This work proposes the methodology for automatically modeling and mining inexact spatial patterns. We first choose attributed relational graph (ARG) as the information representation of the data. The pattern is modelled as a compact parametric pattern ARG (PARG). We formulate the problem as a parameter estimation task and present the procedure for estimating the parameters of the PARG model giv...

Advances in sensing and satellite technologies and the growth of Internet have resulted in a vast amount of uncertain spatial data. Extracting interaction patterns from these uncertain data is a challenging task. In this paper, we propose to model the spatial features in a continuous space through the use of influence functions. For each feature type, we build an influence map that captures the...

the venue for interaction a virtual online data super-store. Additionally, the accessibility to data is no longer tied to ownership or control of the acquiring technology, subject to considerable government restriction, or restricted to only those entities that can invest in considerable computer storage. In recent years, several private companies have built the requisite infrastructure to make...

We propose to cluster class-wise covariance matrices in order to identify different groups of covariances contributing to the same condition. Each cluster represents a different brain pattern associated with one class. Further, we present Clustered Common Spatial Patterns, a new algorithm that applies this technique prior to CSP. We show that CCSP can outperform CSP in a binary imagery movement...

In looking at ecological processes, interest in the pattern of occurrences of species, e.g., the pattern of trees in a forest, say junipers and pinions. In spatial epidemiology, we seek to find pattern in disease cases, perhaps different patterns for cases vs. controls. Exple: breast cancer cases; treatment option mastectomy or radiation In syndromic surveillance we seek to identify disease out...

Density is a critical typology in determining sustainable urban built-form patterns. Built-formrefers to the assemblage and arrangement of the building masses in a city reflecting the spatial layout of spaces.The relationship between density and urban character is also based on at certain densities (thresholds). In a widersense, sustainable cities are a matter of density. Recent debates about t...

drought is one of the natural disasters that causes a lot of damages each year. this phenomenon is a result of severe and repeated spatial-temporal anomalies in atmosphere circulation patterns. thus, studying and identifying the synoptic patterns of this phenomenon is inevitably necessary. in this study, first yearly rainfalls in selected stations of the uremia lake basin were temporally standa...
