Interview question · Adversarial ML & Model Privacy

A team claims their model is now robust to adversarial inputs. How do you evaluate that claim honestly?

Most broken defences were evaluated by their authors. The scored answer pins down the threat model, attacks the defence specifically, runs sanity checks, and reports robust accuracy with the conditions attached.

What if · the follow-ups in this answer

The answer works through 6 follow-ups like an interviewer would

A paper claims a new defence makes image classifiers secure against adversarial examples, and your company is considering adopting it for a document fraud detector.

  1. How do you make the claim precise?
  2. What attacks should the evaluation include?
  3. What should the results report?
  4. What if your document detector faces different attacks from the paper's?
  5. What if the defence holds up?
  6. What would your evaluation conclude with?

Each rung has a nudge, a model answer, the principle that carries over and the weak answer to avoid. Premium opens every answer and ladder.
