What is a perceptron?

Updated May 17, 2026

Short answer

A perceptron is the simplest neural network unit used for binary classification.

Deep explanation

It computes a weighted sum of inputs, applies an activation function, and outputs binary results. It forms the foundation of deep learning.

Real-world example

Spam detection in emails.

Common mistakes

  • Assuming perceptrons can solve non-linear problems alone.

Follow-up questions

  • What limitation does perceptron have?
  • How is it improved?
