Model Card for DeBERTa-v3-small-tasksource-nli
DeBERTa-v3-small with context length of 1680 tokens 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 model is suitable for long context NLI or as a backbone for reward models or classifiers fine-tuning.
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 or multiple-choice) [FT].

[ZS] Zero-shot classification pipeline
from transformers import pipeline
classifier = pipeline("zero-shot-classification",model="tasksource/deberta-small-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-small-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}]

Software and training details
The model was trained on 600 tasks for 250k steps with a batch size of 384 and a peak learning rate of 2e-5. Training took 14 days on Nvidia A30 24GB gpu. This is the shared model with the MNLI classifier on top. Each task had a specific CLS embedding, which is dropped 10% of the time to facilitate model use without it. All multiple-choice model used the same classification layers. For classification tasks, models shared weights if their labels matched.
