Ultra Fast Warm Start Solution for Graph Recommendations
This addresses the need for scalable and fast updates in recommender systems, though it appears incremental as it adapts an existing low-rank approximation method.
The paper tackled the problem of updating recommendations quickly in graph-based systems to maintain relevance with new data and changing preferences, achieving up to 30 times faster recommendations with quality gains.
In this work, we present a fast and effective Linear approach for updating recommendations in a scalable graph-based recommender system UltraGCN. Solving this task is extremely important to maintain the relevance of the recommendations under the conditions of a large amount of new data and changing user preferences. To address this issue, we adapt the simple yet effective low-rank approximation approach to the graph-based model. Our method delivers instantaneous recommendations that are up to 30 times faster than conventional methods, with gains in recommendation quality, and demonstrates high scalability even on the large catalogue datasets.
