Python-Perceptron

An Basic implementation of the perceptron, the build block a neural net.

Usage

pip install PyPerceptron

Example

Here's how to instanitate the Perceptron

from Perceptron.perceptron import Perceptron

p = Perceptron(number_inputs, learning_rate, Activation_fn, Loss_fn)

from Perceptron.perceptron import Perceptron
from Perceptron.functions.activationFunctions.heaviside import Heaviside
from Perceptron.functions.lossFunctions.quadratic_loss import QuadraticLoss

dataset = [[2.7810836, 2.550537003, 0],
               [1.465489372, 2.362125076, 0],
               [3.396561688, 4.400293529, 0],
               [1.38807019, 1.850220317, 0],
               [3.06407232, 3.005305973, 0],
               [7.627531214, 2.759262235, 1],
               [5.332441248, 2.088626775, 1],
               [6.922596716, 1.77106367, 1],
               [8.675418651, -0.242068655, 1],
               [7.673756466, 3.508563011, 1]]


p = Perceptron(2, 0.1, Heaviside(), QuadraticLoss()) # number of inputs, learning rate, activation function, loss funciton
p.train(dataset, 3, 30)

for d in dataset:
    assert p.evaluate(d[0], d[1]) == d[2]
