Nearest training digits

    The closest matches from the training set appear here, closest first.

    Loading 750 MNIST training digits… Everything runs in your browser: your drawing is cropped, scaled to 20px and centred by mass on a 28×28 grid, the same way MNIST was prepared, then compared pixel by pixel against every training digit.

    How to play

    Draw a single digit in the pad with a mouse, finger or stylus. The classifier updates as you draw and shows the training digits it matched.

    Change k to see how many neighbours get a vote. Small k trusts the single closest match; large k lets more distant digits outvote it.
