+# Unified Time Series Dataset (UTSD)
+
+## Updates
+
+:triangular_flag_on_post: **News** (2024.10) We release the numpy format of [UTSD](https://cloud.tsinghua.edu.cn/f/93868e3a9fb144fe9719/). An easier and more efficient dataloader can be found [here](https://github.com/thuml/OpenLTM/blob/main/data_provider/data_loader.py).
+
+## Introduction
+
+We curate **Unified Time Series Dataset (UTSD)** that includes **7 domains** with up to **1 billion time points** with hierarchical **four volumes** to facilitate research of large models and pre-training in the field of time series.
+
+<p align="center">
+<img src="./figures/utsd.png" alt="" align=center />
+</p>
+
+**Unified Time Series Dataset (UTSD)** is meticulously assembled from a blend of publicly accessible online data repositories and empirical data derived from real-world machine operations.
+
+All datasets are classified into seven distinct domains by their source: **Energy, Environment, Health, Internet of Things (IoT), Nature, Transportation, and Web** with diverse sampling frequencies.
+
+See this [paper](https://arxiv.org/abs/2402.02368) for more information.
+
+
+##  Usage
+
+You can access and load UTSD based on this [GitHub](https://github.com/thuml/Large-Time-Series-Model).
+
+```bash
+# huggingface-cli login
+# export HF_ENDPOINT=https://hf-mirror.com 
+
+python ./scripts/UTSD/download_dataset.py
+
+# dataloader
+python ./scripts/UTSD/utsdataset.py
+```
+
+It should be noted that due to the construction of our dataset with diverse lengths, the sequence lengths of different samples vary. You can construct the data organization logic according to your own needs.
+
+In addition, we provide code `dataset_evaluation.py` for evaluating time series datasets, which you can use to evaluate your Huggingface formatted dataset. The usage of this script is as follows:
+
+```bash
+python ./scripts/UTSD/dataset_evaluation.py --root_path <dataset root path> --log_path <output log path>
+```
+
+## Dataset Description
+
+We analyze each dataset, examining the time series through the lenses of stationarity and forecastability to allow us to characterize the level of complexity inherent to each dataset.

+##  Hierarchy of Datasets
+
+UTSD is constructed with hierarchical capacities, namely **UTSD-1G, UTSD-2G, UTSD-4G, and UTSD-12G**, where each smaller dataset is a subset of the larger ones. A larger subset means greater data **difficulty** and **diversity**, allowing you to conduct detailed scaling experiments.

+
+## Acknowledgments
+
+UTSD is mostly built from the Internet public time series dataset, which comes from different research teams and providers. We sincerely thank all individuals and organizations who have contributed the data. Without their generous sharing, this dataset would not have existed.
