WFTNet: Exploiting Global and Local Periodicity in Long-term Time Series Forecasting

This is an official implementation of WFTNet: Exploiting Global and Local Periodicity in Long-term Time Series Forecasting.

Prerequisites

Ensure you are using Python 3.9 and install the necessary dependencies by running:

pip install -r requirements.txt

1. Data Preparation

Download data from AutoFormer. Put all data into a seperate folder ./dataset and make sure it has the following structure:

dataset
├── electricity
│   └── electricity.csv
├── ETT-small
│   ├── ETTh1.csv
│   ├── ETTh2.csv
│   ├── ETTm1.csv
│   └── ETTm2.csv
├── traffic
│   └── traffic.csv
└── weather
    └── weather.csv

2. Training

The training scripts for all datasets are located in the ./scripts directory.

To train a model using the ETTh1 dataset:

  1. Navigate to the repository's root directory.
  2. Execute the following command:
    sh ./scripts/ETTh1.sh

Upon completion of the training:

  • The trained model will be saved in the ./checkpoints directory.
  • Visualization outputs can be found in ./test_results.
  • Numerical results in .npy format are located in ./results.
  • A summary of the quantitative metrics is available in ./results.txt.
