Koo's discovery makes it possible to peek inside the black box and identify some key features that lead to the computer's decision-making process.

Neural nets learn and make decisions independently of their human programmers. Researchers refer to this hidden process as a "black box." It is hard to trust the machine's outputs if we don't know what is happening in the box.

We've developed scientific methods to study black boxes for hundreds of years now, but these methods have primarily been applied to [living beings] up to this point
