DAG-UPB/TS-Arena-Archive

TS-Arena Archive

This dataset contains historical time-series data from the TS-Arena. It is provided for offline model evaluation and backtesting. Additional domains (such as urban mobility) and regions will be added as they become available on the TS-Arena platform.

Evaluation Rules

Researchers using this data must follow these guidelines:

• Self-Reported Status: It must be clearly stated in any publication that results are based on self-obtained evaluation using the TS-Arena Archive and are not official rankings from the TS-Arena platform.
• Leakage Prevention: A strict temporal split must be maintained. Users are responsible for using a training dataset cutoff date strictly before the start of the evaluation period.
• Official Rankings: Inclusion in the leaderboard and future TS-Arena Archive dumps requires participation in the challenges at ts-arena.live.
