Simple taxonomy of ML

Descriptive:

  • specify x; learn z(x) or p(z|x) where z is “simpler” than x
  • “what happened?”
  • less value but easy
  • hindsight

Predictive:

  • specify x and y; learn to predict y from x
  • “what will happen?”
  • insight

Prescriptive:

  • specify x, y, and e; learn to prescribe e given x to maximize y
  • “how can we make it happen?”
  • high value but hard
  • foresight
