# InceptionV3 Dogs vs Cats Classifier

This repository contains a **pre-trained TensorFlow/Keras model**:  

- **File:** `InceptionV3_Dogs_and_Cats_Classification.h5`  
- **Purpose:** Binary classification of cats vs dogs images  

---

## Model Details

- **Architecture:** Transfer Learning using **InceptionV3** (pre-trained on ImageNet)  
- **Custom Classification Head:**  
  - Global Average Pooling  
  - Dense layer (512 neurons, ReLU)  
  - Dropout (0.5)  
  - Dense layer with **Sigmoid** activation for binary classification  

- **Input:** Images resized to **256 × 256** pixels  
- **Output:** Probability of "Dog" class (values close to 1 indicate dog, close to 0 indicate cat)

---

## Performance

- **Test Accuracy:** ~99%  
- Confusion matrix and ROC curves indicate excellent classification performance  
- Achieves near-perfect AUC (~1.0) on the test set

## Usage Example

```python
from tensorflow.keras.models import load_model
from PIL import Image
import numpy as np

# Load the model
model = load_model("InceptionV3_Dogs_and_Cats_Classification.h5")

# Preprocess an image
img = Image.open("cat_or_dog.jpg").resize((256, 256))
img_array = np.expand_dims(np.array(img)/255.0, axis=0)

# Predict
prediction = model.predict(img_array)
print("Dog" if prediction[0][0] > 0.5 else "Cat")
