# Fine-tuned ViT for House Condition Classification
|
| 16 |
+
|
| 17 |
+
This model is a fine-tuned version of [google/vit-base-patch16-224-in21k](https://huggingface.co/google/vit-base-patch16-224-in21k) for classifying house conditions into 4 categories.
|
| 18 |
+
|
| 19 |
+
## Model Description
|
| 20 |
+
|
| 21 |
+
This Vision Transformer (ViT) model has been fine-tuned to classify house images into four condition categories:
|
| 22 |
+
- **dobre** (good condition)
|
| 23 |
+
- **nepoznato** (unknown condition)
|
| 24 |
+
- **oronule** (dilapidated condition)
|
| 25 |
+
- **srednje** (medium condition)
|
| 26 |
+
|
| 27 |
+

```
|

+
|
| 63 |
+
## Usage
|
| 64 |
+
|
| 65 |
+
```python
|
| 66 |
+
from transformers import ViTForImageClassification, ViTImageProcessor
|
| 67 |
+
from PIL import Image
|
| 68 |
+
import torch
|
| 69 |
+
|
| 70 |
+
# Load model and processor
|
| 71 |
+
model = ViTForImageClassification.from_pretrained("YOUR_USERNAME/YOUR_MODEL_NAME")
|
| 72 |
+
processor = ViTImageProcessor.from_pretrained("YOUR_USERNAME/YOUR_MODEL_NAME")
|
| 73 |
+
|
| 74 |
+
# Load and preprocess image
|
| 75 |
+
image = Image.open("path_to_image.jpg").convert("RGB")
|
| 76 |
+
inputs = processor(image, return_tensors="pt")
|
| 77 |
+
|
| 78 |
+
# Make prediction
|
| 79 |
+
with torch.no_grad():
|
| 80 |
+
outputs = model(**inputs)
|
| 81 |
+
|
| 82 |
+
predicted_class_idx = outputs.logits.argmax(-1).item()
|
| 83 |
+
predicted_label = model.config.id2label[str(predicted_class_idx)]
|
| 84 |
+
|
| 85 |
+
print(f"Predicted class: {predicted_label}")
|
| 86 |
+
|
| 87 |
+
# Get probabilities
|
| 88 |
+
probs = torch.nn.functional.softmax(outputs.logits, dim=-1)[0]
|
| 89 |
+
for idx, prob in enumerate(probs):
|
| 90 |
+
label = model.config.id2label[str(idx)]
|
| 91 |
+
print(f"{label}: {prob.item():.2%}")
|
| 92 |
+
```
|
| 93 |
+
|
| 94 |
+
## Limitations and Bias
|
| 95 |
+
|
| 96 |
+
- The model was trained on a specific dataset of house images and may not generalize well to different architectural styles or regions
|
| 97 |
+
- Performance varies by class, with lower recall for the "dobre" (good condition) class
|
| 98 |
+
- The model may have difficulty distinguishing between similar condition categories
|
| 99 |
+
- Training set is relatively small (757 images)
|
| 100 |
+
|
| 101 |
+
## Training Procedure
|
| 102 |
+
|
| 103 |
+
The model was fine-tuned using the Hugging Face Transformers library with the following approach:
|
| 104 |
+
1. Pre-trained weights from google/vit-base-patch16-224-in21k were used as initialization
|
| 105 |
+
2. The classification head was replaced with a new 4-class classifier
|
| 106 |
+
3. All model parameters were fine-tuned on the custom dataset
|
| 107 |
+
4. Early stopping and checkpoint saving were employed to prevent overfitting
|
| 108 |
+
5. Images were converted to RGB to ensure consistent 3-channel input
