AAAI 2023 Workshop on Knowledge Augmented Methods for NLP2023The abundance of benchmark datasets supports the recent trend of increased attention given to Question Answering (QA) tasks. However, most of them lack a diverse selection of QA types and more challenging questions. In this work, we present StoryQA, a new task and dataset addressing diverse QA problems for both in-context and out-of-context questions. Additionally, we developed QA models based on large

PPoPP 20232023Jointly utilizing multiple GPUs to train graph neural networks (GNNs) is crucial for handling large graphs and achieving high efficiency. However, we find that existing systems suffer from high communication costs and low GPU utilization due to improper data layout and training procedures. Thus, we propose a system dubbed Distributed Sampling and Pipelining (DSP) for multi-GPU GNN training. DSP adopts a

ISIR-eCom 20232023Commercial search engines use different semantic models to augment lexical matches. These models provide candidate items for a user’s query from a target space of millions to billions of items. Models with different inductive biases provide relatively different predictions, making it desirable to launch multiple semantic models in production. However, latency and resource constraints make simultaneously

AERA 2023 Workshop on Multimodal Literacy in OST Programs: Family and Community Ties2023Computer science (CS) is special among STEM subjects: it aims at an industry sector that has the most job growth but has a constant shortage in the workforce; it is a relatively young and burgeoning subject in K-12 education that has a shortage of classroom teachers; and it is one of a very few STEM subjects that large number of students can master by learning it completely out-of-school. To inspire the

ICASSP 20232023Automatic speech recognition (ASR) models with low-footprint are increasingly being deployed on edge devices for conversational agents, which enhances privacy. We study the problem of federated continual incremental learning for recurrent neural network-transducer (RNN-T) ASR models in the privacy-enhancing scheme of learning on-device, without access to ground truth human transcripts or machine transcriptions
