k nearest neighbor pattern match queries over spatio-temporal label trajectories

open access: yesTongxin xuebao, 2018
Spatio-temporal label trajectories extended traditional spatio-temporal trajectories with semantic labels.k nearest neighbor pattern match was proposed to return the k nearest trajectories that fulfilled the temporal pattern condition.The Label R-Tree ...

LK-Index: A Learned Index for KNN Queries

open access: yesIEEE Access
The k-Nearest Neighbor (kNN) search is a crucial problem in database and data mining, especially in high-dimensional space. However, traditional kNN algorithms based on distance metrics and brute-force search often have low search efficiency and accuracy,
