چکیده

High dimensional data values are processed and optimized with feature selection process. A feature selection algorithm is constructed with the consideration of efficiency and effectiveness factors. The efficiency concerns the time required to find a subset of features. The effectiveness is related to the quality of the subset of features. 3 dimensional data models are constructed with object, attribute and context information. Cluster quality is decided with domain knowledge and parameter setting requirements. CAT Seeker is a centroid-based actionable 3D subspace clustering framework. CAT Seeker framework is used to find profitable actions. Singular value decomposition, numerical optimization and 3D frequent itemset mining methods are integrated in CAT Seeker model. Singular value decomposition (SVD) is used to calculating and pruning the homogeneous tensor. Augmented Lagrangian Multiplier Method is used to calculating the probabilities of the values. 3D closed pattern mining is used to fetch Centroid-Based Actionable 3D Subspaces (CATS). Optimal centroid estimation scheme is used to improve the financial data analysis process.. Intra cluster accuracy factor is used to fetch centroid values. Inter cluster distance is also considered in centroid estimation process. Dimensionality analysis is applied to improve the subspace selection process.

Efficient Selectivity Estimation by Histogram Construction Based on Subspace Clustering

Modern databases have to cope with multi-dimensional queries. For efficient processing of these queries, query optimization relies on multi-dimensional selectivity estimation techniques. These techniques in turn typically rely on histograms. A core challenge of histogram construction is the detection of regions with a density higher than the ones of their surroundings. In this paper, we show th...
