Neural Network Concept

1.1 What is a
Perceptron?

In machine learning, the Perceptron is an algorithm for supervised learning of binary classifiers. It is the simplest form of a neural network and serves as the building block for more complex architectures.

The Inputs

The perceptron takes several binary inputs ($x_1, x_2, ...$) and produces a single binary output.

The Weights

Weights ($w_1, w_2, ...$) express the importance of the respective inputs to the output.

Knowledge Check

If the sum of weighted inputs is above the threshold, what is the perceptron's output?
