Has Area Under the ROC Curve (AUC-ROC) become Data Science & AI/ML community’s P-Value?

Just returned from day 1 of Intelligent Health AI conference - and while there were some great speakers & talks - one thing stood out. Of the multiple talks reporting machine learning model performance, all except one talk reported AUC-ROC as the only metric - even for unbalanced datasets. It appears that the AUC-ROC metric is being misused similar to how the P-value has been misused & misinterpreted.

There is more to model evaluation than a single number. In addition to AUC-ROC, we have the Precision-Recall (PR) curve, Sensitivity (Recall), Specificity, F1-score, Positive/Negative Predictive Values, Matthews Correlation Coefficient, Calibration, and many other metrics. The graphic below presents a good summary of the various model performance / evaluation metrics (see articles & book for more details):

Awesome victory for #DeepLearning 👏🏻

GE Healthcare wins FDA clearance for #algorithms to spot type of collapsed lung!

Here’s how the AI algorithm works
————————————————
1. A patient image scanned on a device is automatically searched for pneumothorax.
2. If pneumothorax is suspected, an alert with the original chest X-ray, is sent to the radiologist to review.
3. That technologist would also receive an on-device notification to highlight prioritized cases.
4. Algorithms would then analyze and flag protocol and field of view errors and auto rotate images on device.
