论文摘要
统计信号处理和机器学习中最重要的挑战之一是如何获得可以生成大规模数据分布样本(例如图像和语音)样本的生成模型。生成对抗网络(GAN)是解决此问题的有效方法。甘斯提供了一种适当的方法来学习深层表示,而无需广泛使用标记的培训数据。这种方法吸引了许多研究人员在计算机视觉中的注意力,因为它可以生成大量数据,而无需精确建模概率密度函数(PDF)。在GAN中,生成模型是通过竞争过程估算的,在该过程中,生成器和判别网络同时训练。发电机学会了生成合理的数据,并且歧视器学会区分发电机创建的假数据与真实数据示例。鉴于过去几年的甘斯快速增长及其在各个领域的应用,有必要准确调查这些网络。在本文中,在介绍了主要概念和甘恩理论之后,比较了两个新的深层生成模型,在文献中使用的评估指标和gan的挑战也得到了解释。此外,对最杰出的gan体系结构进行了分类和讨论。最后,检查了计算机视觉中的基本应用。
One of the most significant challenges in statistical signal processing and machine learning is how to obtain a generative model that can produce samples of large-scale data distribution, such as images and speeches. Generative Adversarial Network (GAN) is an effective method to address this problem. The GANs provide an appropriate way to learn deep representations without widespread use of labeled training data. This approach has attracted the attention of many researchers in computer vision since it can generate a large amount of data without precise modeling of the probability density function (PDF). In GANs, the generative model is estimated via a competitive process where the generator and discriminator networks are trained simultaneously. The generator learns to generate plausible data, and the discriminator learns to distinguish fake data created by the generator from real data samples. Given the rapid growth of GANs over the last few years and their application in various fields, it is necessary to investigate these networks accurately. In this paper, after introducing the main concepts and the theory of GAN, two new deep generative models are compared, the evaluation metrics utilized in the literature and challenges of GANs are also explained. Moreover, the most remarkable GAN architectures are categorized and discussed. Finally, the essential applications in computer vision are examined.
