FallbackClassifier Objects

class FallbackClassifier(IntentClassifier)

process

| process(message: Message, **kwargs: Any) -> None

Process an incoming message.

This is the components chance to process an incoming message. The component can rely on any context attribute to be present, that gets created by a call to :meth:rasa.nlu.components.Component.create of ANY component and on any context attributes created by a call to :meth:rasa.nlu.components.Component.process of components previous to this one.

Arguments:

  • message - The :class:rasa.shared.nlu.training_data.message.Message to process.

is_fallback_classifier_prediction

is_fallback_classifier_prediction(prediction: Dict[Text, Any]) -> bool

Checks if the intent was predicted by the FallbackClassifier.

Arguments:

  • prediction - The prediction of the NLU model.

Returns:

True if the top classified intent was the fallback intent.

undo_fallback_prediction

undo_fallback_prediction(prediction: Dict[Text, Any]) -> Dict[Text, Any]

Undo the prediction of the fallback intent.

Arguments:

  • prediction - The prediction of the NLU model.

Returns:

The prediction as if the FallbackClassifier wasn't present in the pipeline. If the fallback intent is the only intent, return the prediction as it was provided.
