Turkish Sugar Inc., a public enterprise including 25 factories, is the first corporation of Turkish industry. According to the government policy, public sugar factories PSFs will be privatized as geography-based 6 portfolio groups in two years. As performance measures of PSF affect government, sugar producers, and several unions in privatizing process, a systematic approach is necessary to meas...

The California statewide integrated land use and transportation modeling has being developed using the PECAS framework. This paper focus on two goals: a) presenting a framework for identifying household lifestyle clusters, and b) applying them to a spatial economic model system. A household's lifestyle is defined by two sets of dimensions: space use and household wage. Using a two-step clusteri...

HELIOS2015 is a soccer simulation 2D team which has been participating in the RoboCup competition since 2000. We recently focus on the game analysis from kick records using a clustering method. This paper describes the overview of our approach for clustering game log files using Earth Mover’s Distance.

Often in nature the temporal distribution of inhomogeneous stochastic point processes can be modeled as a realization of renewal Poisson processes with a variable rate. Here we investigate one of the classical examples, namely, the temporal distribution of earthquakes. We show that this process strongly departs from a Poisson statistics for both catalogue and sequence data sets. This indicate t...

This paper discusses the relationships between indiscernibility degree and clustering results in rough clustering. We first examine the relationship between the threshold value of indiscernibility degree and resultant clusters. After that, we apply random disturbance to the perfect relations, and examine how the result changes. The results implies the threshold-validity curve may have globally ...

Crowd analysis and abnormal trajectories detection are the hot topics in computer vision and pattern recognition. As more and more video monitoring equipments are installed in public places for public safety and public management, researches become urgent to learn the crowd behavior patterns through the trajectories obtained by the intelligent video surveillance technology. In this paper, the F...

Data aggregation is a central principle underlying many applications in computer science, from artificial intelligence to data security and privacy. Microaggregation is a special clustering problem where the goal is to cluster a set of points into groups of at least k points in such a way that groups are as homogeneous as possible. A usual homogeneity criterion is the minimization of the within...

A validated simulation model primarily requires performing an appropriate input analysis mainly by determining the behavior of real-world processes using probability distributions. In many practical cases, probability distributions of the random inputs vary over time in such a way that the functional forms of the distributions and/or their parameters depend on time. This paper answers the quest...
