Generative Adversarial Networks (GANs) have become a central topic in deep learning due to their ability to generate realistic data. This review provides an in-depth analysis of GANs, covering their introduction, taxonomy, variants, limitations, and applications. GANs consist of two main components: the generator, which creates data, and the discriminator, which evaluates the authenticity of generated data. The generator aims to produce data that the discriminator cannot distinguish from real data, while the discriminator tries to identify fake data. This adversarial process leads to the generation of high-quality data. GANs have been applied in various fields, including image generation, text-to-image synthesis, audio-to-image conversion, and video generation. They are particularly useful in detecting deepfakes and ensuring the authenticity of images, especially in social media. However, GANs face challenges such as training instability, mode collapse, and difficulty in generating diverse data. Various GAN variants have been developed to address these issues, including WGAN, C-GAN, and CycleGAN, each with unique architectures and loss functions. The review discusses the evolution of GANs from their inception in 2014 to recent advancements, highlighting key contributions and innovations. It also examines the effectiveness of GANs in different applications, such as image editing, synthesis, and enhancement. Evaluation metrics like Inception Score (IS) and Fréchet Inception Distance (FID) are used to assess GAN performance. The review also explores the role of CNNs in GANs, emphasizing their importance in image generation and manipulation. Regularization and optimization techniques are crucial for improving GAN performance, with methods like Batch Normalization, Dropout, and Adam optimization being widely used. The review also discusses the importance of ensemble learning in GANs, where multiple GANs are combined to enhance performance and stability. Additionally, it covers recent advancements in GANs, including the development of high-resolution and high-quality image generation models like BigGAN and Progressive GAN. Overall, the review highlights the significance of GANs in deep learning and their potential for future research and applications. It provides a comprehensive overview of GANs, their variants, and their applications, emphasizing the need for further research to address existing challenges and improve performance.Generative Adversarial Networks (GANs) have become a central topic in deep learning due to their ability to generate realistic data.
