Even though Artificial Intelligence is advancing, artificial intelligence can still find it difficult to solve problems that are easy for humans to do but difficult for computers to describe, such as facial recognition. There are problems related to the existing facial recognition model, namely the facial recognition model. The model is still unable to recognize facial shapes that are not in a perfect state due to several factors. Among several factors, the most influencing factor is the position of the face. Therefore, in this study, Deep Convolutional Generative Adversarial Networks (DCGAN) will be applied to generate fake image data with varying face positions. This research will be carried out starting from collecting data, processing data, designing, and training models, hyperparameter tuning, and lastly analyzing test results. Based on the results of hyperparameter tuning that carried out sequentially, the best hyperparameter combination produced is 200 epoch, 0.002 Generator learning rate, 0.5 Generator momentum/beta1, Adam as Generator optimizer, 0.0002 Discriminator learning rate, 0.5 Discriminator momentum/beta1, and Adam as Discriminator optimizer. The hyperparameter combination gives a result with FID score of 74.05. Based on testing with human observer, generated fake images has relatively good results, but there are still few bad fake image results. © 2023, Ikatan Ahli Informatika Indonesia.
