Pairwise Approach

Pairwise approaches compare items in pairs to learn preferences or rankings, a common strategy in machine learning tasks like recommendation systems and document ranking. Current research focuses on improving the efficiency and effectiveness of pairwise methods, particularly within the context of large language models, exploring alternatives like setwise approaches to reduce computational cost while maintaining accuracy. These advancements are significant because they address limitations in scalability and efficiency, impacting various applications from information retrieval to personalized recommendations.
