We propose a nonlinear optical approach for ultra-fast, matrix-vector multiplications as required in machine-learning tasks. Optical multiplication is experimentally demonstrated, with less than 0.05% classification accuracy reduction compared to digital results on the MNIST dataset.Authors: Hao Liu, University of Southampton, SO17 1BJ, Southampton, UK / Kostas Sozos, Dept. of Informatics and Computer Engineering, University of West Attica, Aghiou Spiridonos, 12243, Egaleo, Athens, Greece / Stavros Deligiannidis, Dept. of Informatics and Computer Engineering, University of West Attica, Aghiou Spiridonos, 12243, Egaleo, Athens, Greece / Suttikarn Wantee, University of Southampton, SO17 1BJ, Southampton, UK / Charis Mesaritakis, Dept. of Biomedical Engineering, University of West Attica, Aghiou Spiridonos, 12243, Egaleo, Athens, Greece / Kyle Bottrill, University of Southampton, SO17 1BJ, Southampton, UK / Adonis Bogris, Dept. of Informatics and Computer Engineering, University of West Attica, Aghiou Spiridonos, 12243, Egaleo, Athens, Greece / Periklis Petropoulos, University of Southampton, SO17 1BJ, Southampton, UK
