Executive Overview
Our novel PMSRWKV-GCN framework addresses the critical challenges in multivariate time series forecasting by effectively modeling both intra-series temporal and inter-series spatial dependencies. This two-stage approach leverages advanced techniques like Fast Fourier Transform (FFT) for periodic cue extraction, a multi-scale time-mixing module, and a multi-scale Graph Convolutional Network (GCN). The channel-independent (CI) pre-training strategy prevents early interference, leading to cleaner temporal representations, while the GCN adeptly captures complex spatial correlations. This results in significantly improved accuracy and stability across diverse real-world datasets, offering a robust solution for enterprise-level predictive analytics.
Core Methodology
PMSRWKV-GCN employs a two-stage learning process. Initially, the Fast Fourier Transform (FFT) is used to identify dominant periodicities, guiding the design of a multi-scale time-mixing module based on the RWKV model. A channel-independent (CI) pre-training strategy focuses on learning clean, channel-specific temporal representations, preventing cross-channel interference. In the fine-tuning stage, a multi-scale Graph Convolutional Network (GCN) is introduced to capture inter-series spatial dependencies through scale-aware aggregation, dynamically refining adjacency matrices for adaptive modeling.
Key Results
Experimental evaluations across eight real-world datasets demonstrate PMSRWKV-GCN's consistent superior performance over representative baseline models. Notably, it achieves an 11.86% average MSE reduction on the Electricity dataset and up to 39.51% lower MSE with the multi-scale GCN for complex spatial dependencies. Ablation studies confirm that CI pre-training significantly strengthens temporal modeling (1.92%-3.73% MSE reduction), while the multi-scale GCN is critical for capturing strong spatial correlations, leading to more accurate and stable predictions.
