 specific issue is solved by training the network for more epochs or introducing a deeper architecture, as it can be deducted from a qualitative comparison

 Applying Virtual Batch Normalization on Medium DCGAN does not provide observable changes in G-D balancing, but reduces within-batch correlation. Although it 
 is difficult to qualitatively assess the improvements, figure \ref{fig:vbn_dc} shows results of the introduction of this technique.

+We evaluated the effect of different dropout rates (results in appendix, figures \ref{dcdrop1_1}, \ref{dcdrop1_2}, \ref{dcdrop2_1}, \ref{dcdrop2_2}) and concluded that the optimization
+of this parameter is essential to obtain good performance: a high dropout rate would result in DCGAN producing only artifacts that do not really match any specific class due to the generator performing better than the discriminator. Conversely a low dropout rate would lead to an initial stabilisation of G-D losses, but it would result into oscillation when training for a large number of epochs.
