Deberta V3 Xsmall Mnli Fever Anli Ling Binary

🚀 DeBERTa-v3-xsmall-mnli-fever-anli-ling-binary

A model trained on multiple NLI datasets for zero - shot text classification, based on the DeBERTa - v3 architecture.

🚀 Quick Start

This model is designed for zero - shot classification tasks. It was trained on binary NLI to predict either "entailment" or "not - entailment". For highest performance (but less speed), I recommend using https://huggingface.co/MoritzLaurer/DeBERTa - v3 - large - mnli - fever - anli - ling - wanli.

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch
device = torch.device("cuda") if torch.cuda.is_available() else torch.device("cpu")

model_name = "MoritzLaurer/DeBERTa-v3-xsmall-mnli-fever-anli-ling-binary"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSequenceClassification.from_pretrained(model_name)

premise = "I first thought that I liked the movie, but upon second thought it was actually disappointing."
hypothesis = "The movie was good."

input = tokenizer(premise, hypothesis, truncation=True, return_tensors="pt")
output = model(input["input_ids"].to(device))  # device = "cuda:0" or "cpu"
prediction = torch.softmax(output["logits"][0], -1).tolist()
label_names = ["entailment", "not_entailment"]
prediction = {name: round(float(pred) * 100, 1) for pred, name in zip(prediction, label_names)}
print(prediction)

✨ Features

• Trained on 782 357 hypothesis - premise pairs from 4 NLI datasets: MultiNLI, [Fever - NLI](https://github.com/easonnie/combine - FEVER - NSMN/blob/master/other_resources/nli_fever.md), LingNLI and ANLI.
• Specifically designed for zero - shot classification, predicting binary NLI results.
• Based on the DeBERTa - v3 architecture, which substantially outperforms previous versions by including a different pre - training objective.

📚 Documentation

Training data

This model was trained on 782 357 hypothesis - premise pairs from 4 NLI datasets: MultiNLI, [Fever - NLI](https://github.com/easonnie/combine - FEVER - NSMN/blob/master/other_resources/nli_fever.md), LingNLI and ANLI.

Training procedure

DeBERTa - v3 - xsmall - mnli - fever - anli - ling - binary was trained using the Hugging Face trainer with the following hyperparameters.

training_args = TrainingArguments(
    num_train_epochs=5,              # total number of training epochs
    learning_rate=2e-05,
    per_device_train_batch_size=32,   # batch size per device during training
    per_device_eval_batch_size=32,    # batch size for evaluation
    warmup_ratio=0.1,                # number of warmup steps for learning rate scheduler
    weight_decay=0.06,               # strength of weight decay
    fp16=True                        # mixed precision training
)

Eval results

The model was evaluated using the binary test sets for MultiNLI, ANLI, LingNLI and the binary dev set for Fever - NLI (two classes instead of three). The metric used is accuracy.

🔧 Technical Details

The base model is [DeBERTa - v3 - xsmall from Microsoft](https://huggingface.co/microsoft/deberta - v3 - xsmall). The v3 variant of DeBERTa substantially outperforms previous versions of the model by including a different pre - training objective, see the DeBERTa - V3 paper.

Debugging and issues

⚠️ Important Note

DeBERTa - v3 was released on 06.12.21 and older versions of HF Transformers seem to have issues running the model (e.g. resulting in an issue with the tokenizer). Using Transformers>=4.13 might solve some issues.
