Key Topics to Revise

1

1. Core Idea of ANN

  • ANN is an acronym for Artificial Neural Network.
  • An ANN is a computing system inspired by the biological brain.
  • It processes information through interconnected processing units called neurons.
2

2. Biological Neuron and Its Parts

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

3. Structure of an ANN

  • A neural network has input, hidden, and output layers.
  • The input layer receives raw data with no processing.
  • The hidden layer performs feature extraction and complex computation.
4

4. Forward Propagation and Backward Propagation

  • Forward propagation and backward propagation are the two phases of training an ANN.
  • Forward propagation moves data from the input layer to the output layer to generate a prediction.
  • Backward propagation uses the error between the prediction and the actual output.
