Joaquin Delgado \u6c0f(Amazon Music, Head of Applied Science Search)<\/h3>\n
\u3010\u6982\u8981\u3011In this presentation I will describe the integration with Bist – a Multi-Arm Bandit (MAB) service, to solve the learning-to-rank (LTR) problem in Music Search Entity Resolution (ER) for song voice requests in Amazon Music. Our contributions are three-fold: (i) we highlight the practical advantages of using contextual MABs for LTR in a real deployed system, such as increase in experimental velocity and time-to-market, compared to previous solutions, (ii) we highlight the improvements we make in the customer experience of Amazon Music listeners by surfacing the right song(s) for a voice request, and (iii) we highlight some experiments and challenges we faced in developing a winning model using a hosted service which practitioners should be aware of if they decide to use a MAB service for their own LTR problems.<\/p>\n
