A Convolutional Neural Network (CNN) is a type of artificial neural network primarily designed for processing and analyzing visual data, particularly images. It has proven highly effective in tasks like image classification, object detection, facial recognition, and more. 

Generative AI refers to a class of neural network models, such as the Transformer architecture, used in generative tasks. The Transformer architecture revolutionized sequence modeling tasks, especially in natural language processing (NLP) and generative tasks like language translation, text generation, and image generation.
