Evaluation plots. The kinds of charts of monitored performance and risk metrics that are plotted to evaluate an AI model. Reliable deployment of an algorithm requires identifying appropriate metrics for performance and risk as well as rigorous, ongoing evaluation. Image created by Isabel Sassoon using Adobe Firefly to show a technical report process flow of statistical model performance and a huge numbers chart.
