 We see that Parsey McParseface is state-of-the-art; more importantly, with
 SyntaxNet you can train larger networks with more hidden units and bigger beam
 sizes if you want to push the accuracy even further: [Andor et al. (2016)]

+As described in our [paper](http://arxiv.org/abs/1603.06042), the first
 step in training the model is to *pre-train* using *local* decisions. In this
 phase, we use the gold dependency to guide the parser, and train a softmax layer
 to predict the correct action given these gold dependencies. This can be
