Ah ha! It’s small _but_ significant. Oscillatory neural network requires no computation as it utilizes universal properties of harmonics. Remember that video of the metronomes getting in sync with one another? Yeah, that. Kuramoto model.
What’s awesome about the Kuramoto model is that, inbetween the coupled oscillations, you can have an infinite variety of combinations of smaller oscillations — SO LONG AS they’re in sync at the beats. See: CHINESE REMAINDER THEOREM. “Clock math” can model it but it naturally works as it’s a universal physics thing. Good good. I’m happy they’re working with this.
