Feedback GAN for DNA optimizes protein functions

Generative adversarial networks (GANs) represent an attractive and novel approach to generate realistic data, such as genes, proteins or drugs, in synthetic biology. Here, we apply GANs to generate synthetic DNA sequences encoding for proteins of variable length. We propose a novel feedback-loop architecture, feedback GAN (FBGAN), to optimize the synthetic gene sequences for desired properties using an external function analyser. The proposed...
