There is a sense in which reward splintering is the reverse of interpretability.
Interpretability is basically:
- "This algorithm is doing something really complicated; nevertheless, I want a simple model that explains essentially what it is doing. If there is no obvious simple model, I want an explanatory model to be taught to me with the least amount of complexity, distortion, or manipulation."
Reward splintering is:
- "Here is my simple model of what the algorithm should be doing. I want the algorithm to essentially do that, even if its underlying behaviour is really complicated. If it must deviate from this simple model, I want it to deviate in a way that has the least amount of complexity, distortion, or manipulation."
