derivation of partition function in conditional random fields
$Z(\bf{x}; {\bf \theta})$ is the conditional partition function:
$$Z({\bf x}; {\bf \theta})=\sum_{{\bf y}\in\mathcal{Y}} \exp\left[-E({\bf y}, {\bf x};{\bf \theta})\right]$$
It is simply the proporti …

What's the difference between a Markov Random Field and a Conditional Random Field?
Let's contrast conditional inference under MRFs with modeling using a CRF, settling on definitions along the way, and then address the original question.
MRF
A Markov Random Field (MRF) with respect …
