The author liberally alludes to “superposition collapse,” which implies that they’re referring to its quantum mechanical meaning.
It doesn't imply that. What term would you use to refer to the narrowing of a hypothesis space upon acquisition of new evidence?
Bayesian inference?
In a non-Bayesian context, I would call it “updating/retraining my model.”
In a formal Bayesian context, I’d call it “updating my posterior by adding data to the likelihood.”
That could describe both the narrowing or broadening of one's hypothesis space.
Would you say the commonly-used random level generation algorithm in gamedev, Wave Function Collapse, implies it’s using quantum mechanics? Most people would disagree with you, I suspect.
