why perceptron are called neural networks alt text

neurons take inputs from the dendrites (nerve impulses) and then decdes what to ouput

Not perceptron

A | B | A || B | Not (A || B) | 0 | 0 | 0 | 1 | 0 | 1 | 1 | 0 |
1 | 0 | 1 | 0 | 1 | 1 | 1 | 0 |

0 0 1 0 1 0 1 0 1 1 1 0

In this quiz, you'll set the weights (weight1, weight2) and bias bias to the values that calculate the NOT operation on the second input and ignores the first input.

weight1 = 0.0 weight2 = -0.5 bias = 0.0

# Example Perceptron

And Perceptron

weight1 = 0.5
weight2 = 0.5
bias = -0.9

linear_combination = weight1 * test_input[0] + weight2 * test_input[1] + bias
    output = int(linear_combination >= 0)

Or Perceptron

Or perceptron is very similar to an and perceptron. To convert, just increase the wieghts or the bias.

Xor Perceptron

XOr Perceptron

Non Linear Decision Boundary Only true if one input is true and the other is false

XOR can be solved as a combination of AND, OR and NOT perceptron

If the line needs to move closer to the negative region, we need to subtract the slope
