COORDINATE SYSTEM FOR REPRESENTATION OF MULTIDIMENSIONAL DATA

Distributed Regional Weighted Multidimensional Scaling for Network Coordinate System

Network Coordinate System embeds all nodes into a specific metric space and estimate the latency between any node-pair through computing the corresponding metric distance with low-cost. But the metric space is usually uniform while the Internet is heterogeneous since different autonomous systems (AS) always have different routing strategies. To make full use of the clustering characteristic for...

MedVir: An Interactive Representation System of Multidimensional Medical Data Applied to Traumatic Brain Injury's Rehabilitation Prediction

Clinicians could model the brain injury of a patient through his brain activity. However, how this model is defined and how it changes when the patient is recovering are questions yet unanswered. In this paper, the use of MedVir framework is proposed with the aim of answering these questions. Based on complex data mining techniques, this provides not only the differentiation between TBI patient...

Efficient Representation of Multidimensional Data over Hierarchical Domains

We consider the problem of representing multidimensional data where the domain of each dimension is organized hierarchically, and the queries require summary information at a different node in the hierarchy of each dimension. This is the typical case of OLAP databases. A basic approach is to represent each hierarchy as a one-dimensional line and recast the queries as multidimensional range quer...

Disaster Information Sharing System using Pictograms : Representation of Multidimensional Information

This work aims to support the actions of disaster victims, including tourists and persons who do not understand local language, via information sharing when disasters occur. Existing disaster support systems are often targeted at local residents, and understanding the local language is a prerequisite for use. In consideration of this situation, our system converts linguistic information to a no...
