Methods for automatically configuring performance evaluation schemes for machine learning algorithms
Patent number: 11681931Abstract: A system that provides a mathematical formulation for new problem of model validation and model selection in presence of test data feedback. The system comprises a memory that stores computer-executable components. A processor, operably coupled to the memory, executes the computer-executable components stored in the memory.
