  • Patent number: 11636487
    Abstract: In an embodiment, a process for graph decomposition includes initializing nodes and edges of a data graph for analysis using a computer, and performing message passing between at least a portion of the nodes of the data graph to determine a corresponding measure of interest for each node of at least a portion of the data graph. The process further includes receiving an identification of one or more nodes of interest in the data graph, performing message passing between at least a portion of the nodes of the data graph using at least the determined measures of interest to identify a corresponding subgraph of interest for each of the one or more nodes of interest in the data graph, and performing an analysis action using the one or more identified subgraphs of interest.

  • Publication number: 20230111818
    Abstract: In various embodiments, a process for assessing transactional graphs based on generator-discriminator networks includes using a generator network to generate a first set of transaction graph samples that are of a generated type, wherein the generator network is trained to optimize a predetermined objective function. The process includes sampling, from a collected dataset, a second set of transaction graph samples that are of a non-generated type; and providing the first set of transaction graph samples and the second set of transaction graph samples to a discriminator network, wherein the discriminator network is trained to classify a provided transaction graph sample as the generated type or the non-generated type. The process includes discriminating, by the discriminator network, each of at least a portion of the first set of transaction graph samples and the second set of transaction graph samples as the generated type or the non-generated type.

  • Publication number: 20220198471
    Abstract: A graph of nodes and edges is received. An identification of a starting node in the graph is received. Traversal walks on the graph from the starting node are automatically performed, wherein performing each of the traversal walks includes traversing to a randomly selected next node until any of one or more stopping criteria is met. One or more processors are used to determine one or more metrics based on the traversal walks. At least a portion of the one or more metrics is used to predict an illicit activity or entity.

  • Publication number: 20210124780
    Abstract: In an embodiment, a process for graph search and visualization includes receiving a query graph, and calculating one or more vectors for the query graph, where the one or more vectors each identifies a corresponding portion of the query graph. The process includes identifying one or more graphs similar to the query graph including by comparing the calculated one or more vectors for the query graph with one or more previously-calculated vectors for a different set of graphs and outputting the identified one or more similar graphs. The comparison with the previously-calculated vector(s) may be based on previously-calculated vector(s) processed by grouping the one or more vectors into at least one group of vectors, identifying a representative graph for each of the at least one group of vectors; and storing the at least one group of vectors and a respective identified representative graph.

  • Publication number: 20080319812
    Abstract: A software application providing system and methods for using Web Services to connect an Analysis calculator, a Recommendations engine, Social Networking, and Knowledge Management technologies in a platform for operationalizing sustainability into Product Life Cycle Management (e.g., conception, design, manufacture, service, end-of-life disposition) and Enterprise Resource Planning (ERP) (including enterprise-wide activities of manufacturing, supply change management, financials, human resources, customer relationship management, and external stakeholder engagement). A Web Service Framework integrates Life Cycle Assessment (LCA) software technology with product design, manufacturing, and distribution process design tools. A logic layer can perform sustainability estimates within a Knowledge Management System. A Web Service Framework is utilized for constructing or entering LCA models, methodologies and source data.
