“…There are various metrics used to measure the divergence between the probability distributions, including Jensen–Shannon (JS) divergence (Goodfellow et al, 2014), Wasserstein distance (Arjovsky et al, 2017), and maximum mean discrepancy (MMD; Huang et al, 2021). The diversity of the objective functions leads to several extensions of GANs like Wasserstein GAN (WGAN; Arjovsky et al, 2017), LSGAN (Mao et al, 2017), Cramér GAN (Bellemare et al, 2017), f‐GAN (Nowozin et al, 2016), AlphaGAN (Y. Tian et al, 2020), and ‐GAN (Gnanha et al, 2022). On the other side, different validation metrics are used to judge the quality and diversity of the generated synthetic data.…”
