# Duplicate Sentence Detection with ALBERT-base-v2
|
2 |
+
|
3 |
+
## π Overview
|
4 |
+
|
5 |
+
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.

16 |
+
|
17 |
+
### Installation
|
18 |
+
|
19 |
+
```bash
|
20 |
+
pip install transformers torch
|
21 |
+
```
|
22 |
+
|
23 |
+
### Loading the Model
|
24 |
+
|
25 |
+
```python
|
26 |
+
from transformers import AlbertTokenizer, AlbertForSequenceClassification
|
27 |
+
import torch
|
28 |
+
|
29 |
+
device = "cuda" if torch.cuda.is_available() else "cpu"
|
30 |
+
|
31 |
+
model_name = "AventIQ-AI/albert-duplicate-sentence-detection"
|
32 |
+
model = AlbertForSequenceClassification.from_pretrained(model_name).to(device)
|
33 |
+
tokenizer = AlbertTokenizer.from_pretrained(model_name)
|
34 |
+
```
|
35 |
+
|
36 |
+
### Paraphrase Detection Inference
|
37 |
+
|
38 |
+
```python
|
39 |
+
def predict_duplicate(question1, question2, model):
|
40 |
+
inputs = tokenizer(question1, question2, truncation=True, padding="max_length", max_length=128, return_tensors="pt")
|
41 |
+
|
42 |
+
# β
Move inputs to the same device as the model
|
43 |
+
inputs = {key: value.to(device) for key, value in inputs.items()}
|
44 |
+
|
45 |
+
with torch.no_grad(): # Disable gradient calculation
|
46 |
+
outputs = model(**inputs)
|
47 |
+
logits = outputs.logits
|
48 |
+
|
49 |
+
# β
Get prediction
|
50 |
+
probs = torch.softmax(logits, dim=1)
|
51 |
+
prediction = torch.argmax(probs, dim=1).item()
|
52 |
+
|
53 |
+
# β
Output the results
|
54 |
+
label_map = {0: "Not Duplicate", 1: "Duplicate"}
|
55 |
+
print(f"Q1: {question1}")
|
56 |
+
print(f"Q2: {question2}")
|
57 |
+
print(f"Prediction: {label_map[prediction]} (Confidence: {probs.max().item():.4f})\n")
|
58 |
+
|
59 |
+
# π Test Example
|
60 |
+
test_samples = [
|
61 |
+
("How can I learn Python quickly?", "What is the fastest way to learn Python?"), # Duplicate
|
62 |
+
("What is the capital of India?", "Where is New Delhi located?"), # Duplicate
|
63 |
+
("How to lose weight fast?", "What is the best programming language to learn?"), # Not Duplicate
|
64 |
+
("Who is the CEO of Tesla?", "What is the net worth of Elon Musk?"), # Not Duplicate
|
65 |
+
("What is machine learning?", "How does AI work?"), # Duplicate
|
66 |
+
]
|
67 |
+
for q1, q2 in test_samples:
|
68 |
+
predict_duplicate(q1, q2, model)
|
69 |
+
```

## β‘ Quantization Details
|
81 |
+
|
82 |
+
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
|
95 |
+
|
96 |
+
- The model may struggle with highly nuanced paraphrases.
|
97 |
+
- Quantization may lead to slight degradation in accuracy compared to full-precision models.
|
98 |
+
- Performance may vary across different domains and sentence structures.
