Time series forecasting has become a very intensive field of research, which is even increasing in recent years. Deep neural networks have proved to be powerful and are achieving high accuracy in many application fields. For these reasons, they are one of the most widely used methods of machine learning to solve problems dealing with big data nowadays. In this work, the time series forecasting problem is initially formulated along with its mathematical fundamentals. Then, the most common deep learning architectures that are currently being successfully applied to predict time series are described, highlighting their advantages and limitations. Particular attention is given to feed forward networks, recurrent neural networks (including Elman, long-short term memory, gated recurrent units, and bidirectional networks), and convolutional neural networks. Practical aspects, such as the setting of values for hyperparameters and the choice of the most suitable frameworks, for the successful application of deep learning to time series are also provided and discussed. Several fruitful research fields in which the architectures analyzed have obtained a good performance are reviewed. As a result, research gaps have been identified in the literature for several domains of application, thus expecting to inspire new and better forms of knowledge.

Forecasting the future of the stock market is a crucial challenge for companies, financial analysts, policymakers, and other stakeholders. The primary objective is to develop a stable model that can effectively predict stock prices in the face of a volatile financial environment. However, financial time-series forecasting is inherently difficult due to its nonstationary, non-linear, and noisy nature. While various statistical and deep learning models are commonly used for stock price prediction, there is a noticeable lack of research on the effectiveness of different feature pre-processing methods and their combinations for diverse time series. To address this challenge, we propose a hybrid method that incorporates multiple perspectives to achieve optimal results. Our study focuses on financial time-series forecasting in the context of crude oil price fluctuations. The method involves several stages, including feature pre-processing, signal processing, and deep recursive neural networks. Anomalies, representing financial noises, are detected using an unsupervised Autoencoder. Additionally, a data enrichment phase refines the time series using CEEMDAN decomposition and Fourier Transform. Finally, a bi-directional LSTM model is utilized to extract latent patterns and forecast future trends in the time series. This approach aids in the progression of stock market forecasting, imparting valuable perspectives for decision-making among businesses, financial analysts, policymakers, and other individuals with a vested interest.
