Gradient Descent Step by Step
Discover how machines learn by walking blindfolded down a mountain of errors. Master step sizes, batching, and momentum to guide algorithms toward optimal answers.
Like Duolingo, but for Gradient Descent Step by Step. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Finding Your Way Downhill and Navigating Real Landscapes. It starts from scratch.

Key ideas in Gradient Descent Step by Step
- Gradient descent starts by measuring how wrong current predictions are
- It uses the size and direction of that mistake to adjust internal settings
- The process repeats continuously in a loop until mistakes shrink
- Altitude represents the amount of prediction error or loss
- Higher elevations mean the model is making large, inaccurate guesses
- The goal is always to move down toward the lowest possible altitude
- The slope tells you the direction of steepest increase in error
- Gradient descent always moves in the exact opposite direction of the uphill slope to reduce error
- A steeper slope means a more dramatic rise, clarifying the right way down
- The cyclical trial-and-error process gradient descent uses to improve predictions
- Gradient descent makes small, gradual adjustments to existing settings
- Incremental adjustments preserve the progress made by earlier steps
- It refines current parameters rather than trying random guesses
- A flat surface means the slope has dropped to zero
- Zero slope indicates no further downhill step can be taken
- Reaching flat ground signals that the algorithm has found the lowest local valley
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Gradient Descent Step by Step the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
