Discovering Data Structures: Nearest Neighbor Search and Beyond
Researchers have developed a novel framework for end-to-end learning of data structures, capable of adapting to data distributions and offering control over complexity. This approach has been successfully applied to nearest neighbor search, where it discovered algorithms akin to binary search and interpolation search in one dimension, and structures resembling k-d trees or locality-sensitive hashing in higher dimensions. The framework can also learn effective data representations and has been adapted for frequency estimation in data streams, showing potential as a discovery tool for new problems. AI
