## Usage
|
| 14 |
+
|
| 15 |
+
### Installation
|
| 16 |
+
|
| 17 |
+
```sh
|
| 18 |
+
pip install transformers torch
|
| 19 |
+
```
|
| 20 |
+
|
| 21 |
+
### Loading the Model
|
| 22 |
+
|
| 23 |
+
```python
|
| 24 |
+
from transformers import DistilBertTokenizer, DistilBertForSequenceClassification, Trainer, TrainingArguments
|
| 25 |
+
import torch
|
| 26 |
+
|
| 27 |
+
model_name = "AventIQ-AI/distilbert-base-uncased-sentiment-analysis"
|
| 28 |
+
tokenizer = DistilBertTokenizer.from_pretrained(model_name)
|
| 29 |
+
model = DistilBertForSequenceClassification.from_pretrained(model_name)
|
| 30 |
+
|
| 31 |
+
def predict_sentiment(text):
|
| 32 |
+
inputs = tokenizer(text, return_tensors="pt", padding=True, truncation=True, max_length=512)
|
| 33 |
+
with torch.no_grad():
|
| 34 |
+
logits = model(**inputs).logits
|
| 35 |
+
predicted_class_id = torch.argmax(logits, dim=-1).item()
|
| 36 |
+
return "Positive" if predicted_class_id == 1 else "Negative"
|
| 37 |
+
|
| 38 |
+
# Test the model with a sample sentence
|
| 39 |
+
test_text = "I absolutely loved the movie! It was fantastic."
|
| 40 |
+
print(f"Sentiment: {predict_sentiment(test_text)}")
|
| 41 |
+
```
|
| 42 |
+
|
| 43 |
+
## Performance Metrics
|
| 44 |
+
|
| 45 |
+
- **Accuracy:** 0.56
|
| 46 |
+
- **F1 Score:** 0.56
|
| 47 |
+
- **Precision:** 0.68
|
| 48 |
+
- **Recall:** 0.56
|
| 49 |
+
|
| 50 |
+
## Fine-Tuning Details
|
| 51 |
+
|
| 52 |
+
### Dataset
|
| 53 |
+
|
| 54 |
+
The IMDb Reviews dataset was used, containing both positive and negative sentiment examples.
|
| 55 |
+
|
| 56 |
+
### Training
|
| 57 |
+
|
| 58 |
+
- Number of epochs: 3
|
| 59 |
+
- Batch size: 16
|
| 60 |
+
- Evaluation strategy: epoch
|
| 61 |
+
- Learning rate: 2e-5
|
| 62 |
+
|
| 63 |
+
### Quantization
|
| 64 |
+
|
| 65 |
+
Post-training quantization was applied using PyTorch's built-in quantization framework to reduce the model size and improve inference efficiency.

+
|
| 77 |
+
## Limitations
|
| 78 |
+
|
| 79 |
+
- The model may not generalize well to domains outside the fine-tuning dataset.
|
| 80 |
+
- Quantization may result in minor accuracy degradation compared to full-precision models.
