Beginner ML Capstone
Take a small tabular problem from question and data audit through model card, test evidence, and deployment recommendation.
Concept overview
What this lesson will help you understand.
A complete small project provides evidence that the learner can connect problem framing, data, modeling, evaluation, communication, and operational judgment.
Learn by doing
Explore the concept.
Make a prediction before changing a control. Run the experiment, explain what moved, and compare the result with the theory below.

Detailed concept deep dive.
Build intuition first, then work through implementation, mathematical derivations, failure analysis, and real system decisions.
7 guided chapters
A complete small project provides evidence that the learner can connect problem framing, data, modeling, evaluation, communication, and operational judgment.
Before working through the formal derivations, connect the vocabulary to one small, concrete example. The goal is not to memorize definitions in isolation. It is to understand what each idea represents, which assumptions make it valid, and how the pieces relate to one another.
Ideas to understand
- Problem statement, user, target, baseline, and error costs
- Data audit, split design, and preprocessing
- Model comparison, evaluation, and model card

Make the idea concrete
Explain the beginner ML capstone with a concrete example and no unexplained jargon.
Try this
- Define “Problem statement, user, target, baseline, and error costs” in your own words, then annotate one concrete Beginner ML Capstone input and output.
- Construct one valid case and one counterexample for “Data audit, split design, and preprocessing”; explain which assumption separates them.
- Predict how “Model comparison, evaluation, and model card” will change one visible playground result, then test and record the before/after values.
Evidence of understanding
- You can explain the example without relying on jargon.
- You can name the assumptions and identify what would invalidate them.
- You can connect the example to at least one real ML use case.
What part of the Beginner ML Capstone mental model still feels least intuitive, and what example would help clarify it?
