I’m using Rasa X for improving my chatbot. I’m getting some conversational errors… the intents are correctly recognised, but the response is often wrong. In particular, many times it returns action_default_fallback even if the intent appears in the stories only before a particular action. Like in this example: [image] Where the intent feedback appears only in this story: [image] This is my config file: language: en pipeline: supervised_embeddings policies: - name: MemoizationPolicy - name: KerasPolicy - name: MappingPolicy - name: TwoStageFallbackPolicy nlu_threshold: 0.15 ambiguity_threshold: 0.1 core_threshold: 0.15 fallback_core_action_name: action_default_fallback fallback_nlu_action_name: action_default_fallback deny_suggestion_intent_name: out_of_scope - name: FormPolicy I kept the threshold very low for trying to solve the issue, but it didn’t work I tried to train the model multiple times but didn’t help

Action_default_fallback returned when not required

Please provide the debug log output so we can see the prediction. Also, if your bot is primarily an FAQ bot with single-turn interactions, switch from the MemoizationPolicy to the AugmentedMemoizationPolicy
