PCIC presents a two-level approach to recurring purchase recommendations that combines category-level and item-level models to improve accuracy, recall, and engagement on large-scale sites. The first level operates at the category level to perform broad and efficient candidate filtering, reducing the search space and ensuring that recommendations are consistent with purchasing habits and seasons. The second level applies fine-grained models on items to rank and personalize suggestions using embeddings, collaborative signals, and content attributes, optimizing the individual relevance of each product.
This scalable design makes it possible to handle massive catalogs using techniques such as approximate nearest neighbor search, batch scoring, and real-time inference pipelines. In large-scale test environments, the combination of category plus item showed significant increases in key metrics such as accuracy, recall, and retention rate, as well as improving conversion and engagement by presenting more relevant and timely recommendations.
Practical advantages include lower latency in candidate generation, better coverage of customer preferences with limited historical data, and greater robustness against the emergence of new products. This approach facilitates business strategies such as automatic replenishment, remarketing campaigns, and inventory optimization, positively impacting average order value and purchase recurrence.
