Abstract

The field of time series analysis is rapidly developing as a result of the significant expansion of data production and the diversity of its applications in the fields of economics, finance, energy, healthcare, Meteorology, transport and other areas that rely on accurate forecasting to support decision-making. Traditional studies have relied for many years on statistical models, such as autoregressive models, moving averages (ARIMA) and exponential bootstrapping models, but these models face challenges when dealing with data with nonlinear relationships and complex time patterns. In contrast, machine learning techniques have emerged as advanced tools capable of detecting underlying patterns and extracting complex relationships from data, which has contributed to improving prediction accuracy in many applications. This study aims to provide a comprehensive scientific review of machine learning applications in time series analysis and prediction, by reviewing the theoretical foundations of this field, and discussing the most prominent machine learning algorithms used, including decision trees, random forests, supporting vector machines, artificial neural networks, deep learning models such as long-memory neural networks (LSTM), repeating gate modules (GRU), bypass neural networks (CNN), and transformer models (Transformers). The study also deals with data processing methods, feature extraction, performance evaluation metrics, and the most important challenges associated with data instability, missing values, interpretability of models, and high computer requirements. The study also reviews the results of recent research that compared machine learning models with traditional statistical models, showing the advantages of each and the limits of its use according to the nature of the data and forecasting objectives. Recent trends in the development of hybrid models combining statistical methods and machine learning technologies with the aim of improving the accuracy of forecasting and increasing the reliability of results are also discussed. The study concludes by identifying the most prominent research gaps and proposing a number of future directions, such as explainable artificial intelligence, automated machine learning (AutoML), transfer learning, probabilistic forecasting, and foundational models of time series, which contributes to guiding future research and developing more efficient and effective models in time prediction applications.
