Abstract

Generative models in AI are an entirely new paradigm for machine learning, allowing computers to create realistic data in all kinds of categories, like text (NLP), images, and even physics simulations. In this paper this formalism is used to guide the theory, algorithms and applications of generative models, with particular focus on a few well established techniques like VAEs, GANs, and diffusion models. It stresses the importance of probabilistic generative modelling and information theory (I.e. KL divergence, ELBO, adversarial optimization, etc.) We cover algorithmic practices such as optimization techniques, multimodal and conditional generation, and efficient data-driven strategies, demonstrating the impact of these methods in various real-world applications including text, image, and audio generation, industrial design, and scientific discovery. However, the fields are still grappling with significant challenges — training instability, the need for huge computational resources, and a lack of consistent, unified treatment across applications. The paper finishes with an optimistic vision of what the future has to hold, such as finding more sample efficient ways to learn, architectures to facilitate scalability on a global scale, and cohesive theoretical frameworks to bring out the very best in generative AI. By combining this theoretical understanding with practical implications, this paper will explore generative AI technologies and their potential to transform whole industries and scientific disciplines.
