Hi all, I’m trying to handle chitchat messages in my bot. i.e, if the user say let us say “jnndnj”, I want my nlu model to recognize it as a chitchat and to execute a fall back action. To achieve this, my first try has been to use a TwoStageFallback action, that triggered a certain actions by default. Here is my config file.
# - name: MemoizationPolicy
# - name: EmbeddingPolicy
- name: KerasPolicy
- name: FormPolicy
- name: TwoStageFallbackPolicy
nlu_threshold: 0.2
core_threshold: 0.3
fallback_nlu_action_name: action_handle_default_fallback
fallback_core_action_name: action_handle_default_fallback
deny_suggestion_intent_name: "chitchat"
However, anytime, the user types in a chichat kind intent, the bot doesn’t always trigger the action_handle_default_fallback
and I can see in the logs, a ```None intent`` from rasa nlu`.
So my question is how to deal with this Null/None intent ?
Thanks in advance for your responses. Your sincerely.
