Biological Neuron

@heldtogether

Like Overflowing a Vessel

• Invented in 1957 • Binary Classifier Algorithm • “Activates” if weighted sum

of inputs exceed a threshold

1. Perceptron

@heldtogether

Given inputs ,And expected output :

1. Training a Perceptron

i0 i1

0 0 0

0 1 0

1 0 0

1 1 1

1. Demo: Logical AND

@heldtogether

XOR

OR

AND

2. Neural Network

@heldtogether

2. Sigmoid Neuron

• Accepts any number as input

• Doesn’t have a threshold, output can be any number

@heldtogether

2. Training the Network

To adjust input weight ,Given output error :

i0 i1

0 0 0

0 1 1

1 0 1

1 1 0
