MLE & MAP Estimation

Maximum Likelihood Estimation and Maximum A Posteriori estimation

What is MLE estimate, prior and MAP estimate?

  • MLE (Maximum Likelihood Estimation): Find parameters that maximize $P(D \theta)$
  • Prior: $P(\theta)$ — belief about parameters before seeing data
  • MAP (Maximum A Posteriori): Find parameters that maximize $P(\theta D) \propto P(D \theta) P(\theta)$
