In the era of Big Data, the ability to rapidly retrieve information based on similarity is a cornerstone of modern computing. From recommendation systems to facial recognition, the Nearest Neighbor (NN) search is a fundamental operation. However, as the dimensionality of feature vectors increases—often exceeding thousands of dimensions—the performance of traditional tree-based structures (e.g., KD-trees) degrades to the level of a brute-force linear scan.
To address this, the focus has shifted to Approximate Nearest Neighbor (ANN) search, which trades a small degree of accuracy for substantial gains in speed. While current state-of-the-art algorithms, such as Hierarchical Navigable Small World (HNSW) graphs and IVF-ADC, provide robust solutions, they often struggle with index build time and memory footprint in hyper-scale environments.
