(α, k)-anonymity: an enhanced k-anonymity model for privacy preserving data publishing
TL;DR: It is proved that the optimal (α, k)-anonymity problem is NP-hard, and a local-recoding algorithm is proposed which is more scalable and result in less data distortion.
Proceedings Article
Minimality attack in privacy preserving data publishing
TL;DR: Li et al. as mentioned in this paper introduce a model called m-confidentiality which deals with minimality attacks, and propose a feasible solution to prevent such attacks with very little overhead and information loss.

Proceedings ArticleDOI
Handling Information Loss of Graph Neural Networks for Session-based Recommendation
TL;DR: A lossless encoding scheme and an edge-order preserving aggregation layer based on GRU that is dedicatedly designed to process the losslessly encoded graphs are proposed that outperforms the state-of-the-art models on three public datasets.
Journal ArticleDOI
Efficient method for maximizing bichromatic reverse nearest neighbor
TL;DR: This paper studies a related problem called MaxBRNN: find an optimal region that maximizes the size of BRNNs and comes up with an efficient algorithm called MaxOverlap, which is many times faster than the best-known technique.
