Key Topics to Revise

1

1. Origin and Meaning of Neural Networks

  • Neural networks were first proposed in 1944 by Warren McCullough and Walter Pitts.
  • The first artificial neural network, called Perceptron, was invented in 1958 by psychologist Frank Rosenblatt.
  • Perceptron was intended to model how the human brain processes visual data and learned to recognize objects.

2. Structure of a Biological Neuron and Its Link to ANN

  • A typical neuron has four parts: dendrites, soma, axon, and synapses.
  • Dendrites receive information from other connected neurons.
  • Soma is the cell body that processes information received from dendrites.
3

3. Layers of a Neural Network

  • A neural network has three layers: input layer, hidden layer, and output layer.
  • The input layer acquires data and feeds it to the network.
  • No processing occurs at the input layer.

4. Biological Neural Network and Artificial Neural Network Comparison

  • Biological neural networks process in parallel, are slow, but are superior to ANN.
  • Artificial neural networks also process in parallel, are fast, but are inferior to BNN.
  • Biological neural networks store information in the synapse.
