NAACL 20222022Providing conversation models with background knowledge has been shown to make open-domain dialogues more informative and engaging. Existing models treat knowledge selection as a sentence ranking or classification problem where each sentence is handled individually, ignoring the internal semantic connection among sentences in background document. In this work, we propose to automatically convert the background

NAACL 20222022With the growing popularity of deep-learning models, model understanding becomes more important. Much effort has been devoted to demystify deep neural networks for better interpretability. Some feature attribution methods have shown promising results in computer vision, especially the gradient-based methods where effectively smoothing the gradients with reference data is key to a robust and faithful result

NAACL 20222022Self-learning paradigms in large-scale conversational AI agents tend to leverage user feedback in bridging between what they say and what they mean. However, such learning, particularly in Markov-based query rewriting systems have far from addressed the impact of these models on future training where successive feedback is inevitably contingent on the rewrite itself, especially in a continually updating

Nature Machine Intelligence2022Combinatorial optimization problems are pervasive across science and industry. Modern deep learning tools are poised to solve these problems at unprecedented scales, but a unifying framework that incorporates insights from statistical physics is still outstanding. Here we demonstrate how graph neural networks can be used to solve combinatorial optimization problems. Our approach is broadly applicable to

ICDE 20222022Amazon Athena is a serverless, interactive query service that allows efficiently analyzing large volumes of data stored in Amazon S3 using ANSI SQL. Some design choices in the engine, especially those concerning streaming of intermediate results, can result in suboptimal executions for query patterns that have common expressions. In this paper we build upon recent work and introduce new optimizations in
