Interactive learning
AI Research
AI Research (Lexicon) is an interactive lab for learning how small neural nets behave. Browse a term guide, take a quiz, then train a letter-guessing model on your own text, with explanations for weights, bias, softmax, and backprop.

Why it exists
I wanted a practical way to learn AI terminology — not just definitions, but enough of a working model to see training and generation happen.
How it's built
The Network Lab uses a small fixed architecture: one-hot inputs, hidden layers, softmax output. Training and generation run in the browser. Most of the work went into getting encodings, training stability, and the diagram accurate.
What's interesting
It's a small product you can poke at: inspect the network, train on your own text, and see where the implementation details matter.
