Nearchon AI Lab · Virtual lab course

Build a neural network from scratch

A hands-on lab in ten short lessons, about 35 minutes. In each one, Nearchon first explains one idea, step by step, then you build that part yourself: the data, the weights, the bias, the sigmoid, the error, training, hidden neurons and backpropagation. Everything you train runs in your browser.

A real neural network trains in your browser: neurons, weights, bias, the sigmoid, the error, gradient descent, backpropagation and the Adam optimiser, retold in simple words.
