DLFormer: Enhancing Explainability in Multivariate Time Series Forecasting using Distributed Lag Embedding

no code implementations29 Aug 2024 Younghwi Kim, Dohee Kim, Sunghyun Sim

Although attention-based models have limitations in representing the individual influences of each variable, these models can influence the temporal dependencies in time series prediction and the magnitude of the influence of individual variables.

Correlation recurrent units: A novel neural architecture for improving the predictive performance of time-series data

no code implementations30 Nov 2022 Sunghyun Sim, Dohee Kim, Hyerim Bae

However, because this approach is learned in an independent model for each component, it cannot learn the relationships between time-series components.
