A New Way to Describe Spatiotemporal Data

摘要：

　　Data analysis especially draling with spatiotemporal data in a human-centric way becomes essential in modern engineering and science fields.In this study,we present a granular way of data analysis where the data are described by information granules defined in spatial and temporal domain.We show that the data can be effectively described through a collection of Cartesian products of information granules and their convolution.The quality of the codebooks (vocabulary) is evaluated by data granulation-degranulation.Finally a synthetic example is given to illustrate our algorithm.
