5 stops · basics first
  1. Machine Learning ✓ understood

    Building systems that learn patterns from data instead of following hand-written rules, getting better at a task as they see more examples.

  2. Neural Network ✓ understood

    A computational model inspired by biological neural networks, consisting of interconnected nodes (neurons) organized in layers that process information through weighted connections.

  3. Activation Function ✓ understood

    A non-linear function applied to neuron outputs that introduces non-linearity, enabling networks to learn complex patterns.

  4. Sigmoid ✓ understood

    An activation function that squashes values to range (0,1), often used for binary classification and gates in LSTMs.

  5. ReLU ✓ understood

    Rectified Linear Unit - an activation function that outputs the input if positive, zero otherwise. f(x) = max(0, x).

  6. Swish · you are here ✓ understood

A smooth activation function (x * sigmoid(x)) that often outperforms ReLU, discovered through neural architecture search.

This concept is essential for understanding neural networks & deep learning and forms a key part of modern AI systems.
