Foundations of Machine Learning for IR

Abstract: Passage retrieval, question answering, and language generation – those are some of the tasks developed for MS MARCO, one of the very few leaderboard-based benchmarks that have a heavy focus on IR tasks. The large-scale nature of the data naturally leads to machine learning (ML) based solutions. In this lecture, we will take a closer look at some of the best performing ML approaches which are based on learning to rank and neural IR, the latter often heavily inspired by the most recent advances in NLP. We will conclude with a critical discussion of the recent neural net wave and its applicability to a wide(r) range of IR tasks.
