Machine learning tools that work where JavaScript works

These calculators are interactive examples of @kanaries/ml, a scikit-learn-style machine learning library for JavaScript and TypeScript. Unlike a form that sends your dataset to a calculation server, each tool parses data, fits models, evaluates metrics, and draws its visualization in the current browser tab.

Start with the confusion matrix calculator when you already have model predictions. Use the logistic regression calculator when you have labeled rows and want to fit an interpretable binary classifier. Each page includes a practical guide, metric explanations, downloadable results, and code that maps the browser calculation to @kanaries/ml documentation and familiar scikit-learn calls.
