Search Solutions 2020 - Tutorial

Search Solutions 2020

Tuesday 24th November, 2020, Online Event

Search Solutions is the BCS Information Retrieval Specialist Group's annual event focused on practitioner issues in the area of search and information retrieval. The tutorials takes place online on Tuesday 24th November 2020 one day before the Search Solutions event.


Reinforcement Learning for Information Retrieval (Full-day Tutorial)

Alexander Kuhnle, Miguel Aroca-Ouellette, John Reid, Dell Zhang (Blue Prism AI Labs)

There is strong interest in leveraging reinforcement learning (RL) for information retrieval (IR) applications including search, recommendation, and advertising. Just in SIGIR-2020, the term “reinforcement learning” is mentioned in 46 different papers. It has also been reported that Internet companies like YouTube and Alibaba have started to gain competitive advantages from their RL-based search and recommendation engines. This full-day tutorial gives IR researchers and practitioners who have little or no experience with RL the opportunity to learn about the fundamentals of modern RL in a practical hands-on setting. Furthermore, some representative applications of RL in IR systems will be introduced and discussed.
