If you’re diving into the world of text classification and need an efficient way to identify NSFW (Not Safe For Work) content in prompts, then the DistilRoBERTa-nsfw-prompt-stable-diffusion model is just what you need. This guide will walk you through using this model, interpreting its results, and troubleshooting any issues you may encounter along the way.

Understanding the Model

The DistilRoBERTa-nsfw-prompt-stable-diffusion model builds upon the strengths of its predecessor by leveraging a retrained dataset featuring 8 million prompts — 4 million positive samples split evenly between SFW and NSFW categories. Imagine this model as an art critic at an exhibition, where it has to categorize various artworks (prompts) as either family-friendly (SFW) or adult-themed (NSFW) based on subtle cues rather than clear labels.

How to Implement the Model

To begin using the DistilRoBERTa model, you will need to install the necessary libraries and import the dependencies. Follow these simple steps:

1. Install Required Libraries

• Make sure you have Python installed on your machine.
• Install the Hugging Face Transformers library using pip:

pip install transformers

2. Import the Model

Now, import the model and set up the prompt detector:

from transformers import pipeline

prompt_detector = pipeline("text-classification", model="AdamCoddd/distilroberta-nsfw-prompt-stable-diffusion")

3. Classify a Prompt

Next, you can use the detector to classify your prompts:

predicted_class = prompt_detector("masterpiece, 1girl, looking at viewer, sitting, tea, table, garden")
print(predicted_class)

Understanding the Results

When you run the code above, you’ll receive a classification result, For instance:

[{'label': 'SFW', 'score': 0.868}]

This output indicates that the prompt was classified as SFW with a confidence score of 86.8%. High scores close to 1 imply strong certainty in the classification.

Evaluating the Model’s Performance

The model has achieved impressive evaluation metrics, including:

• Loss: 0.2139
• Accuracy: 0.9114
• F1 Score: 0.9093
• Precision: 0.9318
• Recall: 0.8879
• ROC_AUC: 0.9716

These metrics indicate that the model’s performance has improved significantly from its predecessor, successfully reducing the occurrence of false positives.

Troubleshooting

If you encounter any issues while using this model, here are some common troubleshooting tips:

• Installation Problems: Ensure that your Python environment is set up correctly and that you have installed all required dependencies.
• Memory Errors: If you’re running into memory issues, try reducing your batch size or using a machine with more RAM.
• Model Not Found: Ensure that the model name is correctly specified. It should be “AdamCoddd/distilroberta-nsfw-prompt-stable-diffusion”.
