Those are the expert systems that have fallen out of favour over a decade ago, so thanks, but no thanks.

Sources please, and remember to use relevant sources only, i.e. interpretation of medical image analysis like here [1].
Notably activation maps told researchers precisely nothing about what the neural net was actually basing its conclusions on:
> For other predictions, such as SBP and BMI,
the attention masks were non-specific, such as uniform ‘attention’
or highlighting the circular border of the image, suggesting that
the signals for those predictions may be distributed more diffusely
throughout the image.
So much for "fully white boxes" and "direct interpretability"...
