  • Publication number: 20250118099
    Abstract: A method includes obtaining an engineering schematic containing multiple symbols and connections involving the symbols, where different ones of the symbols in the engineering schematic represent different types of equipment. The method also includes identifying visual features of the engineering schematic. The method further includes processing the visual features using at least one trained machine learning model to (i) identify boundaries around the symbols in the engineering schematic and (ii) classify the symbols in the engineering schematic into multiple classifications, where different ones of the classifications are associated with different types of symbols.

  • Publication number: 20230297901
    Abstract: A method includes obtaining information associated with multiple collocation events. Each collocation event is associated with an occurrence where multiple entities were collocated with one another. The information associated with each collocation event identifies the entities associated with the collocation event, a duration of the collocation event, one or more locations associated with the collocation event, and a time associated with the collocation event. The method also includes identifying strengths of different relationships involving different ones of the entities based on the information. The strengths are determined using one or more features of the collocation events.

  • Publication number: 20230297879
    Abstract: A method includes obtaining training data having at least one training engineering schematic containing multiple known symbols, where different ones of the known symbols represent different types of equipment. The method also includes augmenting the training data with at least one additional training engineering schematic having at least one synthetic schematic, where the at least one synthetic schematic contains additional known symbols. The method further includes training at least one machine learning model using the training data including the at least one training engineering schematic and the at least one additional training engineering schematic.
