Feedback Alignment: Turns out, if you send error signals backward through completely random, fixed wires (instead of symmetrical weights like backprop requires), the forward-facing neurons will organically adjust themselves to “align” with that random feedback [9]. The brain doesn’t need perfect math; it just needs a directional nudge.
Like the N-closest algorithm, the weight of each candidate is given by the inverse of its distance to the input colour. Because of this, both algorithms produce output of a similar quality, although the N-convex method is measurably faster. As with the last algorithm, more details can be found in the original paper[2].
