Training

Stay organized with collections Save and categorize content based on your preferences.

When your agent is trained, Dialogflow uses your training data to build machine learning models specifically for your agent. Each flow of your agent has its own model. This training data primarily consists of intents, intent training phrases, and entities referenced in a flow; which are effectively used as machine learning data labels. However, agent models are built using parameter prompt responses, state handlers, agent settings, and many other pieces of data associated with your agent.

Whenever you change your agent, you should ensure that the agent is trained before attempting to use it. Depending on your agent settings, training may occur automatically or manually.

When training is initiated by the console, the task indicator provides status for the tasks.

Draft flow automatic training

ML settings allow you to select either a Standard NLU or Advanced NLU NLU type. The standard NLU type has a setting to enable or disable automatic training. The advanced NLU type does not support automatic training.

If you have disabled automatic training, or the NLU type does not support automatic training, you must execute manual training after you have completed updates.

Draft flow manual training

To manually train a flow from the console, click the Train NLU button in the ML settings.

To manually train a flow with the API, call the train method for the Flow type.

Select a protocol and version for the Flow reference:

Flow version automatic training

Whenever a new flow version is created, the new flow version is automatically trained.

To create a new flow version from the console, click the Create button on the Version panel.

To create a new flow version with the API, call the create method for the Version type.
