Time Series Library (TSlib)

TSlib is an open-source library for deep learning researchers, especially deep time series analysis.

We provide a neat code base to evaluate advanced deep time series models or develop your own model, which covers five mainstream tasks: long- and short-term forecasting, imputation, anomaly detection, and classification.

🚩News (2023.09) We add a detailed tutorial for TimesNet and this library, which is quite friendly to beginners of deep time series analysis.

Leaderboard for Time Series Analysis

Till February 2023, the top three models for five different tasks are:

Model
Ranking		 Long-term
Forecasting		 Short-term
Forecasting		 Imputation Anomaly
Detection		 Classification
🥇 1st TimesNet TimesNet TimesNet TimesNet TimesNet
🥈 2nd DLinear Non-stationary
Transformer		 Non-stationary
Transformer		 Non-stationary
Transformer		 FEDformer
🥉 3rd Non-stationary
Transformer		 FEDformer Autoformer Informer Autoformer

Note: We will keep updating this leaderborad. If you have proposed advanced and awesome models, welcome to send your paper/code link to us or raise a pull request. We will add them to this repo and update the leaderborad as soon as possible.

Usage

  1. Install Python 3.8. For convenience, execute the following command.
pip install -r requirements.txt
  1. Prepare Data. You can obtained the well pre-processed datasets from [Google Drive], [Tsinghua Cloud] or [Baidu Drive]. Then place the downloaded data under the folder ./dataset. Here is a summary of supported datasets.

  1. Train and evaluate model. We provide the experiment scripts of all benchmarks under the folder ./scripts/. You can reproduce the experiment results as the following examples:
# long-term forecast
bash ./scripts/long_term_forecast/ETT_script/TimesNet_ETTh1.sh
# short-term forecast
bash ./scripts/short_term_forecast/TimesNet_M4.sh
# imputation
bash ./scripts/imputation/ETT_script/TimesNet_ETTh1.sh
# anomaly detection
bash ./scripts/anomaly_detection/PSM/TimesNet.sh
# classification
bash ./scripts/classification/TimesNet.sh
  1. Develop your own model.
  • Add the model file to the folder ./models. You can follow the ./models/Transformer.py.
  • Include the newly added model in the Exp_Basic.model_dict of ./exp/exp_basic.py.
  • Create the corresponding scripts under the folder ./scripts.
