# Duplicate Sentence Detection with ALBERT-base-v2 |
|
|
|
## π Overview |
|
|
|
This repository hosts the quantized version of the ALBERT-base-v2 model for Duplicate Sentence Detection. The model is designed to determine whether two sentences convey the same meaning. If they are similar, the model outputs "duplicate" with a confidence score; otherwise, it outputs "not duplicate" with a confidence score. The model has been optimized for efficient deployment while maintaining reasonable accuracy, making it suitable for real-time applications. |

## π Usage |
|
|
|
### Installation |
|
|
|
```bash |
|
pip install transformers torch |
|
``` |
|
|
|
### Loading the Model |
|
|
|
```python |
|
from transformers import AlbertTokenizer, AlbertForSequenceClassification |
|
import torch |
|
|
|
device = "cuda" if torch.cuda.is_available() else "cpu" |
|
|
|
model_name = "AventIQ-AI/albert-duplicate-sentence-detection" |
|
model = AlbertForSequenceClassification.from_pretrained(model_name).to(device) |
|
tokenizer = AlbertTokenizer.from_pretrained(model_name) |
|
``` |
|
|
|
### Paraphrase Detection Inference |
|
|
|
```python |
|
def predict_duplicate(question1, question2, model): |
|
inputs = tokenizer(question1, question2, truncation=True, padding="max_length", max_length=128, return_tensors="pt") |
|
|
|
# β
Move inputs to the same device as the model |
|
inputs = {key: value.to(device) for key, value in inputs.items()} |
|
|
|
with torch.no_grad(): # Disable gradient calculation |
|
outputs = model(**inputs) |
|
logits = outputs.logits |
|
|
|
# β
Get prediction |
|
probs = torch.softmax(logits, dim=1) |
|
prediction = torch.argmax(probs, dim=1).item() |
|
|
|
# β
Output the results |
|
label_map = {0: "Not Duplicate", 1: "Duplicate"} |
|
print(f"Q1: {question1}") |
|
print(f"Q2: {question2}") |
|
print(f"Prediction: {label_map[prediction]} (Confidence: {probs.max().item():.4f})\n") |
|
|
|
# π Test Example |
|
test_samples = [ |
|
("How can I learn Python quickly?", "What is the fastest way to learn Python?"), # Duplicate |
|
("What is the capital of India?", "Where is New Delhi located?"), # Duplicate |
|
("How to lose weight fast?", "What is the best programming language to learn?"), # Not Duplicate |
|
("Who is the CEO of Tesla?", "What is the net worth of Elon Musk?"), # Not Duplicate |
|
("What is machine learning?", "How does AI work?"), # Duplicate |
|
] |
|
for q1, q2 in test_samples: |
|
predict_duplicate(q1, q2, model) |
|
``` |

## β‘ Quantization Details |
|
|
|
Post-training quantization was applied using PyTorch's built-in quantization framework. The model was quantized to Float16 (FP16) to reduce model size and improve inference efficiency while balancing accuracy. |

|
## β οΈ Limitations |
|
|
|
- The model may struggle with highly nuanced paraphrases. |
|
- Quantization may lead to slight degradation in accuracy compared to full-precision models. |
|
- Performance may vary across different domains and sentence structures. |
