Hi,
I'm aware of numerous Explainable AI (XAI) solutions for CNNs, however they ~all seem to be tailored for classification (or segmentation).
I also see that for a small home-made model (lets say 15 layers) in Keras or pythorch it's not a big deal to have these things like SHAP or LRP work. However i don't know if something easily applicable exists for detection task and complex CNN architectures like an FPN+backbone network+something_more_that_makes_things_complicated?
