# π EfficientNetV2S Poultry Feces Classifier |
|
|
|
|
|
A convolutional neural network model based on **EfficientNetV2S** for classifying chicken fecal images into 4 common conditions: |
|
|
|
|
|
* **Coccidiosis** |
|
|
* **Healthy** |
|
|
* **Newcastle Disease** |
|
|
* **Salmonella** |
|
|
|
|
|
This model is designed to support smart poultry farming by enabling early detection of diseases through image-based feces analysis. |
|
|
|
|
|
## 𧬠Model Architecture |
|
|
|
|
|
* Base: `EfficientNetV2S` (pretrained on ImageNet, frozen then fine-tuned) |
|
|
* Head: |
|
|
|
|
|
* `GlobalAveragePooling2D` |
|
|
* `Dense(128) + BatchNorm + ReLU + Dropout(0.3)` |
|
|
* `Dense(4, activation='softmax')` |
|
|
|
|
|
## π§ͺ Training & Evaluation |
|
|
|
|
|
* Optimizer: Adam |
|
|
* Loss: Categorical Crossentropy |
|
|
* Metric: Accuracy |
|
|
* Dataset: |
|
|
|
|
|
* Source: [Jayavrinda et al., 2023](https://doi.org/10.34740/KAGGLE/DS/3951043) |
|
|
* 4 classes, resized to 224x224 pixels |
|
|
* Train/Val/Test sampling (3k/400/400 per class) |
|
|
* EarlyStopping was used to monitor validation accuracy |
|
|
* Accuracy on validation set: **\~90%+** (see notebook for full results) |

## ποΈ Example Usage |
|
|
|
|
|
```python |
|
|
from tensorflow.keras.models import load_model |
|
|
import tensorflow as tf |
|
|
from PIL import Image |
|
|
import numpy as np |
|
|
|
|
|
model = load_model("path/to/your_model.h5") |
|
|
|
|
|
def preprocess(image_path): |
|
|
img = Image.open(image_path).resize((224, 224)) |
|
|
img_array = np.array(img) / 255.0 |
|
|
return np.expand_dims(img_array, axis=0) |
|
|
|
|
|
pred = model.predict(preprocess("feces.jpg")) |
|
|
class_names = ["Coccidiosis", "Healthy", "Newcastle", "Salmonella"] |
|
|
print("Prediction:", class_names[np.argmax(pred)]) |
|
|
``` |
