Salesforce/GiftEvalParquet

GiftEval Parquet Collection

This repository hosts the parquet formatted GiftEval test data for ease of evaluating with LLM backboned models. Each dataset in the original GiftEval dataset can be loaded separately using the config names: datasetName_freq_term. Each row is a sample window from the test split of data, generated using the original GiftEval proressing script.

Each entry contains the following fields:

• item_id (string): e.g. "item_0_dim0_window0/2018-04-12 20:00:00"
• frequency (string): e.g. "15T"
• history_start (string): e.g. "2016-07-01 00:00:00"
• history_end (string): e.g. "2018-04-12 19:45:00"
• history_value (list): e.g. [1,3,3,4,5,6,7,...]
• future_start (string): e.g. "2018-04-12 20:00:00"
• future_end (string): e.g. "2018-04-20 07:45:00"
• future_value (list): e.g. [8,9,10,...]
• config (string): e.g. "ett1/15T/long"

Note: that multivariate datasets are split into univariate form so each row is a univariate sample. The dimension information is saved within item_id.

Example usage

  from datasets import load_dataset

  ds = load_dataset(
      "Salesforce/GiftEvalParquet",
      "bitbrains_fast_storage_5T_long",
      split="train"
  )
  print(len(ds))
  print(ds[0].keys())
