case class GreedyEmbeddingHelper[S](embeddingFn: (ops.Output) ⇒ ops.Output, beginTokens: ops.Output, endToken: ops.Output, name: String = "RNNDecoderGreedyEmbeddingHelper") extends Helper[ops.Output, S] with Product with Serializable

RNN decoder helper to be used while performing inference. It uses the argmax over the RNN output logits and passes the result through an embedding layer to get the next input.

embeddingFn

Function that takes an INT32 vector of IDs and returns the corresponding embedded values that will be passed to the decoder input.

beginTokens

INT32 vector with length equal to the batch size, which contains the begin-of-sequence token IDs.

endToken

INT32 scalar containing the end-of-sequence token ID (i.e., token ID which marks the end of decoding).
