An Experimental Review on Deep Learning Architectures for Time Series Forecasting. Deep neural networks have successfully been applied to address time series forecasting problems, which is a very important topic in data mining. In this work, we face two main challenges: a comprehensive review of the latest works using deep learning for time series forecasting; and an experimental study comparing the performance of the most popular architectures. The datasets used comprise more than 50000 time series divided into 12 different forecasting problems. By training more than 6000 models on these data, we provide the most extensive deep learning study for time series forecasting. The complete report of results is provided in the results folder.

With TimeFlex we developed a flexible yet efficient model that processes the trend in the time domain to capture changes over time in the distribution and applies Fourier Transform on the seasonal component to better capture periodic patterns. They present a comparison of SotA models on different time series tasks and data sets and a widely used library for benchmarking purposes.The evaluations often fail to reveal a clear connection between a model’s architectural nuances and specific characteristics of the datasets, which limits the ability to explain why a certain model performs better in specific scenarios. In this article, we generated datasets using Gaussian Processes (GPs) that allow for extensive evaluations of time series forecasting models, considering specific architectural choices and data attributes. Building on these insights, we proposed TimeFlex as a novel time series forecasting architecture that decomposes seasonal and trend components, enhancing the ability to learn periodic patterns by processing the seasonal part in the frequency domain and effectively learning trends over time in the time domain.
In addition to apparent information, hidden patterns and irregular values pose challenges in learning temporal dependencies (Chen et al 2024d Contiformer: Continuous-time transformer for irregular time series modeling. The increasingly complicated TSF problems are presenting researchers with growing challenges, which has recently led to the active development of new methodologies and algorithms to address these issues (Lim and Zohren 2021 Time-series forecasting with deep learning: a survey.

Deep learning has revolutionized time series analysis with architectures like FNNs, LSTMs, CNNs, TCNs, and Transformers. We’ll use a synthetic dataset that mimics real-world time series characteristics, including trend, seasonality, and noise and real world data from ERCOT on electricity load.
