DomainForCoreTrainingProvider Objects

class DomainForCoreTrainingProvider(GraphComponent)

Provides domain without information that is irrelevant for core training.

The information that we retain includes:

  • intents and their "used" and "ignored" entities because intents influence the next action prediction directly and the latter flags determine whether the listed entities influence the next action prediction
  • entities, their roles and groups, and their influence_conversation flag because all of those items are used by policies
  • slots names along with their types, since this type information determines the pre-featurization of slot values
  • response keys (i.e. `utter_*) because those keys may appear in stories
  • form names because those appear in stories
  • how slots are filled (i.e. 'mappings' key under 'slots') because a domain instance needs to be created by core during training time to parse the training data properly

This information that we drop (or replace with default values) includes:

  • the 'session_config' which determines details of a session e.g. whether data is transferred from one session to the next (this is replaced with defaults as it cannot just be removed)
  • the actual text of a 'response' because those are only used by response selectors
  • the actual configuration of 'forms' because those are not actually executed by core components

create

| @classmethod
| create(cls, config: Dict[Text, Any], model_storage: ModelStorage, resource: Resource, execution_context: ExecutionContext) -> DomainForCoreTrainingProvider

Creates component (see parent class for full docstring).

provide

| provide(domain: Domain) -> Domain

Recreates the given domain but drops information that is irrelevant for core.

Arguments:

  • domain - A domain.

Returns:

A similar domain without information that is irrelevant for core training.

create_pruned_version

| @staticmethod
| create_pruned_version(domain: Domain) -> Domain

Recreates the given domain but drops information that is irrelevant for core.

Arguments:

  • domain - A domain.

Returns:

A similar domain without information that is irrelevant for core training.
