The Parameters page can be accessed through the side menu.

Create new system parameters to change eva’s behavior. A Parameter is a value that is added to configure software behavior. Insert any value to change how eva behaves.

Types of Parameters

Parameters page for VA using NLP

Parameters page for VA using Zero-Shot model

The NLP confidence score module is not displayed for virtual agents integrated with LLM.

NLP Confidence Score

In a NLP, this is a minimum level of certainty that an intent corresponds to what a user is saying. If the minimum confidence score is below the value set, a Not Expected answer (idk) is delivered.

Adjusting this threshold can impact the precision and recall of the model's predictions. You can set the value by moving the bar or typing a value. Learn more about eva NLP

Request Timeout

Amount of time the virtual agent should wait for a response from OpenAI. You can set a value in seconds to configure your agent's behavior. If the request time exceeds the defined period:

• Gen AI cell: The flow will be halted.

• Knowledge AI: The system will trigger the Not Expected flow.

• Rephrase Answer: The system will deliver a static answer.

• Zero-Shot: System delivers fallback measures depending on where the user is in the conversation. See them here.

The Zero-Shot module is only visible in agents integrated with OpenAI models

Tokens Limit

Zero-Shot models are highly influenced by the limitation of tokens: When the configured limit is reached, the system disables the functions of importing and/or creating new intents.
