New research proposes topology preservation for dynamic e-commerce search retrieval

A new research paper explores the challenges of maintaining retrieval quality in dynamic e-commerce search environments where new items are continuously added. The study found that updating the mapping between semantic identifiers (SIDs) and items can significantly degrade retrieval performance, a degradation that can be masked by large beam sizes. The research proposes a topology-preserving principle, which involves fixing old-item SIDs and inserting new ones while warm-starting the model, leading to substantial improvements in retrieval metrics and a measurable increase in online A/B tests.

    Don't Rewrite the SID Map: Topology Preservation for Generative Retrieval in Dynamic E-Commerce Search

    Generative retrieval assigns each item a discrete semantic identifier (SID) and retrieves items by autoregressively generating SID sequences. In dynamic environments such as e-commerce, new items arrive continuously, requiring periodic updates to the SID-to-Item mapping and model…
