PyPOTS

简体中文 | English

⦿ Motivation: Due to all kinds of reasons like failure of collection sensors, communication error, and unexpected malfunction, missing values are common to see in time series from the real-world environment. This makes partially-observed time series (POTS) a pervasive problem in open-world modeling and prevents advanced data analysis. Although this problem is important, the area of machine learning on POTS still lacks a dedicated toolkit. PyPOTS is created to fill in this blank.

⦿ Mission: PyPOTS (pronounced "Pie Pots") is born to become a handy toolbox that is going to make machine learning on POTS easy rather than tedious, to help engineers and researchers focus more on the core problems in their hands rather than on how to deal with the missing parts in their data. PyPOTS will keep integrating classical and the latest state-of-the-art machine learning algorithms for partially-observed multivariate time series. For sure, besides various algorithms, PyPOTS is going to have unified APIs together with detailed documentation and interactive examples across algorithms as tutorials.

❖ Available Algorithms

PyPOTS supports imputation, classification, clustering, forecasting, and anomaly detection tasks on multivariate partially-observed time series with missing values. The table below shows the availability of each algorithm (sorted by Year) in PyPOTS for different tasks. The symbol ✅ indicates the algorithm is available for the corresponding task, and you could click ✅ to jump to the code example of the algorithm on the task. Note that models will be continuously updated in the future to handle tasks that are not currently supported. Stay tuned!

🌟 Since v0.2, all neural-network models in PyPOTS has got hyperparameter-optimization support by Microsoft NNI until . In PyPOTS v2, this functionality is reimplemented with the framework. You may want to refer to our time-series imputation survey and benchmark repo to see how to config and tune the hyperparameters.
