Kulankhulana kwa fiber
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 system, monga momwe tawonetsera pa Chithunzi 1. Kafukufuku woyeserera amachitika 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 ELM algorithm kumatha kupititsa patsogolo kasinthidwe kadongosolo, kuthetsa kukhudzika kwa liwiro la kompyuta chifukwa chakuchedwa 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 momwe KK ikulandira chiwembu chokhazikitsidwa ndi offline digital Signal processing (DSP).
