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?
