Neural Networks Intuition

Neural networks are inspired by the brain, but don't need to be mysterious. Let's build intuition.

What is a Neural Network?

Layers and Neurons

How a Neuron Works

Key Takeaways

• Neural networks are layers of mathematical transformations
• Each neuron computes: weighted sum + bias + activation
• More layers = ability to learn more complex patterns
• The "learning" happens by adjusting weights and biases
• Use for complex patterns that simpler models can't capture
