Interface MlFillMaskInferenceOptions

Name	Type	Description
mask_token	string	The string/token which will be removed from incoming documents and replaced with the inference prediction(s). In a response, this field contains the mask token for the specified model/tokenizer. Each model and tokenizer has a predefined mask token which cannot be changed. Thus, it is recommended not to set this value in requests. However, if this field is present in a request, its value must match the predefined value for that model/tokenizer, otherwise the request will fail.
num_top_classes	integer	Specifies the number of top class predictions to return. Defaults to 0.
results_field	string	The field that is added to incoming documents to contain the inference prediction. Defaults to predicted_value.
tokenization	MlTokenizationConfigContainer	The tokenization options to update when inferring
vocabulary	MlVocabulary
