Class label: 0
Python:
Click the canvas to add a point. Use the slider to switch class labels.
If all points have the same class label: creates a Regression dataset; otherwise: Classification.
Why?
Whether I’m answering questions on StackOverflow, teaching someone about classification or regression, or making sure my RANSAC implementation works how I expect it to—I always find myself wanting a tool where I can click to draw some points on a canvas and run my algorithm on it.
