master. Puns, in particular, add the challenge of fusing that knowledge with the ability to interpret lexical-semantic ambiguity. In this paper, we present the ExPUNations (ExPUN) dataset, in which we augment an existing dataset of puns with detailed crowdsourced

EMNLP 20222022An important task for designing QA systems is answer sentence selection (AS2): selecting the sentence containing (or constituting) the answer to a question from a set of retrieved relevant documents. In this paper, we propose three novel sentence-level transformer pre-training objectives that incorporate paragraph-level semantics within and across documents, to improve the performance of transformers for

SLT 20222022One of the limitations of large-scale machine learning models is that they are difficult to adjust after deployment without significant re-training costs. In this paper, we focus on NLU and the needs of virtual assistant systems to continually update themselves through time to support new functionality. Specifically, we consider the tasks of intent classification (IC) and slot filling (SF), which are fundamental
