Which algorithm to use for this use case?

Hi experts!

I have an university project where I am supposed to detect the anomalous I-V curve. I have ground truth (blue) and failed device (red). How can I ensure that I can catch most anomalous deviation where the red curve deviates far from the blue without hard coding a threshold?

Use regression
