What it does

ResNet helps a very deep AI pass information forward without getting lost.

Residual: The info passed through a shortcut • Layers: Decision levels

How it works

  • Build many layers.
  • Add shortcut paths around some layers.
  • Use the shortcuts so useful information can keep moving.

Uses & Applications

  • A camera app can recognize objects in photos.
  • A quality-check system can spot defects in products.
  • A medical image tool can help sort scans for human review.
In short

Shortcuts help very deep networks learn better.

Try it yourself

Give a signal a shortcut

A number travels through several steps. A shortcut can carry its original value straight to the end.

Your turn

Change one setting at a time. Reset example puts everything back.

Follow a residual connection
