Shedding Light on Positional Bias: Strategies for Mitigation in Search Ranking - Haystack EU 2023

Explore strategies for mitigating positional bias in search results during this 33-minute conference talk from Haystack EU 2023. Delve into the challenges of ML-based ranking, where popular items are often algorithmically promoted, creating a self-reinforcing cycle of poor search quality. Learn how to address these biases to improve search relevance, with insights on making ranking models less biased and potentially removing biases from training data. Gain valuable knowledge from real-world experiments conducted at a global food delivery service, including test results and lessons learned from encountered pitfalls. Presented by Burak Isikli, a Staff Machine Learning Engineer at Delivery Hero, this talk offers practical approaches to enhance search ranking and personalization in the context of improving overall search relevance.
