text: output_mode: Specification for the output of the layer. Defaults to "binary". Values can be "binary" or "count", configuring the layer as follows: "binary": Outputs a single int array per batch, of num_tokens size, containing 1s in all elements where the token mapped to that index exists at least once in the batch item. "count": As "binary", but the int array contains a count of the number of times the token at that index appeared in the batch item.
