Robustness and repeated trials

Use robustness and repeated trials to make decisions inspectable.

What you should be able to do

Independently: Log every parameter trial and preserve an untouched test set.

Suggested prerequisites

A short guide

Use robustness and repeated trials to make decisions inspectable. Log every parameter trial and preserve an untouched test set. Read the indicated source section, identify its key concepts and conditions, and work through the example. Record inputs, sources, units and assumptions. Keep your method separate from the result, mark unanswered questions, and review the output against the checklist.

An example

Selecting the best of many trials can overstate performance.

Your task

Log every parameter trial and preserve an untouched test set.

Self-check

Try a practice set

Calculations and choices receive immediate checks. Review open responses yourself against the rubric. All examples are educational.

1. There is a 50% chance of +4 and a 50% chance of −2. Expected payoff?
2. How can you reduce future-information leakage?
3. After the robustness and repeated trials task, state one assumption, one supporting fact and one condition that would change your conclusion.
