What can you tell me about neural networks and how they work?
GPT-5

Neural networks are flexible function approximators: they learn to map inputs (like images, text, or sensor data) to outputs (labels, predictions, actions) by adjusting internal parameters to minimize error on examples.

Key ideas

  • Neurons and layers: A neuron computes a weighted sum of its inputs plus a bias, then applies a non-linear activation (e.g., ReLU, sigmoid, tanh)
  • Forward pass (inference): Data flows from input through hidden layers to output
  • Loss function: Measures how wrong the output is (e.g., cross-entropy for classification)
  • Training via backpropagation: Using the chain rule, the network computes gradients...
