intent_classifier_configuration#

class besser.bot.nlp.intent_classifier.intent_classifier_configuration.IntentClassifierConfiguration[source]#

Bases: ABC

The Intent Classifier Configuration abstract class.

This configuration is assigned to a state, allowing the customization of its intent classifier.

This class serves as a template to implement intent classifier configurations for the different Intent Classifiers.

class besser.bot.nlp.intent_classifier.intent_classifier_configuration.LLMIntentClassifierConfiguration(llm_name, parameters={}, use_intent_descriptions=True, use_training_sentences=True, use_entity_descriptions=True, use_entity_synonyms=True)[source]#

Bases: IntentClassifierConfiguration

The LLM Intent Classifier Configuration class.

It allows the customization of a LLMIntentClassifier.

Parameters:

  • llm_name (str) – the name of the LLM to be used (must be created in the bot)

  • parameters (dict) – the LLM parameters (this will vary depending on the suite and the LLM)

  • use_intent_descriptions (bool) – whether to include the intent descriptions in the LLM prompt

  • use_training_sentences (bool) – whether to include the intent training sentences in the LLM prompt

  • use_entity_descriptions (bool) – whether to include the entity descriptions in the LLM prompt

  • use_entity_synonyms (bool) – whether to include the entity value’s synonyms in the LLM prompt

Bases: IntentClassifierConfiguration

The Simple Intent Classifier Configuration class.

It allows the customization of a SimpleIntentClassifier.

Parameters:

  • num_words (int) – Max num of words to keep in the index of words

  • num_epochs (int) – Number of epochs to be run during training

  • embedding_dim (int) – Number of embedding dimensions to be used when embedding the words

  • input_max_num_tokens (int) – Max length for the vector representing a sentence

  • discard_oov_sentences (bool) – whether to automatically assign zero probabilities to sentences with all tokens being oov ones or not

  • check_exact_prediction_match (bool) – Whether to check for exact match between the sentence to predict and one of the training sentences or not

  • activation_last_layer (str) – The activation function of the last layer

  • activation_hidden_layers (str) – The activation function of the hidden layers

  • lr (float) – Learning rate for the optimizer
