Emotion Reader

Can AI tell if you're happy or sad?

Step 1 of 3

What you'll learn in this level

  • How a network predicts a feeling from mouth, eyes and eyebrows
  • That a decision needs several features together
  • Why such a prediction is always just a guess

Reading Feelings

Computers can learn to read emotions just like you do! They look for specific patterns in faces.

The net looks at the shape of the mouth and the position of the eyebrows. From that it guesses how someone feels.

How AI Reads Faces

  1. Face Detection

    First the computer finds the face in the picture.

  2. Measuring Features

    It measures how far the eyes, nose and mouth are from each other.

  3. Matching Patterns

    The net compares these measurements with patterns. It learned those patterns during training.

  4. Predicting the Feeling

    It names the feeling that fits best.

Let's see if a simple net can spot feelings.

Guess first, then experiment

The net sees a smiling mouth but angry eyebrows. What does it predict?
