tasksource 600+ curated datasets and preprocessings for instant and interchangeable use

Huggingface Datasets is an excellent library, but it lacks standardization, and datasets often require preprocessing work to be used interchangeably. tasksource streamlines interchangeable datasets usage to scale evaluation or multi-task learning.

Each dataset is standardized to a MultipleChoice, Classification, or TokenClassification template with canonical fields. We focus on discriminative tasks (= with negative examples or classes) for our annotations but also provide a SequenceToSequence template. All implemented preprocessings are in tasks.py or tasks.md. A preprocessing is a function that accepts a dataset and returns the standardized dataset. Preprocessing code is concise and human-readable.

Installation and usage:

pip install tasksource

from tasksource import list_tasks, load_task
df = list_tasks(multilingual=False) # takes some time

for id in df[df.task_type=="MultipleChoice"].id:
    dataset = load_task(id) # all yielded datasets can be used interchangeably

Browse the 500+ curated tasks in tasks.md (200+ MultipleChoice tasks, 200+ Classification tasks), and feel free to request a new task. Datasets are downloaded to $HF_DATASETS_CACHE (like any Hugging Face dataset), so ensure you have more than 100GB of space available.

You can now also use:

load_dataset("tasksource/data", "glue/rte",max_rows=30_000)

Pretrained models:

Text encoder pretrained on tasksource reached state-of-the-art results: 🤗/deberta-v3-base-tasksource-nli

Tasksource pretraining is notably helpful for RLHF reward modeling or any kind of classification, including zero-shot. You can also find a large and a multilingual version.

tasksource-instruct

The repo also contains some recasting code to convert tasksource datasets to instructions, providing one of the richest instruction-tuning datasets: 🤗/tasksource-instruct-v0

tasksource-label-nli

We also recast all classification tasks as natural language inference, to improve entailment-based zero-shot classification detection: 🤗/zero-shot-label-nli

Write and use custom preprocessings

from tasksource import MultipleChoice

codah = MultipleChoice('question_propmt',choices_list='candidate_answers',
    labels='correct_answer_idx',
    dataset_name='codah', config_name='codah')
    
winogrande = MultipleChoice('sentence',['option1','option2'],'answer',
    dataset_name='winogrande',config_name='winogrande_xl',
    splits=['train','validation',None]) # test labels are not usable
    
tasks = [winogrande.load(), codah.load()]) #  Aligned datasets (same columns) can be used interchangably
