Analysing real world data streams with spatio-temporal correlations: Entropy vs. Pearson correlation

Temporal and Spatio - Temporal Aggregations over Data Streams usingMultiple Time

Analysing spatio-temporal autocorrelation with LISTA-Viz

Many interesting analysis problems (for example, disease surveillance) would become more tractable if their spatio-temporal structure was better understood. Specifically, it would be helpful to be able to identify autocorrelation in space and time simultaneously. Some of the most commonly used measures of spatial association are LISA statistics, such as the Local Moran’s I or the Getis-Ord Gi*,...

Real-time Monitoring of High-Dimensional Functional Data Streams via Spatio-Temporal Smooth Sparse Decomposition

High dimensional data monitoring and diagnosis has recently attracted increasing attention among researchers as well as practitioners. However, existing process monitoring methods fail to fully utilize the information of high dimensional data streams due to their complex characteristics including the large dimensionality, spatio-temporal correlation structure, and non-stationarity. In this pape...

Continuous Query Processing on Spatio-Temporal Data Streams

This thesis addresses important challenges in the areas of streaming and spatio-temporal databases. It focuses on continuous querying of spatio-temporal environments characterized by (1) a large number of moving and stationary objects and queries; (2) need for near real-time results; (3) limited memory and cpu resources; and (4) different accuracy requirements. The first part of the thesis stud...
