📄 What's Inside

• Dog_vs_Cat_CNN.ipynb
  Jupyter Notebook containing the full code for:

  • Loading and preprocessing image data
  • Creating and training the CNN model
  • Evaluating accuracy and loss
  • Making predictions on test data

• dataset/
  Contains training and test images of dogs and cats, typically structured as:

  dataset/
    └── train/
        ├── cats/
        └── dogs/
    └── test/

🧠 How It Works

1. Data Preparation
   Images are resized and normalized. They are labeled automatically based on directory structure (cats/ or dogs/).

2. Model Architecture
   A basic CNN with convolutional, max-pooling, and dense layers. Compiled with binary_crossentropy loss for binary classification.

3. Training
   Model is trained over multiple epochs, with accuracy and loss visualized using plots.

4. Prediction
   Custom images can be passed through the model to predict if it's a dog or a cat.
