Abstract: A method of extracting features from data defined on geometric domains such as community graphs is disclosed. The method suggests inputting central point data, neighbor point data, and neighbor edge data into an intrinsic local processing layer and applying at least one local operator and at least one operator function, wherein applying the at least one local operator comprises applying at least a local processing function to the data, and applying a local aggregation operation to aggregate the results of the local processing function. The local aggregated operation results are used to determine an output feature. The at least one operator function may be, for example, a Cayley polynomial or a Padé function.
