Overview

GIFT-Eval is a benchmark for general time-series forecasting, covering 23 datasets (≈144,000 series and 177M data points) across seven domains, ten frequencies, and a range of forecast horizons. This repository contains a single subset of that benchmark.

car_parts_with_missing — Monthly car-parts sales demand series (Monash), including missing values.

All .tsfile files are stored under data/.

Schema (TsFile structure)

• Time (INT64, milliseconds) — the timestamp of each observation.
• Each series is stored as a TsFile device; per-series identifiers from GIFT-Eval are carried as TAG columns, and the observed values are FIELD columns.

Usage

Read the .tsfile files with the Apache TsFile Java or Python SDK.
