Abstract

A computer-implemented method for learning structural relationships between nodes of a graph includes the steps: generating a knowledge graph comprising nodes representing a system and applying a graph-based convolutional neural network (GCNN) to the knowledge graph to generate feature vectors describing structural relationships between the nodes. The GCNN comprises: (i) a graph feature compression layer configured to learn subgraphs representing embeddings of the nodes of the knowledge graph into a vector space, (ii) a neighbor nodes aggregation layer configured to derive neighbor node feature vectors for each subgraph and aggregate the neighbor node feature vectors with their corresponding subgraphs to yield aggregated subgraphs, and (iii) a subgraph convolution layer configured to generate the feature vectors based on the aggregated subgraphs. Functional groups of components included in the system may then be identified based on the plurality of feature vectors.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional To the benefit of the application, all of these documents are hereby incorporated by reference in their entirety. technical field [0003] The present invention generally relates to a method, system, and apparatus related to convolutional neural networks (CNNs) involving learning tasks designed for graph invariance at the layer level and sub-layer level. The disclosed methods, systems and apparatus can be applied, for example, to analyze functional data corresponding to a digital twin. Background technique [0004] Machine learning and convolutional neural networks (CNNs) have achieved great success in solving clustering and classification problems such as grid-structured Euclidean data (1D signals such as time series and 2D datasets such as images). However, many other real-world problems require learning on unstructured data. For example, in the field of engineering, many n...
