Step 3: Curate an Evaluation Set from stakeholder feedback

Step 3: Curate an Evaluation Set from stakeholder feedback#

Expected time: 10 - 60 minutes

Time varies based on the quality of the responses provided by your stakeholders. If the responses are messy or contain lots of irrelevant queries, you will need to spend more time filtering and cleaning the data.

You can find all of the sample code referenced throughout this section here.

Overview & expected outcome#

This step will bootstrap an evaluation set with the feedback that stakeholders have provided by using the Review App. Note that you can bootstrap an evaluation set with just questions, so even if your stakeholders only chatted with the app vs. providing feedback, you can follow this step.

Visit documentation to understand the Agent Evaluation Evaluation Set schema - these fields are referenced below.

At the end of this step, you will have an Evaluation Set that contains:

  1. Requests with a 👍 :

    • request: As entered by the user

    • expected_response: If the user edited the response, that is used, otherwise, the model’s generated response.

  2. Requests with a 👎 :

    • request: As entered by the user

    • expected_response: If the user edited the response, that is used, otherwise, null.

  3. Requests without any feedback e.g., no 👍 or 👎

    • request: As entered by the user

Across all of the above, if the user 👍 a chunk from the retrieved_context, the doc_uri of that chunk is included in expected_retrieved_context for the question.

Important

Databricks recommends that your Evaluation Set contain at least 30 questions to get started. Read the evaluation set deep dive to learn more about what a “good” evaluation set is.

Requirements#

  • Stakeholders have used your POC and provided feedback

  • All requirements from previous steps

Instructions#

  1. Open the 04_create_evaluation_set Notebook and press Run All.

  2. Inspect the Evaluation Set to understand the data that is included. You need to validate that your Evaluation Set contains a representative and challenging set of questions. Adjust the Evaluation Set as required.

  3. By default, your evaluation set is saved to the Delta Table configured in EVALUATION_SET_FQN in the 00_global_config Notebook.

Next step: Now that you have an evaluation set, use it to evaluate the POC app’s quality/cost/latency.
