# MiniLM-L6-mnli-binary
|
| 14 |
+
## Model description
|
| 15 |
+
This model was trained on the [MultiNLI](https://huggingface.co/datasets/multi_nli) dataset. The model was trained for binary NLI, which means that the "neutral" and "contradiction" classes were merged into one class. The model therefore predicts "entailment" or "not_entailment".
|
| 16 |
+
The base model is MiniLM-L6 from Microsoft, which is very fast, but a bit less accurate than other models.
|
| 17 |
+
|
| 18 |
+
## Intended uses & limitations
|
| 19 |
+
#### How to use the model
|
| 20 |
+
```python
|
| 21 |
+
from transformers import AutoTokenizer, AutoModelForSequenceClassification
|
| 22 |
+
import torch
|
| 23 |
+
|
| 24 |
+
model_name = "MoritzLaurer/MiniLM-L6-mnli-binary"
|
| 25 |
+
tokenizer = AutoTokenizer.from_pretrained(model_name)
|
| 26 |
+
model = AutoModelForSequenceClassification.from_pretrained(model_name)
|
| 27 |
+
|
| 28 |
+
premise = "I liked the movie"
|
| 29 |
+
hypothesis = "The movie was good."
|
| 30 |
+
|
| 31 |
+
input = tokenizer(premise, hypothesis, truncation=True, return_tensors="pt")
|
| 32 |
+
output = model(input["input_ids"].to(device)) # device = "cuda:0" or "cpu"
|
| 33 |
+
prediction = torch.softmax(output["logits"][0], -1).tolist()
|
| 34 |
+
label_names = ["entailment", "neutral", "contradiction"]
|
| 35 |
+
prediction = {name: round(float(pred) * 100, 1) for pred, name in zip(prediction, label_names)}
|
| 36 |
+
print(prediction)
|
| 37 |
+
```
|
| 38 |
+
### Training data
|
| 39 |
+
[MultiNLI](https://huggingface.co/datasets/multi_nli).
|
| 40 |
+
|
| 41 |
+
### Training procedure
|
| 42 |
+
MiniLM-L6-mnli-binary was trained using the Hugging Face trainer with the following hyperparameters.
|
| 43 |
+
```
|
| 44 |
+
training_args = TrainingArguments(
|
| 45 |
+
num_train_epochs=5, # total number of training epochs
|
| 46 |
+
learning_rate=2e-05,
|
| 47 |
+
per_device_train_batch_size=32, # batch size per device during training
|
| 48 |
+
per_device_eval_batch_size=32, # batch size for evaluation
|
| 49 |
+
warmup_ratio=0.1, # number of warmup steps for learning rate scheduler
|
| 50 |
+
weight_decay=0.06, # strength of weight decay
|
| 51 |
+
fp16=True # mixed precision training
|
| 52 |
+
)
|
| 53 |
+
```
|
| 54 |
+
### Eval results
|
| 55 |
+
The model was evaluated using the binary (matched) test set from MultiNLI. Accuracy: 0.886
|
| 56 |
+
|
| 57 |
+
## Limitations and bias
|
| 58 |
+
Please consult the original MiniLM paper and literature on different NLI datasets for potential biases.
|
| 59 |
+
