Patent Searching and Data


Title:
INCORPORATING SPATIAL KNOWLEDGE FOR CLASSIFICATION
Document Type and Number:
WIPO Patent Application WO2005017815
Kind Code:
A3
Abstract:
We propose using different classifiers based on the spatial location of the object. The intuitive idea behind this approach is that several classifiers may learn local concepts better than a "universal" classifier that covers the whole feature space. The use of local classifiers ensures that the objects of a particular class have a higher degree of resemblance within that particular class. The use of local classifiers also results in memory, storage and performance improvements, especially when the classifier is kernel-based. As used herein, the term "kernel-based classifier" refers to a classifier where a mapping function (i.e., the kernel) has been used to map the original training data to a higher dimensional space where the classification task may be easier.
