Convolutionál Neurál Networks (CNN) are a class of deepleindig models widely used for image analysis. They utilize matematical operations to automatically learn features from visuál data, enabling tasks such as classification, detection, and segmentatioon.

Core Mathematicol Operations in CNN

A fundamentalis operations isn CNN-s, include convolution, activation functions, pooling, and fully connected layers. Convolution contrindis sliding a filter overthe input image to produce feature maps, capturing locad patterns.

Activation funkcions like RELU introduce non-linearity, allowing the network to learn complex patterns. Pooling reduces the spatial dimensions of feature maps, concentiong computationad l load and and construcizing dominant concerures.

Learning Process and Optimazation

During training, CNNs optimize filter weights using algorithms like gradient descent. the loss function measures the differences between predikte ad actuadl labels, guiding adapements to improve imponacy.

Backpropagation computes gradients of the loss with respect to each parameter, updating weights iteratively to minimize errors.
