case class OutputEmbeddingTransform[FV](numOutputs: Int, outputDim: Int, innerTransform: Transform[FV, DenseVector[Double]], coarsenerForInitialization: Option[(Int) ⇒ Int] = None) extends OutputTransform[FV, DenseVector[Double]] with Product with Serializable

Output embedding technique described in section 6 of http://www.eecs.berkeley.edu/~gdurrett/papers/durrett-klein-acl2015.pdf Basically learns a dictionary for the output as well as an affine transformation in order to produce the vector that gets combined with the input in the final bilinear product.
