How a Machine Learns

A model improves by following tiny slopes toward smaller mistakes

A model starts out wrong about everything. Then it gets better, one tiny nudge at a time. Nudged which way, though?

You'll find out

  • How a machine measures its mistakes
  • Why the step size matters so much
  • What training repeats over and over

Why it matters

Every AI you use was trained by this loop. Seeing it once makes the word training much less mysterious.
