23. Convolutional Neural Network (CNN)
Convolutional Neural Networks (CNNs) are specialized deep learning models tailored for processing visual data such as images and videos. They automate the feature extraction process and address challenges presented by traditional neural networks, enhancing performance and efficiency. Widely applied in fields like face recognition and medical imaging, CNNs continue to evolve as a major component in AI-driven visual analysis.

Key Concepts
- -- Convolutional Neural Network (CNN)
- A type of artificial neural network designed for processing visual data by automatically learning features from images.
- -- Convolution Layer
- A layer in a CNN that applies filters to input images to detect patterns such as edges and textures.
- -- Pooling Layer
- A layer that reduces the dimensionality of feature maps to retain only the most significant information.
- -- ReLU Activation Function
- An activation function that introduces non-linearity into the model by converting all negative values to zero.
- -- Fully Connected Layer (FC)
- The layer that connects all neurons from one layer to every neuron in the next, typically used for classification.
- -- Applications of CNN
- Real-world uses of CNN technology include face recognition, object detection, and interpreting medical images.
