Time Series Hub – Open Datasets & Models for Forecasting and Analysis
Time Series Hub is a community-driven initiative dedicated to advancing time series analysis through open datasets, state‑of‑the‑art models, and educational resources. We bring together researchers, practitioners, and enthusiasts working on forecasting, anomaly detection, classification, and explainability for temporal data across domains like finance, weather, energy, healthcare, and IoT.
🎯 Our Mission
- Curate and share high‑quality open datasets for time series tasks (univariate, multivariate, irregular, long‑range).
- Develop and benchmark cutting‑edge models – from classical statistical methods (ARIMA, ETS) to deep learning (LSTM, Transformers, TCNs) and foundation models (TimesFM, Chronos, Moirai).
- Provide reproducible pipelines for data preprocessing, model training, and evaluation.
- Foster a collaborative community around time series machine learning through tutorials, competitions, and open‑source contributions.
