A Lazy Approach for Efficient Index Learning
Guanli Liu, Lars Kulik, Xingjun Ma +1
Learned indices using neural networks have been shown to outperform traditional indices such as B-trees in both query time and memory. However, learning the distribution of a large…
A Differentially Private Algorithm for Range Queries on Trajectories
Soheila Ghane, Lars Kulik, Kotagiri Ramamohanarao
We propose a novel algorithm to ensure -differential privacy for answering range queries on trajectory data. In order to guarantee privacy, differential privacy mechanisms add n…
GeoPrune: Efficiently Finding Shareable Vehicles Based on Geometric Properties
Yixin Xu, Jianzhong Qi, Renata Borovica-Gajic +1
On-demand ride-sharing is rapidly growing.Matching trip requests to vehicles efficiently is critical for the service quality of ride-sharing. To match trip requests with vehicles,…
Privacy Preserving Moving KNN Queries
Tanzima Hashem, Lars Kulik, Rui Zhang
We present a novel approach that protects trajectory privacy of users who access location-based services through a moving k nearest neighbor (MkNN) query. An MkNN query continuousl…
