Kuyankhulana kwa fiber Optical
Irene Estebanez et al. kuchokera ku The Institute of Physics and Complex Systems ku Spain adagwiritsa ntchito makina ophunzirira kwambiri a Learning Machine (ELM) kuti apezenso zomwe adalandira za mawonekedwe a fiber optical transmission, monga momwe tawonetsera pa Chithunzi 1. Kafukufuku woyesera akuchitika mu 100km optical fiber transmission system pogwiritsa ntchito 56GBand. 4-level pulse amplitude modulation (PAM-4) ndi kuzindikira mwachindunji. Ofufuza adayambitsa kuchedwa kwa algorithm (TDRC) ngati njira yofananira, ndipo adatsimikizira kuti kugwiritsa ntchito njira ya ELM kumatha kupititsa patsogolo kasinthidwe ka makina, kuthetsa mphamvu zochepa za liwiro la kompyuta chifukwa cha kuchedwa kwa nthawi, komanso kukhala ndi magwiridwe antchito ofanana ndi omwe amatengera dongosolo la TDRC [1] ]. Chiwembuchi chimathandizira kumasulira kopanda zolakwika pamene chiŵerengero cha optical-to-noise ratio (OSNR) chili chachikulu kuposa 31dB, ndipo chimakhala ndi zolakwika zabwinoko kuposa njira yolandirira ya KK yomwe imayendetsedwa ndi digito Signal processing (DSP).
