  • Feed-forward
  • Single hidden layer can learn any function
    • Universal approximation theorem
  • Each hidden layer can operate as a different feature extraction layer
  • Lots of weights to learn
  • Back-Propagation is supervised

Universal Approximation Theory

A finite feed-forward MLP with 1 hidden layer can in theory approximate any mathematical function

Weight Matrix

  • Use matrix multiplication for layer output
  • TLU is hard limiter !tlu.png
  • o_1 to o_4 must all be one to overcome -3.5 bias and force output to 1 !mlp-non-linear-decision.png
  • Can generate a non-linear Decision Boundary
