Reinforcement Learning for Adversarial Query Generation to Enhance Relevance in Cold-Start Product Search (2025.acl-industry)
Copied to clipboard
| Challenge: | Existing methods do not incorporate feedback from the query relevance model, limiting their ability to generate queries that enhance product retrieval. |
| Approach: | They propose an adversarial reinforcement learning framework that exposes weaknesses in query classification models by creating synthetic queries that augment the classifier's training set. |
| Outcome: | The proposed framework improves query generation performance on public datasets and on proprietary datasets. |
DiAL : Diversity Aware Listwise Ranking for Query Auto-Complete (2024.emnlp-industry)
Copied to clipboard
| Challenge: | Query Auto-Complete (QAC) is an essential search feature that helps users articulate their query by suggesting relevant completions as they type. |
| Approach: | They propose a new framework that explicitly optimizes for diversity alongside customer feedback signals to balance relevance and diversity. |
| Outcome: | The proposed framework yields an improvement of 8.5% in MRR and 22.8% in NDCG compared to the pairwise ranking approach on an eCommerce dataset. |
