## Usage
|
25 |
+
This model can be loaded and used with Hugging Face's `transformers` library:
|
26 |
+
|
27 |
+
```python
|
28 |
+
from transformers import AutoTokenizer, AutoModelForSequenceClassification
|
29 |
+
import torch
|
30 |
+
|
31 |
+
# Load the model and tokenizer
|
32 |
+
tokenizer = AutoTokenizer.from_pretrained("your-username/DistilBERT-PhishGuard")
|
33 |
+
model = AutoModelForSequenceClassification.from_pretrained("your-username/DistilBERT-PhishGuard")
|
34 |
+
|
35 |
+
# Sample URL for classification
|
36 |
+
url = "http://example.com"
|
37 |
+
inputs = tokenizer(url, return_tensors="pt", truncation=True, max_length=256)
|
38 |
+
outputs = model(**inputs)
|
39 |
+
predictions = torch.argmax(outputs.logits, dim=-1)
|
40 |
+
print("Prediction:", "Phishing" if predictions.item() == 1 else "Safe")
|
41 |
+
|
42 |
+
## Performance
|
43 |
+
The model achieves high accuracy across different chunks of training data, with performance metrics above 98% accuracy and an AUC close to or at 1.00 in later stages. This indicates robust and reliable phishing detection across varied datasets.
|
44 |
+
|
45 |
+
## Limitations and Biases
|
46 |
+
The model's performance may degrade on URLs containing obfuscated or novel phishing techniques.
|
47 |
+
It may be less effective on non-English URLs and may need further fine-tuning for different languages or domain-specific URLs.
|
