一、最近邻搜索

1. 随机k-d树算法 (The Randomized k-d TreeAlgorithm)

2. 优先搜索k-means树算法 (The Priority Search K-MeansTree Algorithm)

3. 层次聚类树 (The Hierarchical ClusteringTree)

二、近似最近邻搜索

1. Annoy (Approximate Nearest Neighbors Oh Yeah)

2. ScaNN (Scalable Nearest Neighbors)

3. Faiss (Billion-scale similarity search with GPUs)

4. Hnswlib (fast approximate nearest neighbor search)
