In Microsoft Prompt Flow, evaluation plays a crucial role in assessing how well your AI models perform. Let's explore how you can customize evaluation flows and metrics within Prompt Flow:
Understanding Evaluation in Prompt Flow
In Prompt Flow, a flow represents a sequence of nodes that process input and generate output. Evaluation flows are special types of flows designed to assess the performance of a run based on specific criteria and goals.
Key features of evaluation flows
They typically run after the flow being tested, using its outputs. They calculate scores or metrics to measure the performance of the tested flow. Metrics can include accuracy, relevance scores, or any other relevant measures.
Defining Inputs
Evaluation flows need to take in the outputs of the run being tested. Define inputs similarly to standard flows. For example, if you're evaluating a QnA flow, name an input as "answer." If evaluating a classification flow, name an input as "category." Ground truth inputs (e.g., actual labels) may also be needed.
Outputs and Metrics
Evaluation flows produce results that measure the tested flow's performance. Metrics can be calculated using Python or LLM (Large Language Models). Use the log_metric() function to log relevant metrics.
Using Customized Evaluation Flows
Develop your own evaluation flow tailored to your specific tasks and objectives. Customize metrics based on your evaluation goals. Apply this customized evaluation flow to batch runs for large-scale testing.
Prompt Flow also provides built-in evaluation methods. You can submit batch runs and use these methods to evaluate how well your flow performs with large datasets. View evaluation results, compare metrics, and iterate as needed. Remember, evaluation is essential for ensuring your AI models meet desired criteria and goals.
