Convolutional Neural Networks (CNNs)
See how computers "see". Apply filters (kernels) to extract features like edges and patterns from images. This operation is the core building block of modern computer vision.

🔍 Convolution
The kernel slides across the image, computing a weighted sum at each position. Different kernels detect different features — edges, textures, gradients, and more.
⚡ ReLU Activation
Rectified Linear Unit sets all negative values to zero. This introduces non-linearity, allowing the network to learn complex patterns beyond simple linear filters.
📐 Max Pooling
Reduces spatial dimensions by taking the maximum value in each 2×2 region. This makes the features translation-invariant and reduces computational cost.
