📝 Introduction

Image classification is the process of identifying and categorizing objects in an image. In this project, we use two types of neural networks:

• ANN (Artificial Neural Network): A basic model for image classification.
• CNN (Convolutional Neural Network): A more advanced model that captures image-specific features for better accuracy.

---

💾 Dataset

We use the CIFAR-10 dataset, which contains:

• 60,000 images divided into 10 categories: airplane, automobile, bird, cat, deer, dog, frog, horse, ship, truck.
• Images are 32x32 pixels with 3 color channels (RGB).

---

💻 Technologies Used

• Python: Programming language.
• TensorFlow/Keras: Framework for building and training neural networks.
• Matplotlib: Library for data visualization.
• NumPy: Library for numerical computations.

⚡ Code Explanation

1. Data Preprocessing:

   • Normalize pixel values to range [0, 1] for faster and stable training.
   • Reshape labels to make them compatible with the models.

2. ANN Model:

   • A simple architecture with fully connected layers.
   • Output layer uses a softmax activation function to predict probabilities for 10 classes.

3. CNN Model:

   • Includes convolutional and pooling layers to extract features from images.
   • Improves classification accuracy compared to ANN.

4. Evaluation:

   • Evaluate models using test data and generate classification reports.

😃 Results

Model	Accuracy
ANN	~49%
CNN	~70%

Conclusion

• ANN is suitable for simple datasets but lacks accuracy for images.
• CNN performs better due to its ability to extract spatial hierarchies (e.g., edges, textures).
• Image classification is an essential task in AI, with applications in self-driving cars, medical diagnostics, and more.

---

Future Work

• Use data augmentation to improve accuracy.
• Experiment with deeper networks or transfer learning using pre-trained models.
• Apply this framework to a custom dataset for real-world applications.
