“…Various supervised regression algorithms are used in optical communication systems, such as SVR [55,85], IVSTF [32,55,96,98], probabilistic Bayesian learning (PBL) [89] and FS-DBP [55]. Table 3 exhibits supervised ML algorithms for regression in OFDM based optical communication systems in terms of complexity for prediction, advantages, disadvantages, applications, signal type and reachability.…”
