Multi Layer Perceptron
[Neural Network](https://texonom.com/neural-network-86f54f9f1de848c1a29c56c24f7d5094) 


## MLP
Can have non-linear decision boundary
using 3 Perceptron, now available to separate XOR

### Two layer
convex open or closed region

each line means perceptron 



### Three layer
arbitrary (complexity limited by number of neurons)




### Hidden layer
except final layer
