Version and Test the Inference Contract

The curriculum

1. Freeze the Prediction Moment — Free preview

   Choose the target, feature availability and time boundaries before fitting a model.

2. Choose a Loss Before a More Complex Model — Free preview

   Compare constant baselines to understand regression losses.

3. Turn Scores into Review Decisions — Sign-in access

   Use confusion counts and a stated cost model to select a threshold without confusing scores with calibrated probabilities.

4. Combine Votes and Discover Groups — Sign-in access

   Contrast supervised voting with unsupervised clustering using small examples whose limitations remain visible.

5. Inspect a Neuron's Learning Step — Free preview

   Check one small gradient numerically before relying on an automatic differentiation framework.

6. Represent Text with Inspectable Vectors — Sign-in access

   Build a small lexical similarity baseline and identify where word overlap stops representing meaning.

7. Version and Test the Inference Contract — Sign-in access

   Package model metadata, feature expectations and rejection behavior before exposing predictions to another component.

8. Deliver the Repair Forecast Decision Pack — Sign-in access

   Integrate the experiments into a reproducible equipment-planning project with clear human-review boundaries.
