Case Study

Diagnosing error analysis limitations in a novel ML application

Case context: Your ML team is building a system to predict the complex folding structures of newly discovered proteins, a task that no human expert can perform accurately or consistently.

Question: Based on the nature of this task, what limitations should your team expect regarding error analysis, and why will some standard procedures not apply?

Sample answer: Because the team is working on predicting protein structures—a task humans cannot do well—they should expect that many standard error analysis processes will not apply. Specifically, they will lack a human-level performance benchmark to compare their final output or intermediate components against. This means they will not have the powerful error analysis tools that are typically available for human-solvable problems, making it harder to efficiently prioritize the team's work.

Key points:

  • The task involves something humans cannot do well.
  • The system lacks a human-level performance benchmark.
  • Many standard error analysis procedures will not apply without this benchmark.
  • The team will miss out on powerful error analysis tools, reducing their ability to efficiently prioritize work.

Rubric: The response must recognize that the task is not human-solvable, identify the lack of a human-level performance benchmark, and explain that without this benchmark, standard error analysis procedures and efficient team prioritization will be hindered.
