Hierarchical Aggregation Approach for Distributed clustering of spatial datasets
Malika Bendechache, Nhien-An Le-Khac, M-Tahar Kechadi
In this paper, we present a new approach of distributed clustering for spatial datasets, based on an innovative and efficient aggregation technique. This distributed approach consi…
On a Distributed Approach for Density-based Clustering
Nhien-An Le-Khac, M-Tahar Kechadi
Efficient extraction of useful knowledge from these data is still a challenge, mainly when the data is distributed, heterogeneous and of different quality depending on its correspo…
A Tree-based Approach for Detecting Redundant Business Rules in very Large Financial Datasets
Nhien-An Le-Khac, Sammer Markos, M-Tahar Kechadi
Net Asset Value (NAV) calculation and validation is the principle task of a fund administrator. If the NAV of a fund is calculated incorrectly then there is huge impact on the fund…
Efficient Large Scale Clustering based on Data Partitioning
Malika Bendechache, Nhien-An Le-Khac, M-Tahar Kechadi
Clustering techniques are very attractive for extracting and identifying patterns in datasets. However, their application to very large spatial datasets presents numerous challenge…
Variance-based Clustering Technique for Distributed Data Mining Applications
Lamine M. Aouad, Nhien-An Le-Khac, Tahar Kechadi
Nowadays, huge amounts of data are naturally collected in distributed sites due to different facts and moving these data through the network for extracting useful knowledge is almo…
