GTI: Graph-based Tree Index with Logarithm Updates for Nearest Neighbor Search in High-Dimensional Spaces
Summary: GTI combines a dataset-wide tree with a lightweight level-1 graph, reducing graph construction and enabling logarithmic-time insertions/deletions. It matches state-of-the-art approximate NNS, supports exact search, and delivers ~10× faster updates than tree-based indexes. (summarized by gpt-5.6-luna on Jul 24 2026)
