What is Machine Learning in Time Series Forecasting?

Machine Learning in Time Series Forecasting applies neural networks, random forests, and gradient boosting to predict future values in univariate and multivariate time series data.

This subtopic focuses on ML models that capture nonlinear patterns in temporal data, outperforming traditional statistical methods in high-dimensional settings. Key works include deep neural networks for long- and short-term patterns (Lai et al., 2018, 1913 citations) and comprehensive surveys of deep learning architectures (Lim and Zohren, 2021, 1443 citations). Over 10 listed papers compare ML accuracy against benchmarks in domains like energy and finance.

Key Challenges

Why It Matters

ML forecasting improves energy load predictions, as in Kuster et al. (2017, 482 citations), enabling efficient grid management. In finance, CNN-LSTM models forecast stock prices (Lu et al., 2020, 480 citations), aiding investment decisions. During COVID-19, supervised ML predicted case growth rates (Rustam et al., 2020, 522 citations), supporting supply chain planning (Nikolopoulos et al., 2020, 482 citations). Makridakis et al. (2018, 1290 citations) show ML reduces errors in real-world M competitions.

Key Research Challenges

Handling Long-Term Dependencies

Deep networks struggle with capturing both short- and long-term patterns in multivariate series. Lai et al. (2018) propose dual mechanisms, yet computational demands remain high. Shih et al. (2019, 869 citations) introduce attention to weigh temporal patterns.

Accuracy vs. Interpretability Trade-off

ML models like gradient boosting excel in accuracy but lack explainability compared to ARIMA. Makridakis et al. (2018) find ML superior in accuracy yet caution on interpretability gaps. Botchkarev (2019, 573 citations) analyzes metrics exposing these tensions.

Hyperparameter Tuning Scalability

Tuning in high-dimensional time series is computationally intensive. Lim and Zohren (2021) survey architectures requiring extensive optimization. Kumar and Thenmozhi (2006, 232 citations) highlight SVM vs. random forest tuning challenges in stock forecasting.
