# DeBERTa-v3-small-mnli-fever-docnli-ling-2c |
|
## Model description |
|
This model was trained on 1.279.665 hypothesis-premise pairs from 8 NLI datasets: [MultiNLI](https://huggingface.co/datasets/multi_nli), [Fever-NLI](https://github.com/easonnie/combine-FEVER-NSMN/blob/master/other_resources/nli_fever.md), [LingNLI](https://arxiv.org/abs/2104.07179) and [DocNLI](https://arxiv.org/pdf/2106.09449.pdf) (which includes [ANLI](https://github.com/facebookresearch/anli), QNLI, DUC, CNN/DailyMail, Curation). |
|
|
|
It is the only model in the model hub trained on 8 NLI datasets, including DocNLI with very long texts to learn long range reasoning. Note that the model was trained on binary NLI to predict either "entailment" or "not-entailment". The DocNLI merges the classes "neural" and "contradiction" into "not-entailment" to create more training data. |
|
|
|
The base model is [DeBERTa-v3-small from Microsoft](https://huggingface.co/microsoft/deberta-v3-small). The v3 variant of DeBERTa substantially outperforms previous versions of the model by including a different pre-training objective, see annex 11 of the original [DeBERTa paper](https://arxiv.org/pdf/2006.03654.pdf) as well as the [DeBERTa-V3 paper](https://arxiv.org/abs/2111.09543). |

## Intended uses & limitations |
|
#### How to use the model |
|
```python |
|
from transformers import AutoTokenizer, AutoModelForSequenceClassification |
|
import torch |
|
|
|
model_name = "MoritzLaurer/DeBERTa-v3-small-mnli-fever-docnli-ling-2c" |
|
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", "neutral", "contradiction"] |
|
prediction = {name: round(float(pred) * 100, 1) for pred, name in zip(prediction, label_names)} |
|
print(prediction) |
|
``` |

### Training data |
|
This model was trained on 1.279.665 hypothesis-premise pairs from 8 NLI datasets: [MultiNLI](https://huggingface.co/datasets/multi_nli), [Fever-NLI](https://github.com/easonnie/combine-FEVER-NSMN/blob/master/other_resources/nli_fever.md), [LingNLI](https://arxiv.org/abs/2104.07179) and [DocNLI](https://arxiv.org/pdf/2106.09449.pdf) (which includes [ANLI](https://github.com/facebookresearch/anli), QNLI, DUC, CNN/DailyMail, Curation). |
|
|
|
### Training procedure |
|
DeBERTa-v3-small-mnli-fever-docnli-ling-2c was trained using the Hugging Face trainer with the following hyperparameters. |
|
``` |
|
training_args = TrainingArguments( |
|
num_train_epochs=3, # 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 and ANLI and the binary dev set for Fever-NLI (two classes instead of three). The metric used is accuracy. |

## Limitations and bias |
|
Please consult the original DeBERTa paper and literature on different NLI datasets for potential biases. |

|
### Debugging and issues |
|
Note that DeBERTa-v3 was released recently 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. |
