Definition: Let there be a generative model $m$ describing measured data $y$ using model parameters $\theta$ and a prior distribution on $\theta$. Then, the marginal probability distribution of $y$ across the parameter space $\Theta$ is called the marginal likelihood:

\[\label{eq:ml} p(y|m) = \int_{\Theta} p(y,\theta|m) \, \mathrm{d}\theta \; .\]
