Helpful first
- Basic algebra
- Functions
What it builds
- Represent input pixels as neuron activations.
- Ask which parameters make a network expressive.
- Connect adjustable weights with a pattern-recognition task.
Useful moments
Check yourself: What changes when weights change while the network’s architecture stays the same?
