Dataset Overview

	hour config	min config
Granularity	1 hour	10 minutes
# test series	517	773
Series length	15,356 steps	5,904 steps
Test-set length / series	552 steps	3,312 steps
Date range	2021-11-18 → 2023-08-19	2023-07-10 → 2023-08-19
# variates / series	5	5

The 1,290 test series are stratified across all eight trend × seasonality × forecastability (TSF) regime cells (~160 series/cell), ensuring balanced evaluation.

Train/test split: Global temporal cutoff at 2023-07-28 00:00:00 UTC. Data before the cutoff is train (70%) / validation (20%); data from the cutoff onward is the test set.

Schema

Each row represents one timestamp of one series (long/tidy format).

Column	Type	Description
item_id	int64	Unique series identifier
date_time	datetime64[ns]	UTC timestamp
ind_1 … ind_5	float64	Five anonymised traffic variates (NaN for missing)

To reconstruct a single multivariate series: filter by item_id, sort by date_time, then apply the 2023-07-28 cutoff for train/test splits.

Quick Start

from datasets import load_dataset

# Load hourly test split
ds_hour = load_dataset("hq-bench/quitobench", "hour")
df_hour = ds_hour["test"].to_pandas()

# Load 10-minute test split
ds_min = load_dataset("hq-bench/quitobench", "min")
df_min = ds_min["test"].to_pandas()

Reconstruct train/test splits

import pandas as pd

CUTOFF = pd.Timestamp("2023-07-28 00:00:00")
df = load_dataset("hq-bench/quitobench", "hour")["test"].to_pandas()

# Pick one series
series = df[df["item_id"] == df["item_id"].iloc[0]].sort_values("date_time")

train = series[series["date_time"] < CUTOFF]
test  = series[series["date_time"] >= CUTOFF]

X_train = train[["ind_1", "ind_2", "ind_3", "ind_4", "ind_5"]].values
X_test  = test[["ind_1", "ind_2", "ind_3", "ind_4", "ind_5"]].values
