Change defaults epochs Rasa NLU training

How do I set number of epochs and other hyper parameters while training Rasa core and rasa nlu models? I couldn’t find where I can change this.

Thanks

In the config.yml file. For example:

policies:
  - name: "KerasPolicy"
    epochs: 300
  - name: "FallbackPolicy"
    nlu_threshold: 0.3
    core_threshold: 0.3
    fallback_action_name: 'action_default_fallback'

Thanks.
