ACL Findings 20222022Users interacting with voice assistants today need to phrase their requests in a very specific manner to elicit an appropriate response. This limits the user experience, and is partly due to the lack of reasoning capabilities of dialogue platforms and the hand-crafted rules that require extensive labor. One possible way to improve user experience and relieve the manual efforts of designers is to build an

ACL 20222022BERT based ranking models have achieved superior performance on various information retrieval tasks. However, the large number of parameters and complex self-attention operations come at a significant latency overhead. To remedy this, recent works propose late-interaction architectures, which allow precomputation of intermediate document representations, thus reducing latency. Nonetheless, having solved

WSDM 20222022Voice assistants such as Alexa, Siri, and Google Assistant have become increasingly popular worldwide. However, linguistic variations, variability of speech patterns, ambient acoustic conditions, and other such factors are often correlated with the assistants misinterpreting the user’s query. In order to provide better customer experience, retrieval based query reformulation (QR) systems are widely used

The Web Conference 20222022Human labeling is time-consuming and costly. This problem is further exacerbated in extremely imbalanced class label scenarios, such as detecting fraudsters in online websites. Active learning selects the most relevant example for human labelers to improve the model performance at a lower cost. However, existing methods for active learning for graph data often assumes that both data and label distributions

ICASSP 20222022Standard acoustic event classification (AEC) solutions require large-scale collection of customer data from client devices for model optimization. However, they inevitably suffer from the risks of compromising customer privacy. Federated learning (FL) is a compelling framework that decouples data collection and model training to protect customer privacy. In this work, we investigate the feasibility of applying
