  • Patent number: 10970183
    Abstract: A system and method intelligently and automatically improves the performance of a model. The system employs heuristics to select a plurality of performance rules that conform to one or more criteria specified for the performance analysis process. The performance rules include checks to be run on the model and offer advice, such as proposed changes that, if made to the model, may improve its performance. The system may evaluate the proposed changes to determine whether or not they produce an improvement in the model's performance. Proposed changes validated as improving model performance are retained, while proposed changes found not to improve performance are removed.

  • Patent number: 9753615
    Abstract: A device may receive information identifying a model including information associated with elements included in the model. The device may cause the model to be executed, and may collect data associated with executing the model. The device may determine performance information based on the collected data. The performance information may be associated with the elements included in the model. The device may generate a heat map based on the performance information. The heat map may associate an element, of the elements, with a visual representation indicating performance information, associated with the element, based on a heat map scale. The heat map scale may relate the performance information, associated with the element, to performance information associated with another element. The heat map may be a graphical interface that includes a graphical representation of the element and a graphical representation of the other element. The device may provide the heat map.
