TSlib is an open-source library for deep learning researchers, especially for deep time series analysis.
We provide a neat code base to evaluate advanced deep time series models or develop your model, which covers five mainstream tasks: long- and short-term forecasting, imputation, anomaly detection, and classification.
🚩News (2024.04) Many thanks for the great work from frecklebars. The famous sequenctial model Mamba has been included in our library. See this file, where you need to install mamba_ssm with pip at first.
🚩News (2024.03) Given the inconsistent look-back length of various papers, we split the long-term forecasting in the leaderboard into two categories: Look-Back-96 and Look-Back-Searching. We recommend researchers read TimeMixer, which includes both settings of the look-back length into experiments for scientific rigor.
🚩News (2023.10) We add an implementation to iTransformer, which is the state-of-the-art model for long-term forecasting. The official code and complete scripts of iTransformer can be found here.
🚩News (2023.09) We added a detailed tutorial for TimesNet and this library, which is quite friendly to beginners of deep time series analysis.
🚩News (2023.02) We release the TSlib as a comprehensive benchmark and code base for time series models, which is extended from our previous GitHub repository Autoformer.
Till March 2024, the top three models for five different tasks are:
| Model Ranking |
Long-term Forecasting Look-Back-96 |
Long-term Forecasting Look-Back-Searching |
Short-term Forecasting |
Imputation | Classification | Anomaly Detection |
|---|---|---|---|---|---|---|
| 🥇 1st | iTransformer | TimeMixer | TimesNet | TimesNet | TimesNet | TimesNet |
| 🥈 2nd | TimeMixer | PatchTST | Non-stationary Transformer |
Non-stationary Transformer |
Non-stationary Transformer |
FEDformer |
| 🥉 3rd | TimesNet | DLinear | FEDformer | Autoformer | Informer | Autoformer |
Note: We will keep updating this leaderboard. If you have proposed advanced and awesome models, you can send us your paper/code link or raise a pull request. We will add them to this repo and update the leaderboard as soon as possible.
