The algorithm research of Traveling Companion is based on the fuzzy clustering analysis. The traveling companion is achieved via determining companion's characteristic index, tourists' information collection, dynamic fuzzy clustering analysis and finding optimal companion. In addition, it is aimed at solving the problems emerged in the tour and providing tourist enterprises with new tips for marketing...
We present a fast alternative for the popular pixel purity index (PPI) algorithm. This multi-dimensional PPI (MDPPI) algorithm is based on iteratively identifying convex hull indices in low-dimensional random projections. The MDPPI algorithm can yield identical results as the PPI algorithm, but several orders of magnitude faster. Furthermore, we show that the PPI algorithm is simply the MDPPI algorithm...
The Octave Fuzzy Logic Toolkit, a free, open-source toolkit for Octave that provides a large subset of the functionality of the MATLAB Fuzzy Logic Toolbox as well as many extensions, has recently been updated to support fuzzy clustering. This paper introduces the fuzzy clustering capabilities of the toolkit and illustrates their use through two examples. Future work will focus on implementing GUI...
Clustering is a process for classifying objects or patterns in such a way that samples of the same group are more similar to one another than samples belonging to different groups. In this paper, we introduce the clustering method called soft clustering and its type Fuzzy C-Means. The clustering algorithms are improved by implementing the two different membership functions. The Fuzzy C-Means algorithm...
