Relating to or involving convolutions; in computer science, describing a mathematical operation that combines two sets of data to produce a third, commonly used in image processing and neural networks.
Formed from the noun convolution by adding the adjective suffix -al. In modern usage, the term has gained prominence through computer science, where convolutional operations process data by combining neighboring values.
Convolutional neural networks are how your phone recognizes your face—the 'convolutional' part means the computer applies the same small pattern-checker repeatedly across the image, sliding it around to catch features. It's like using a stencil many times!
