NAACL 20212021Frame-based state representation is widely used in modern task-oriented dialog systems to model user intentions and slot values. However, a fixed design of domain ontology makes it difficult to extend to new services and APIs. Recent work proposed to use natural language descriptions to define the domain ontology instead of tag names for each intent or slot, thus offering a dynamic set of schema. In this

MIT Sloan School Sports Analytics Conference 20212021Defensive players in football have complex trajectory patterns that are hard to accurately model and evaluate. This is due to the defenders’ inherently reactive role, which requires them to dynamically respond to offensive strategies and on-the-spot decisions by the quarterback. Amongst defensive players, defensive backs are the most challenging to model. They often travel long distances during passing

CVPR 20212021Reducing inconsistencies in the behavior of different versions of an AI system can be as important in practice as reducing its overall error. In image classification, sample-wise inconsistencies appear as “negative flips”: A new model incorrectly predicts the output for a test sample that was correctly classified by the old (reference) model. Positive congruent (PC) training aims at reducing error rate

NAACL 20212021We propose a practical instant question answering (QA) system on product pages of ecommerce services, where for each user query, relevant community question answer (CQA) pairs are retrieved. User queries and CQA pairs differ significantly in language characteristics making relevance learning difficult. Our proposed transformer-based model learns a robust relevance function by jointly learning unified syntactic

ICASSP 20212021Automatic Speech Recognition (ASR) based on Recurrent Neural Network Transducers (RNN-T) is gaining interest in the speech community. We investigate data selection and preparation choices aiming for improved robustness of RNN-T ASR to speech disfluencies with a focus on partial words. For evaluation we use clean data, data with disfluencies and a separate dataset with speech affected by stuttering. We show
