Reverse $k$ Nearest Neighbor Search over Trajectories [PDF]

open access: yesIEEE Transactions on Knowledge and Data Engineering, 2018
GPS enables mobile devices to continuously provide new opportunities to improve our daily lives. For example, the data collected in applications created by Uber or Public Transport Authorities can be used to plan transportation routes, estimate capacities, and proactively identify low coverage areas.

k Nearest Neighbor Search for Location-Dependent Sensor Data in MANETs

open access: yesIEEE Access, 2015
K nearest neighbor (kNN) queries, which retrieve the k nearest sensor data items associated with a location (location-dependent sensor data) from the location of the query issuer, are useful for location-based services in mobile environments.

Navigating K-Nearest Neighbor Graphs to Solve Nearest Neighbor Searches [PDF]

open access: yes, 2010
Nearest neighbor queries can be satisfied, in principle, with a greedy algorithm under a proximity graph. Each object in the database is represented by a node, and proximal nodes in this graph will share an edge. To find the nearest neighbor the idea is quite simple, we start in a random node and get iteratively closer to the nearest neighbor following

Pyramid Product Quantization for Approximate Nearest Neighbor Search

open access: yesApplied Sciences
Product quantization (PQ) is a widely adopted technique for efficient approximate nearest neighbor (ANN) search in high-dimensional spaces, offering a favorable balance between accuracy and memory efficiency. However, standard PQ suffers from high online

Engineering optimization by constrained differential evolution with nearest neighbor comparison

open access: yesVietnam Journal of Mechanics, 2016
It has been proposed to utilize nearest neighbor  comparison to reduce the number of function evaluations in unconstrained  optimization. The nearest neighbor comparison omits the function evaluation  of a point when the comparison can be judged by its ...
