Direct Use

Usage

This model can be loaded and used with the Transformers library:

from transformers import AutoModelForSequenceClassification, AutoTokenizer

model_name = "your-username/your-model-name"
model = AutoModelForSequenceClassification.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)

# Example usage
text = "Only 2 items left in stock!"
inputs = tokenizer(text, return_tensors="pt")
outputs = model(**inputs)
predictions = outputs.logits.argmax(-1)

How to Get Started with the Model

from transformers import AutoModelForSequenceClassification, AutoTokenizer
import torch

class DarkPatternDetector:
    def __init__(self, model_name):
        self.label_dict = {
            0: "Urgency", 1: "Not Dark Pattern", 2: "Scarcity", 3: "Misdirection",
            4: "Social Proof", 5: "Obstruction", 6: "Sneaking", 7: "Forced Action"
        }
        self.device = 'cuda' if torch.cuda.is_available() else 'cpu'
        print(f"Using device: {self.device}")

        self.model = AutoModelForSequenceClassification.from_pretrained(model_name).to(self.device)
        self.tokenizer = AutoTokenizer.from_pretrained(model_name)

    def predict(self, text):
        inputs = self.tokenizer(text, return_tensors="pt", truncation=True, padding=True).to(self.device)
        
        with torch.no_grad():
            outputs = self.model(**inputs)
            probabilities = torch.nn.functional.softmax(outputs.logits, dim=1)
            predicted_label = torch.argmax(probabilities, dim=1).item()

        return self.label_dict[predicted_label]

# Usage
if __name__ == "__main__":
    # Replace with your Hugging Face model name
    model_name = "your-username/your-model-name"
    detector = DarkPatternDetector(model_name)

    # Example usage
    texts_to_predict = [
        "Only 2 items left in stock!",
        "This offer ends in 10 minutes!",
        "Join now and get 50% off!",
        "By clicking 'Accept', you agree to our terms and conditions."
    ]

    for text in texts_to_predict:
        result = detector.predict(text)
        print(f"Text: '{text}'\nPredicted Dark Pattern: {result}\n")

Training Details

Training Data

Metrics

Our model's performance is evaluated using the following metrics:

• Accuracy: The proportion of correct predictions among the total number of cases examined.
• Precision: The ratio of correctly predicted positive observations to the total predicted positive observations.
• Recall: The ratio of correctly predicted positive observations to all observations in the actual class.
• F1-Score: The harmonic mean of Precision and Recall, providing a single score that balances both metrics.

These metrics were chosen to provide a comprehensive view of the model's performance across different aspects of classification accuracy.

Results

Metric	Score
Accuracy	0.811881
Precision	0.808871
Recall	0.811881
F1-Score	0.796837

Our model demonstrates strong performance across all metrics:

• An accuracy of 81.19% indicates that the model correctly classifies a high proportion of samples.
• The precision of 80.89% shows that when the model predicts a specific dark pattern, it is correct about 81% of the time.
• The recall of 81.19% indicates that the model successfully identifies about 81% of the actual dark patterns in the dataset.
• An F1-Score of 79.68% represents a good balance between precision and recall.

Summary

These results suggest that the model is effective at detecting and classifying dark patterns, with a good balance between identifying true positives and avoiding false positives.
