KDD 2021 Workshop on Multi-Armed Bandits and Reinforcement Learning (MARBLE)2021The rich body of Bandit literature not only offers a diverse toolbox of algorithms, but also makes it hard for a practitioner to find the right solution to solve the problem at hand. Typical textbooks on Bandits focus on designing and analyzing algorithms, and surveys on applications often present a list of individual applications. While these are valuable resources, there exists a gap in mapping applications

ACL-IJCNLP 20212021This paper studies joint models for selecting correct answer sentences among the top k provided by answer sentence selection (AS2) modules, which are core components of retrieval-based Question Answering (QA) systems. Our work shows that a critical step to effectively exploit an answer set regards modeling the interrelated information between pair of answers. For this purpose, we build a three-way multi-classifier

Interspeech 20212021In this paper we introduce SmallER, a scalable neural entity resolution system capable of running directly on edge devices. SmallER addresses constraints imposed by the on-device setting such as bounded memory consumption for both model and catalog storage, limited compute resources, and related latency challenges introduced by those restrictions. Our model includes distinct modules to learn syntactic and

KDD 20212021We consider the problem of semantic matching in product search: given a customer query, retrieve all semantically related products from a huge catalog of size 100 million, or more. Because of large catalog spaces and real-time latency constraints, semantic matching algorithms not only desire high recall but also need to have low latency. Conventional lexical matching approaches (e.g., OkapiBM25) exploit

Interspeech 20212021Spoken language understanding (SLU) smart assistants such as Amazon Alexa host hundreds of thousands of voice applications (skills) to delight end-users and fulfill their utterance requests. Sometimes utterances fail to be claimed by smart assistants due to system problems such as model incapability or routing errors. The failure may lead to customer frustration, dialog termination and eventually cause
