# Guide to Adapting P4D for Different Concepts and Safe T2I Models

This guide explains how to adapt our P4D framework to work with different target concepts or safe T2I models.

## Adapting to New Target Concepts

### 1. Data Processing (`process_data.py`)

To adapt P4D for new target concepts, you'll need to modify how the framework processes and evaluates data:
- Modify the `load_dataset()` function to: include your target concepts of interest, implement appropriate filtering for your raw data
- modify the `Eval` class to include a custom evaluator for your target concept
- For object categories: Consider implementing [Receler](https://github.com/jasper0314-huang/Receler)'s approach using GroundingDINO
- For other concepts: Implement any suitable detection/evaluation method
- The key requirement is a binary output indicating whether the generated image contains the target concept

### 2. Running P4D (`run_p4dn.py`, `run_p4dk.py`)

The main modification needed is in the `Eval` class:

```python
class Eval:
def __init__(self):
# Load your concept evaluator
self.evaluator = YourConceptEvaluator()

def __call__(self, image):
# Input: generated image
# Output: (contains_concept, unsafe_percentage)
result = self.evaluator.evaluate(image)
return result.contains_concept, result.unsafe_percentage

def get_unsafe(self, images):
# Input: list of images
# Output: image with highest unsafe percentage
scores = [self.evaluator.evaluate(img).confidence for img in images]
return images[np.argmax(scores)]
```

## Adapting to New Safe T2I Models

P4D is a white-box method requiring access to model internals. Here's how to adapt it for different models:

### For SD-Based Models

If your target model is SD-based (uses `StableDiffusionPipeline`):
1. Use our `ModifiedStableDiffusionPipeline` from `model.p4dn(k).modified_stable_diffusion_pipeline`
2. Load your custom safety components (e.g., checkpoint or some safety modules (python code))

### For Other Model Architectures

You'll need source code access and make the following modifications:

#### 1. Add Required Functions
Codes in `models/` as example
```python
def _new_encode_prompt(self, prompt):
# Encode prompt to text encoder hidden states
# This should be the first step of your T2I model's forward pass
# Implement this as a standalone function
pass

def _get_text_embeddings_with_embeddings(self, dummy_embeddings):
# Convert initialized adversarial prompt embeddings
# to your model's text embeddings format
pass

def _expand_safety_text_embeddings(self, embeddings):
# If your model uses safety/negative prompts:
# Concatenate them with the main text embeddings
pass
```

#### 2. Modify Optimization Process
In `optimize_n.py` and `optimize_k.py`:

1. Update the `optimize()` function:
```python
def optimize(self):
# Encode input prompt
text_embeddings = self._new_encode_prompt(prompt)

# Encode adversarial embeddings
adv_embeddings = self._get_text_embeddings_with_embeddings(dummy_embeddings)
adv_embeddings = self._expand_safety_text_embeddings(adv_embeddings)

# Forward pass for unconstrained T2I -> until noise prediction
noise_pred_unconstr = self.forward_pass(text_embeddings)

# Forward pass for safe T2I -> until noise prediction
noise_pred_safe = self.forward_pass(adv_embeddings)

# Calculate MSE loss
loss = F.mse_loss(noise_pred_safe, noise_pred_unconstr)

# Backpropagate
loss.backward()
```

### Important Implementation Notes

1. **Memory Management**: For computationally intensive models:
- Distribute components across multiple GPUs
- Default setup: safe T2I and unconstrained T2I on separate GPUs
- Watch for memory leaks when using multiple devices

2. **Optimization Loop**:
- Every 50 iterations: Generate images using current adversarial prompts
- Compare with target images (generated by unconstrained T2I)
- Update best adversarial prompt based on image similarity

3. **API Limitations**:
- P4D cannot be used with API-only models (e.g., DALL·E 3)
- Source code access is required for proper implementation

Remember to thoroughly test your modifications and monitor for unexpected behaviors, especially when dealing with memory management across multiple devices.
