Explore the Bias-Variance Trade-off on a Tabular Healthcare Cohort
Overview
What this challenge is about.
Train learning curves on a 90,000-patient healthcare dataset, decompose test error into bias and variance, and earn your verifiable certificate.
The Brief
What you'll do, and what you'll demonstrate.
Use learning and validation curves to empirically characterize the bias-variance trade-off across three model families on a real healthcare cohort.
Earning criteria — what you'll demonstrate
- Generate and interpret learning curves and validation curves
- Decompose test error into bias, variance, and irreducible noise empirically
- Connect the bias-variance trade-off to concrete next-step model choices
- Defend modelling choices in writing for a clinically literate audience
