Unlike DCGAN, CGAN is trained with explicitly provided labels which allow CGAN to associate features with specific labels. This has the intrinsic advantage of allowing us to specify the label of generated data. The baseline CGAN which we evaluate is visible in figure \ref{fig:cganarc}. The baseline CGAN architecture presents a series blocks each contained a dense layer, LeakyReLu layer (slope=0.2) and a Batch Normalisation layer. The baseline discriminator uses Dense layers, followed by LeakyReLu (slope=0.2) and a Droupout layer. +CGAN is a conditional version of a GAN which utilises labeled data. Unlike DCGAN, CGAN is trained with explicitly provided labels which allow CGAN to associate features with specific labels. This has the intrinsic advantage of allowing us to specify the label of generated data. The baseline CGAN which we evaluate is visible in figure \ref{fig:cganarc}. The baseline CGAN architecture presents a series blocks each contained a dense layer, `LeakyReLu` layer (slope=0.2) and a Batch Normalisation layer. The baseline discriminator uses Dense layers, followed by `LeakyReLu` (slope=0.2) and a Droupout layer. The optimizer used for training is `Adam`(`learning_rate=0.002`, `beta=0.5`). The Convolutional CGAN (CDCGAN) analysed follows the structure presented in the relevant Appendix section.
