Neural Network Studio
Build, train and watch a brain learn a boundary
What your child can do at the end
Explain why a network with no hidden layer can only draw a straight boundary
The brief
A straight line cannot separate a ring inside a ring, or two spirals twisting around each other. A neural network bends space until it can. In this studio you control everything: which data it sees, which features it is allowed to look at, how many layers and neurons it has, how it activates, how fast it learns, how much it is penalised for large weights, and how the data is split. You watch every weight change in real time, see what each neuron has learned, and read a running explanation of why the loss is falling, stuck, or exploding.
Skills it develops
How it is assessed
3 graded challenges inside the lab, and 8 questions at the end that check the idea rather than the clicks. Every attempt is saved, so a retry after a mistake counts as the learning it is.
