### Result of Experiments with different styles:
**Prompt:** `"a cat and dog in the style of cs"` \
_"cs" in the prompt refers to "custom style" whose embedding is replaced by each of the concept embeddings shown below_

### Result of Experiments with Guidance loss functions:
**Prompt:** `"a mouse in the style of cs"`
**Loss Function:**
```python
def loss_fn(images):
    return images.mean()
```

```python
def loss_fn(images):
    error = (images - images.min()) / 255*(images.max() - images.min())
    return error.mean()
```

**Prompt:** `"angry german shephard in the style of cs"`
```python
def loss_fn(images):
    error1 = torch.abs(images[:, 0] - 0.9)
    error2 = torch.abs(images[:, 1] - 0.9)
    error3 = torch.abs(images[:, 2] - 0.9)
    return (
        torch.sin(error1.mean()) + torch.sin(error2.mean()) + torch.sin(error3.mean())
    ) / 3
```

        + torch.cos((error1 * error2 * error3)).mean()
    )
