MiniLMv2-agentflow-v2-onnx

LLM agent flow text classification

This model identifies common LLM agent events and patterns within the conversation flow. Such events include an apology, where the LLM acknowledges a mistake. The flow labels can serve as foundational elements for sophisticated LLM analytics.

It is ONNX quantized and is a fined-tune of MiniLMv2-L6-H384. The base model can be found here

This model is only for the LLM agent texts in the dialog. For the user texts use this model.

model = ORTModelForSequenceClassification.from_pretrained('minuva/MiniLMv2-agentflow-v2-onnx', provider="CPUExecutionProvider")
tokenizer = AutoTokenizer.from_pretrained('minuva/MiniLMv2-agentflow-v2-onnx', use_fast=True, model_max_length=256, truncation=True, padding='max_length')

pipe = pipeline(task='text-classification', model=model, tokenizer=tokenizer, )
texts = ["My apologies", "Im not sure what you mean"]
pipe(texts)

- 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.
