Rowel Atienza

Rowel Atienza is an Associate Professor at the Electrical and Electronics Engineering Institute of the University of the Philippines, Diliman. He holds the Dado and Maria Banatao Institute Professorial Chair in Artificial Intelligence. Rowel has been fascinated with intelligent robots since he graduated from the University of the Philippines. He received his MEng from the National University of Singapore for his work on an AI-enhanced four-legged robot. He finished his Ph.D. at The Australian National University for his contribution on the field of active gaze tracking for human-robot interaction. Rowel's current research work focuses on AI and computer vision. He dreams on building useful machines that can perceive, understand, and reason. To help make his dreams become real, Rowel has been supported by grants from the Department of Science and Technology (DOST), Samsung Research Philippines, and Commission on Higher Education-Philippine California Advanced Research Institutes (CHED-PCARI).

Conditional GAN


In the previous section, the fake images generated by the DCGAN are random. There is no control over which specific digits will be produced by the generator. There is no mechanism for how to request a particular digit from the generator. This problem can be addressed by a variation of GAN called Conditional GAN (CGAN) [4].

Using the same GAN, a condition is imposed on both the generator and discriminator inputs. The condition is in the form of a one-hot vector version of the digit. This is associated with the image to produce (generator) or classified as real or fake (discriminator). The CGAN model is shown in Figure 4.3.1.

CGAN is similar to DCGAN except for the additional one-hot vector input. For the generator, the one-hot label is concatenated with the latent vector before the Dense layer. For the discriminator, a new Dense layer is added. The new layer is used to process the one-hot vector and reshape it so that it is suitable for concatenation to the other input of the...
