ML Guides

Step-by-step machine learning guides with interactive visualizations. Learn fundamental concepts by experimenting directly in your browser.

Gradient Descent Explained

Interactive visualizer with step-by-step animation. Learn SGD, mini-batch, Adam optimizer, learning rate selection, momentum, and convergence criteria.

Overfitting vs Underfitting

Interactive bias-variance tradeoff visualizer. Adjust polynomial degree to see underfitting, good fit, and overfitting in real time with regularization demos.

K-Fold Cross Validation Explained

Interactive K-Fold simulator. Set K from 2-20, visualize fold assignments with color-coded splits, and compare K values on accuracy charts.

Data Augmentation Gallery

Apply rotation, flip, crop, brightness, contrast, blur, noise, and color jitter to images with live preview. Generate PyTorch and TensorFlow code.

The one paid guide

46,000 users and $1,631

Not a tutorial. A 39-page measured account of what forty extensions and thirty-three sites actually earned me, including the 0.12% conversion figure, the 5,252 impressions that produced zero clicks, and thirteen retractions. $9.99 when checkout opens. It is not open yet, so the only thing to do there today is read the free sample and follow the X account where the opening gets announced.

Read the free sample page first

Everything here is free, no signup. I also sell the three pipelines I built and ran on my own sites first, one payment, full source, at ml0x.com/x. That page prints the failed runs next to the ones that passed audit.
