[Haystack 2020] “How to Build your Training Set for a Learning to Rank Project”, Remote
May 21, 2020 @ 4:00 pm - 5:00 pm
Presented by Alessandro Benedetti, Learning to Rank (LTR) is the application of machine learning techniques (typically supervised), in the formulation of ranking models for information retrieval systems.
With LTR becoming more and more popular, organizations struggle with the problem of how to collect and structure relevance signals necessary to train their ranking models.
This talk is a technical guide to explore and master various techniques to generate your training set(s) correctly and efficiently.
Expect to learn how to :
– model and collect the necessary feedback from the users (implicit or explicit)
– calculate for each training sample a relevance label that is meaningful and not ambiguous (Click Through Rate, Sales Rate …)
– transform the raw data collected in an effective training set (in the numerical vector format most of the LTR training libraries expect)
Join us as we explore real-world scenarios and dos and don’ts from the e-commerce industry.
