Artificial Intelligence computer science machine learning

Artificial Neural Network

  • Computer representation of knowledge that attempts to mimic neural networks of the human body
  • A class of mathematical expression that take inputs (data and neural network weights) and the output are the "predictions" or loss function
  • Training a neural net is the process of adjusting weights and threshold values to minimize a loss function

Comparison to the human neural network

  • Input values --> dendrites
  • Weight values --> Signals passed by dendrites
  • Computation and use of threshold value --> neuron producing a strong signal if enough of the weighted input signals are strong
