SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill prevents you from judging a machine-learning model in isolation by forcing a fair baseline comparison first, so you can tell whether a complex model is truly better than chance or a simpler alternative.

Core Features & Use Cases

  • Baseline ladder: Recommends dummy, linear, and tree-based baselines before complex models such as XGBoost, LightGBM, neural nets, or transformers.
  • Fair evaluation: Requires the same train/test split or cross-validation folds, the same metric, and the same preprocessing pipeline across every model.
  • Decision support: Flags cases where a reported score is not meaningful without baseline context and refuses to certify a complex model as good when the evidence is insufficient.
  • Use case: If you are about to report an XGBoost ROC-AUC, this Skill tells you which baselines to fit first and how to compare them responsibly.

Quick Start

Ask for a baseline ladder for your supervised learning task and have the skill compare dummy, linear, and random forest models on the same data split and metric before you report your final model.

Frequently Asked Questions about building-baseline-models

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I compare my XGBoost model against fair baseline models?▼

To compare XGboost against fair baseline models, fit dummy, linear, and tree-based benchmarks using the same train/test split, preprocessing pipeline, and metric before evaluating complex models.

Why does my machine learning model evaluation need a baseline comparison?▼

A machine learning model evaluation needs a baseline comparison to prevent judging models in isolation, ensuring the complex model demonstrates true lift over chance or simpler alternatives before certification.

What baseline models should I use for binary classification tasks?▼

For binary classification tasks, establish a baseline ladder starting with dummy classifiers, moving to logistic regression, then random forest benchmarks before deploying complex models.

Can I use cross-validation folds to compare baseline and complex models?▼

Yes, you can use cross-validation folds to compare models by applying identical preprocessing, metric alignment, and bootstrap confidence intervals across every baseline and complex model during evaluation.

When should I not certify a complex supervised learning model?▼

You should not certify a complex supervised learning model when reported scores lack baseline context, or when bootstrap confidence intervals show insufficient evidence of lift over the baseline ladder.
