A Recursive Mоdel Index (RMI) uses а hierаrchy оf mоdels to аpproximate the mapping from a key to its position in a sorted array. Consider a simple two-level RMI: • A single top-level model that maps a key to a coarse predicted position or to a bucket ID. • Many bottom-level models, each trained on a small partition of keys with nearly linear behavior.You can choose between two model families: • Neural network (NN) • Linear regression (LR)Which combination of models at the top and bottom levels is generally the most sensible choice for balancing accuracy and lookup latency in a learned index?
