A new model to extract environmental pattern for fishing ground
Su Fenzhen, Zhou Chenghu, Liu Baoyin, Du Yunyan, Shao Quanqin
2002, (4): 483-493.
Abstract:
The relationship between the forming of fishing ground and the oceanic spatio-temporal field is nonlinear. In order to analyse the relationship between variables with spatio-temporal structures,a spatio-temporal pattern extracting model is provided t...
