  • Patent number: 10887182
    Abstract: This disclosure provides a system for pairwise network alignment. In operation, the system receives datasets from two networks, each network having a plurality of nodes. The two networks are embedded based on multi-layer graph convolution to generate network embeddings. An inner product similarity score is generated between the two networks based on an inner product of the network embeddings. Next, a node correspondence is estimated between the two networks using a SoftMax function on the inner product similarity score. Finally, the two networks are aligned on the node correspondence.

  • Patent number: 10838377
    Abstract: Described is a system for estimating long-term causal effects of interventions on various entities. A synthetic control is generated from selected donor series such that parameters involved in the generation of the synthetic control can be tuned automatically, or manually by a user. Post-intervention synthetic control values are generated from the synthetic control, and estimates of long-term causal effects of an intervention onto aggregate units similar to the donor series are determined. A device is controlled based on the determined estimates.

  • Publication number: 20170316421
    Abstract: Described is a system for identifying emerging trends in a consumer product from heterogeneous online data sources. Data extracted from heterogeneous data sources is fused, and consumer product data is identified from the fused data. A baseline distribution for consumer issues related to consumer products is generated from the set of consumer product data. A deviation value from the baseline distribution is determined for a specific consumer product. Indicators for future consumer issues regarding the specific consumer product are identified based on the deviation value. The indicators are reported to a system analyst.
