In order to solve this problem we proposed an adaptive grid -based clustering method. Our focus is on providing up-to-date arbitrary shaped clusters along with improving the processing time and bounding the amount of the memory u sage. In our method (B+C tree), a structure called "B+...

A grid-based data clustering method is disclosed. A parameter setting step sets a grid parameter and a threshold parameter. A diving step divides a space having a plurality of data points according to
The main advantage of Grid based method is its fast processing time which depends on number of cells in each dimension in quantized space. In this research paper, we present some of the grid based methods such as CLIQUE (CLustering In QUEst) [2], STING (STatistical INformation Grid) [3],...
Abstract Grid-based clustering is particularly appropriate to deal with massive datasets. The principle is to first summarize the dataset with a grid representation, and then to merge grid cells in order to obtain clusters. All previous methods use grids with hyper-rectangular cells. In this paper...
Create a grid-based tracker. Get tracker = trackerGridRFS('SensorConfigurations',config,... 'AssignmentThreshold',5,... 'MinNumCellsPerCluster',4,... 'ClusteringThreshold',3); Define a theaterPlot object and two associated plotters for visualizing the tracking scene. Get tp = theaterPlot...
clustering pattern in representational space, resulting in canonical grid-like receptive fields (see Fig.2b). In the conceptual case, we predict that typical grid cell firing patterns should not be observed because the clusters (i.e., place cells) do not form a hexagon pattern (Fig.2a) in ...

In the clustering phase, adopting the DBSCAN-based method, the segments in the cells are clustered on the basis of the calibrated values of parameters from the mapping procedure. The extensive experiments indicate that although the results of the adaptive parameter calibration are not optimal, in ...
The experimental results show that grey particle swarm optimization based on TOPSIS, compared with objective weighting method and grey PSO algorithms, it can find many Pareto optimal solutions distributed onto the Pareto front and do not increase the complexity of the algorithm....
