  • Publication number: 20230079815
    Abstract: An approach is disclosed that inputs data points to a trained artificial intelligence (AI) model with an outlier model that identifies data points on which the AI model has been trained. A value is received from the outlier model corresponding to each of the data points with the received value being a prediction of whether the AI model has been trained on the respective data point. A bias analysis is performed on the trained AI model using a subset of the data points that received a prediction that indicates that the trained AI model was trained with the respective data point.

  • Patent number: 11580012
    Abstract: Embodiments provide systems, methods, and computer-readable storage media for automated and objective testing of applications or processes. Graphical representations of the application may be analyzed to derive attribute data and identify flows (e.g., possible processing paths that may be accessed during utilization of the application by a user). Test cases may be automatically generated based on the attribute data and the identified flows. Additionally, testing scripts for testing the portions of the application corresponding to each identified flow may be generated using machine learning logic. Once generated, the testing scripts may be executed against the application to test different portions of the application functionality (or processes). Execution of the testing scripts may be monitored to generate feedback used to train the machine learning logic. Reports may be generated based on the monitoring and provided to users to enable the users to resolve any errors encountered during the testing.
