Researchers have developed a novel nested approach for learning rankings and selections from choice-based feedback, particularly useful when a company sequentially displays items and collects customer choices. The proposed algorithms, Nested Elimination (NE) for identifying the best item and Nested Partition (NP) for full-ranking identification, are designed to be efficient and provide strong theoretical guarantees. These algorithms aim to identify the most preferred item or the complete ranking with minimal samples and high confidence, with numerical experiments supporting their effectiveness on both synthetic and real-world data.
