“…An essential step towards this goal is to set the amplifier gain whenever a system change occurs autonomously. This problem was defined in [3] as Adaptive Control of Optical Amplifier Operating Point (ACOP), and some approaches to solve this problem have already been proposed [1,3,16,18].…”

The Adaptive Control of the optical amplifier Operating Point (ACOP) is one of the problems presented in the challenge of Dynamic operation in optical communication networks. The ACOP approaches aim to define the gains of the optical amplifiers dynamically to increase the transmission quality after a cascade of amplifiers. The most recent ACOP approach uses a multi-objective evolutionary optimization algorithm to define the gains of the amplifiers to maximize the Optical Signal to Noise Ratio (OSNR) and minimize OSNR ripple. Despite the promising results regarding Quality of Transmission, relying on an evolutionary algorithm to make decisions in real-time is not desirable because its iterative method usually implies a high execution time. In previous work, we proposed a surrogate model that can obtain solutions as good as the multi-objective evolutionary algorithm but in less time. We considered five Machine Learning (ML) regression techniques, trained with the optimization algorithm solutions. This article extends the previous work by experimenting with different link lengths, analyzing how the solution is impacted given different numbers of amplifiers on the link. Results showed that the regression median error is less than 1 dB for all cases. One regressor can be used to define amplifiers' gains and variable optical attenuators' losses of an entire optical link. It also showed that the most straightforward regressor is 28,000 times faster than the evolutionary optimization approach.

The significance and value of literature itself determine the importance of literary communication, and literary text communication contains the communication of literary value and significance. Communication is the carrier of transmitting literary works and the bridge between literature and audience. At present, the network new media has become the most frequently used media platform for the public, providing an independent space for individual information production, accumulation, sharing and dissemination. In this paper, literature communication is defined as "the communication of literary text", taking the literature communication caused by "Wang Guozhen's death" as the research object, through the analysis of the content of relevant information and the questionnaire survey of the audience, the statistics show that the people who get the information through wechat circle of friends are the most, accounting for 33%, and the influence of network new media on literature communication and the reasons for its influence are analyzed.

“…Tornar um amplificador óptico adaptável é um desafio recente e algumas abordagens foram propostas [4]- [6]. Contudo, estas propostas dependem de uma boa estimativa do funcionamento do amplificador em diversos cenários, pois a escolha do melhor ponto de operação dependerá da previsão de como será a saída do amplificador em cada um dos possíveis pontos de operação disponíveis.…”

“…Contudo, estas propostas dependem de uma boa estimativa do funcionamento do amplificador em diversos cenários, pois a escolha do melhor ponto de operação dependerá da previsão de como será a saída do amplificador em cada um dos possíveis pontos de operação disponíveis. Em [6], por exemplo, é utilizado um algoritmo evolucionário de otimização multiobjetivo para escolher os melhores pontos de operação para amplificadores em cascata, o otimizador necessita avaliar a qualidade do sinal para definir a aptidão das soluções, essa avaliação depende de uma boa estimativa do sinal óptico.…”
