- 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
- In practice not trainable with Back-Propagation
Weight Matrix
- Use matrix multiplication for layer output
- TLU is hard limiter !

must all be one to overcome -3.5 bias and force output to 1 !- Can generate a non-linear Decision Boundary
