Check out the new article: Neural Networks in Trading: Dual Time Series Clustering (DUET).
Existing data processing methods can be divided into three categories. The first approach involves analyzing each channel independently, but this ignores relationships between variables. The second approach combines all channels; however, this may introduce redundant information and reduce accuracy. The third approach is variable clustering, but it limits the flexibility of the model.
To address these issues, the authors of the paper "DUET: Dual Clustering Enhanced Multivariate Time Series Forecasting" proposed the DUET method, which combines two types of clustering: temporal and channel clustering. Temporal clustering (TCM) groups data based on similar characteristics and allows models to adapt to changes over time. In financial market analysis, this makes it possible to account for different phases of economic cycles. Channel clustering (CCM) identifies key variables, removing noise and improving forecasting accuracy. It reveals stable relationships between assets, which is particularly important for constructing diversified investment portfolios.
Afterward, the results are integrated by the Fusion Module (FM), which synchronizes information about temporal patterns and cross-channel dependencies. This approach enables more accurate forecasting of complex systems such as financial markets. Experiments conducted by the authors of the framework demonstrated that DUET outperforms existing methods, providing more accurate forecasts. It accounts for heterogeneous temporal patterns and the dynamics of cross-channel relationships, adapting to data variability.
