Introduction to Convolutional Neural Networks (CNNs) 🧠

Convolutional Neural Networks (CNNs) are a class of deep learning algorithms primarily used for image recognition and computer vision tasks. Their ability to automatically learn spatial hierarchies from data makes them highly effective in processing visual information.

Key Components of CNNs 🛠️

  1. Input Layer
    The input layer receives raw pixel data from images.

  2. Convolutional Layers
    These layers apply filters to detect features like edges, textures, and patterns.

  3. Activation Functions
    Non-linear functions (e.g., ReLU) introduce complexity to model real-world data.

  4. Pooling Layers
    Used for reducing spatial dimensions while retaining important features.

  5. Fully Connected Layers
    These layers classify the extracted features into final outputs.

Applications 🌐

  • Image Classification (e.g., identifying objects in photos)
  • Object Detection (e.g., locating cars in video frames)
  • Image Segmentation (e.g., medical imaging analysis)
  • Natural Language Processing (e.g., text classification with CNNs)
