Conversation flow text classification

This a ONNX quantized model and is fined-tuned version of nreimers/MiniLMv2-L6-H384-distilled-from-RoBERTa-Large. The original model can be found here

This model identifies common events and patterns within the conversation flow. Such events include an apology, where the agent acknowledges a mistake, and a complaint, when a user expresses dissatisfaction.

This model should be used only for agent dialogs.

Usage

Installation

pip install tokenizers
pip install onnxruntime
git clone https://huggingface.co/minuva/MiniLMv2-agentflow-v2-onnx

Categories Explanation

- OTHER: Responses or actions by the agent that do not fit into the predefined categories or are outside the scope of the specific interactions listed.

- agent_apology_error_mistake: When the agent acknowledges an error or mistake in the information provided or in the handling of the request.

- agent_apology_unsatisfactory: The agent expresses an apology for providing an unsatisfactory response or for any dissatisfaction experienced by the user.

- agent_didnt_understand: Indicates that the agent did not understand the user's request or question.

- agent_limited_capabilities: The agent communicates its limitations in addressing certain requests or providing certain types of information.

- agent_refuses_answer: When the agent explicitly refuses to answer a question or fulfill a request, due to policy restrictions or ethical considerations.

- image_limitations": The agent points out limitations related to handling or interpreting images.

- no_information_doesnt_know": The agent indicates that it has no information available or does not know the answer to the user's question.

- success_and_followup_assistance": The agent successfully provides the requested information or service and offers further assistance or follow-up actions if needed.
