What must an engineer create to conduct the perfect input test, and why must it be 'perfect'?
Question: In one to three sentences, state what an engineer must create to run the perfect input test and explain why this input needs to be as accurate as possible.
Sample answer: The engineer must create a hand-labeled bounding box that accurately marks the cat's true location in the image. This input must be as close to perfect as possible so that any remaining error observed in the downstream classifier cannot be blamed on a flawed upstream output, allowing the fault to be attributed with confidence.
Key points:
- A hand-labeled bounding box must be created
- It substitutes for the detector's actual output
- Its accuracy rules out the upstream component as a source of error
- This allows confident attribution to the downstream component if errors persist
Rubric: Full credit: mentions the hand-labeled bounding box and explains that its accuracy is needed to rule out the upstream component as the cause of any remaining error. Partial credit: mentions the hand-labeled input without explaining the reason for its accuracy.
