The author compressed the Bad Apple animation into a small MLP with sine activations (SIREN), using only 790k parameters (~3MB) to represent 2.7 billion pixels, with improvements like time-stretching and motion-focused sampling reducing validation MSE by ~9x.
SirenFNO leverages sinusoidal representation networks to learn full-frequency Fourier kernels, eliminating frequency truncation and achieving significant parameter reductions while improving accuracy on PDE benchmarks.
Pebblebee's Halo is a Bluetooth tracker that doubles as a personal safety device with a 130dB siren, strobe light, and automatic emergency alerts. It supports Apple Find My and Google Find Hub networks, offering a practical alternative to pepper spray for personal safety on walks.
