CIKM 20212021Open-domain conversational QA (ODCQA) calls for effective question rewriting (QR), as the questions in a conversation typically lack proper context for the QA model to interpret. In this paper, we compare two types of QR approaches, generative and expansive QR, in end-to-end ODCQA systems with recently released QReCC and OR-QuAC benchmarks. While it is common practice to apply the same QR approach for both

The Journal of Finance and Data Science (JFDS)2021We present a simple and effective methodology for the generation of lexicons (word lists) that may be used in natural language scoring applications. In particular, in the finance industry, word lists have become ubiquitous for sentiment scoring. These have been derived from dictionaries such as the Harvard Inquirer and require manual curation. Here, we present an automated approach to the curation of lexicons

MLSys 2021 Workshop on Neural Networks and Systems2021The recent emergence of demand for running Graph Neural Networks (GNNs) on giant real world graphs requires more scalable system designs. Due to the sparse and irregular connections a graph has, parallel GNN training encounters the problem of load imbalance among workers. In this paper, we show that previous techniques based on graph partitioning is insufficient to address the load imbalance caused by GNN

ASRU 20212021RNN-T has received a lot of attention recently since it achieves state-of-art WER in automatic speech recognition. To run the RNN-T model in real-time on resource-limited edge devices, model compression is often required. However, typical compression methods are still challenging to apply to RNN-T. First, it takes a lot of fine-tuning time and computing resources (e.g., up to several weeks even with multiple

NeurIPS 2021 Workshop on Databases and AI (DBAI)2021While transformers demonstrate impressive performance on many knowledge intensive (KI) tasks, their ability to serve as implicit knowledge bases (KBs) remains limited, as shown on several slot-filling, question-answering (QA), fact verification, and entity-linking tasks. In this paper, we implement an efficient, data-programming technique that enriches training data with KB-derived context and improves
