Compare Kernel SVMs and Gradient Boosting on Imbalanced Tabular Data
Overview
What this challenge is about.
Compare Kernel SVMs and Gradient Boosting on Imbalanced Tabular Data. Advanced challenge in analysis. Analyzing real datasets and building models that drive ...
The Brief
What you'll do, and what you'll demonstrate.
Decide whether kernel SVMs still belong in the production credit-risk model zoo or whether gradient boosting wins on every axis that matters.
This is not a data exercise. It is the work an analyst does when stakeholders need answers from messy data. That distinction matters to every hiring manager who has seen candidates describe statistical methods and none who have extracted insight from messy, real-world data.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Apply nested cross-validation for honest model selection
- Compare kernel methods against tree-ensemble methods on real tabular data
- Quantify probability calibration with ECE and reliability diagrams
- Defend a model choice across statistical, calibration, and operational axes
