\begin{abstract}
Para acompanhar o aumento na demanda por taxas de transmissão mais altas e melhorias na conectividade de internet, as pesquisas estão se concentrando em métodos eficazes para otimizar o uso de redes ópticas. Tais estudos são fundamentais para desenvolver sistemas que possam, de forma autônoma, coletar informações necessárias para ajustar os parâmetros de transmissão. Isso inclui escolher as modulações adequadas para o meio de comunicação, decidir entre uma transmissão em mono portadora ou múltiplas portadoras, e selecionar os algoritmos mais eficientes para regenerar e corrigir os sinais. Essas abordagens permitem que as redes se ajustem automaticamente para maximizar o desempenho e a eficiência sem intervenção humana direta. Neste contexto, esta dissertação investiga como as técnicas de aprendizado de máquina podem ser aplicadas para automatizar a configuração de parâmetros em sistemas de comunicação óptica. Esse estudo visa melhorar a adaptabilidade e eficiência desses sistemas, permitindo que ajustem suas configurações de forma autônoma com base nas informações adquiridas, otimizando assim a transmissão de dados. Focando em receptores ópticos coerentes flexíveis, o estudo visa aprimorar a eficiência e adaptabilidade destes sistemas ao automatizar o processo de classificação do tipo de modulação e predição do valor de \acrshort{osnr}, elementos cruciais para otimização do desempenho e confiabilidade na transmissão de dados ópticos.

\textbf{Palavras-chave:} Classificação Automática de Modulação, Redes Ópticas, \textit{Random Forest}, \textit{Perceptron} Multicamada.

\begin{foreignabstract}
To keep pace with the increasing demand for higher transmission rates and improvements in internet connectivity, research is focusing on effective methods to optimize the use of optical networks. Such studies are crucial for developing systems autonomously gathering the necessary information to adjust transmission parameters. This includes choosing the most suitable modulations for the communication medium, deciding between single-carrier or multi-carrier transmission, and selecting the most efficient algorithms for signal regeneration and error correction. These approaches allow networks to automatically adjust to maximize performance and efficiency without direct human intervention. This dissertation investigates how machine learning techniques can be applied to automate parameter settings in optical communication systems, aiming to improve adaptability and efficiency by enabling autonomous adjustment of settings based on acquired information. Focusing on flexible coherent optical receivers, the study seeks to enhance system efficiency and adaptability by automating the process of modulation classification and OSNR value prediction, key elements for optimizing performance and reliability in optical data transmission. 

\textbf{Keywords:} Automatic Modulation Classification, Optical Networks, Random Forest, Multilayer Perceptron.

\section{Objetivos da Dissertação}
\subsection{Objetivo geral}
O principal objetivo desta dissertação é investigar o desempenho de modelos de aprendizado de máquina no contexto de um sistema de comunicação óptica. Através da aplicação de uma estratégia para a obtenção de informações sobre a modulação utilizada e o valor de \acrshort{osnr}, sem o conhecimento prévio de informações sobre o sinal no lado do receptor óptico, e demonstrar os resultados obtidos.

\subsection{Objetivos específicos}
\begin{itemize}
    \item Definir e parametrizar o \textit{setup} do \textit{framework} para cada modulação planejada, validando e armazenando os resultados obtidos.
    \item Implementar e analisar os resultados dos algoritmos \textit{ensemble} e redes neurais para a classificação do tipo de modulação no contexto de comunicações ópticas do \textit{framework}.
    \item Implementar e analisar os resultados dos algoritmos \textit{ensemble} de classificação, regressão e redes neurais para predição do valor de \acrshort{osnr} no contexto de comunicações ópticas do \textit{framework}.
    \item Obter um comparativo entre os resultados obtidos para diferentes algoritmos de aprendizado de máquina, demonstrando através das métricas selecionadas, aqueles que apresentam o melhor desempenho.
\end{itemize}
