LSTNet models

Long- and Short-term Time-series network models, commonly referred to as LSTNet models, are deep learning architectures designed for multivariate time series forecasting that capture both short-term local patterns and long-term temporal dependencies across multiple interacting variables. The framework integrates convolutional neural network layers to extract localized cross-variable correlations with recurrent neural network layers, often enhanced with recurrent-skip connections, to identify long-range periodic trends. To overcome the scale-insensitivity limitations of deep neural networks, LSTNet architectures also incorporate a parallel linear autoregressive component that directly models linear trends and stabilizes predictions when input signal magnitudes fluctuate significantly over time.

Introduces LSTNet, a deep learning architecture that integrates convolutional and recurrent neural networks with an autoregressive model to capture both short-term local dependencies and long-term trends while addressing scale insensitivity in multivariate time series forecasting.

Multivariate time series forecasting is an important machine learning problem across many domains, including predictions of solar plant energy output, electricity consumption, and traffic jam situation. Temporal data arise in these real-world applications often involves a mixture of long-term and short-term patterns, for which traditional approaches such as Autoregressive models and Gaussian Process may fail. In this paper, we proposed a novel deep learning framework, namely Long- and Short-term Time-series network (LSTNet), to address this open challenge. LSTNet uses the Convolution Neural Network (CNN) and the Recurrent Neural Network (RNN) to extract short-term local dependency patterns among variables and to discover long-term patterns for time series trends. Furthermore, we leverage traditional autoregressive model to tackle the scale insensitive problem of the neural network model. In our evaluation on real-world data with complex mixtures of repetitive patterns, LSTNet achieved significant performance improvements over that of several state-of-the-art baseline methods. All the data and experiment codes are available online.
