๐ŸŒŸ Contributions

  • To the best of our knowledge, KARMA is the first framework to integrate Mamba with multi-level decomposition for multi-scaled hybrid frequency-temporal analysis, fully leveraging Mamba's potential to overcome the limitations of Transformer architectures and existing decomposition methods for efficient time series forecasting.
  • We propose ATCD for dynamic seasonal-trend decomposition and HFTD for hybrid frequency-temporal analysis, enabling the effective utilization of latent information in time series data and improving predictive accuracy.
  • Comprehensive experiments on eight real-world datasets across various domains demonstrate that KARMA achieves state-of-the-art performance in most benchmarks.
