The official implementation of paper "Disentangled Parameter-Efficient Linear Model for Long-Term Time Series Forecasting" (DASFAA 2026)

We recommend using the latest versions of dependencies. However, you can refer to the environment.yml file to set up the same environment as we used.

All datasets are stored as CSV files and compressed in GZ format. Please place the datasets in the ./dataset directory.

• For the M5 dataset, we recommend downloading it from M5-methods and preprocessing it using preprocessing/M5.py.
• For other datasets, we recommend downloading them from Autoformer.

All experiments can be reproduced using the scripts/DiPE.sh script.
