Not All mAPs are Equal and How to Test Model Robustness

The blog post by Mateo Rojas-Carulla explores the intricacies of model selection and robustness testing in computer vision, focusing on how models with similar mean Average Precision (mAP) scores can behave differently in production. It highlights the importance of robustness analysis over aggregate test metrics, using Lakera's MLTest to identify vulnerabilities and differentiate between models that might seem identical based on mAP alone. The post emphasizes that augmentation strategies, while crucial for building robust models, must be carefully tested as they can sometimes degrade performance rather than improve it. By conducting a detailed robustness scoring, developers can ensure that models are better prepared for the challenges of real-world deployment, making MLTest an essential tool in the model development workflow on platforms like Roboflow.
