Top claims

  • ▪The GitHub repository includes training scripts, evaluation routines, and model configurations to reproduce benchmark results on MNIST and Fashion-MNIST datasets
  • ▪Raw fingerprint images from the study are withheld from public availability because they contain potentially identifiable biometric information
  • ▪The loop-diffractive neural network model was used to design an optimized diffractive metasurface for the fingerprint identification system
