2 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.

Parameters

  • Weights and biases inside the model
  • Learned from data during training
  • Billions in a large model
  • Updated by gradient descent

Hyperparameters

  • Settings chosen before training
  • e.g. learning rate, batch size, layers
  • Set by you or a tuning search
  • Not updated by gradient descent
Notice the split: parameters are what the model learns, hyperparameters are the knobs you set to control how it learns.
