Model Card for Model ID

deberta-v3-base with context length of 1280 fine-tuned on tasksource for 250k steps. I oversampled long NLI tasks (ConTRoL, doc-nli). Training data include helpsteer v1/v2, logical reasoning tasks (FOLIO, FOL-nli, LogicNLI...), OASST, hh/rlhf, linguistics oriented NLI tasks, tasksource-dpo, fact verification tasks.

This checkpoint has strong zero-shot validation performance on many tasks (e.g. 70% on WNLI), and can be used for:

• Zero-shot entailment-based classification for arbitrary labels [ZS].
• Natural language inference [NLI]
• Further fine-tuning on a new task or tasksource task (classification, token classification, reward modeling or multiple-choice) [FT].

dataset	accuracy
anli/a1	63.3

Zero-shot GPT-4 scores 61% on FOLIO (logical reasoning), 62% on cladder (probabilistic reasoning) and 56.4% on ConTRoL (long context NLI).

[ZS] Zero-shot classification pipeline

from transformers import pipeline
classifier = pipeline("zero-shot-classification",model="tasksource/deberta-base-long-nli")

text = "one day I will see the world"
candidate_labels = ['travel', 'cooking', 'dancing']
classifier(text, candidate_labels)

NLI training data of this model includes label-nli, a NLI dataset specially constructed to improve this kind of zero-shot classification.

[NLI] Natural language inference pipeline

from transformers import pipeline
pipe = pipeline("text-classification",model="tasksource/deberta-base-long-nli")
pipe([dict(text='there is a cat',
  text_pair='there is a black cat')]) #list of (premise,hypothesis)
# [{'label': 'neutral', 'score': 0.9952911138534546}]

[TA] Tasksource-adapters: 1 line access to hundreds of tasks

# !pip install tasknet
import tasknet as tn
pipe = tn.load_pipeline('tasksource/deberta-base-long-nli','glue/sst2') # works for 500+ tasksource tasks
pipe(['That movie was great !', 'Awful movie.'])
# [{'label': 'positive', 'score': 0.9956}, {'label': 'negative', 'score': 0.9967}]

The list of tasks is available in model config.json. This is more efficient than ZS since it requires only one forward pass per example, but it is less flexible.

[FT] Tasknet: 3 lines fine-tuning

# !pip install tasknet
import tasknet as tn
hparams=dict(model_name='tasksource/deberta-base-long-nli', learning_rate=2e-5)
model, trainer = tn.Model_Trainer([tn.AutoTask("glue/rte")], hparams)
trainer.train()
