Data Science Asked by lppier on June 5, 2021
I’m currently a student doing some machine learning projects, and I want to use generative adversarial networks to train some data to discern for example, how old someone is. The intended output is a regression continuous output in term of months.
I see the DCGANs and GANs are targeting mainly classification problems. Can they be used to solve regression problems?
Thank you.
The answer is yes. There is a paper Intra-class Variation Isolation in Conditional GANs (https://arxiv.org/pdf/1811.11296.pdf) discussing it.
They propose a "C-GAN that is able to learn realistic models with continuous, semantically meaningful input parameters". They actually cover generating images of people at different ages as well.

I am also interesting about it. Recently, I found a paper which the authors used a conditional GAN for regression tasks, in hope it will drive you over this problem. For a detail about this paper, see here.

It is possible to train a Convolutional regression model, and train it adversarially. So in theory you can. @Zhongsheng Chen linked a case of a Conditional GAN used for regression, even though I didn't find DCGANs for this, specifically.
In other words: it is possible in theory, but in practice using very large and heavy models such as GANs to run a regression is a like killing moquitoes with a bazooka.
