maximum-a-posteriori

A point estimate of parameters $\theta$ over dataset $D$, corresponding to the maximum of a posterior distribution $p(\theta \vert D)$:

$\theta_\mathrm{MAP} = \mathrm{arg} \mathrm{max} p(\theta \vert D)$

i.e. the value(s) of $\theta$ that with maximum probability, also referred to as the mode.
