 generates tokens conditioned on the sequence of tokens previously generated.  In other words, it operates one step at a time: it generates each token conditioned on the sequence of tokens previously generated. Examples of autoregressive models include RNNs, LSTMs, CNNs (masked convolution layers), and Transformers (from [[https://arxiv.org/pdf/1711.02281.pdf|Gu 2017]]).
-**Definition: Non-Autoregressive ([[https://arxiv.org/pdf/1711.02281.pdf|Gu 2017]]):** A non-autoregressive model removes the conditional dependence between output tokens and generates them in parallel.
+**Definition: Non-Autoregressive ([[https://arxiv.org/pdf/1711.02281.pdf|Gu 2017]]):** A non-autoregressive model removes the conditional dependence between output tokens and generates them in parallel.  See equation 3 of [[https://arxiv.org/pdf/1711.02281.pdf|Gu 2017]] for an example.
-Note: There are also **global** models like [[ml:Conditional Random Field|Conditional Random Fields]], which are not autoregressive and not non-autoregressive by the above definitions.  Instead they perform inference (dynamic programming, MCMC, etc) to maximize a global scoring function.
