Analyzing Pipeline Component Inputs for Human-Level Performance Comparison

Question: When informally debugging a machine learning pipeline by comparing its components to human-level performance, why is it critical that the human evaluator is restricted to the exact inputs of the component being tested (e.g., outputs of prior components) rather than having access to the raw initial data (e.g., camera images)?

Sample answer: It is critical because giving the human evaluator raw initial data (like camera images) instead of the component's actual inputs (like detection outputs) would result in an unfair comparison. If the human evaluates path planning using raw images, they are using information that the path planning component does not have access to. Restricting the human to the same inputs allows us to isolate the performance of the path planning component itself, rather than testing the combined effect of the detector errors and path planning errors.

Key points:

  • Using raw inputs gives the human evaluator access to information not available to the component.
  • Restricting the human to the same inputs ensures a fair, isolated comparison of that specific component.
  • It prevents upstream component errors from confounding the evaluation of the downstream component.

Rubric: Answers should explain that comparing a component to a human who has access to raw data mixes up errors from upstream components with errors of the current component. It must mention that using identical inputs isolates the performance of the specific component being evaluated.
