From: Adapting machine-learning algorithms to design gene circuits
Using GeneNet to learn gene circuits. a A French-Flag circuit responds to intermediate levels of input to generate a stripe. The red node corresponds to the output gene, and the blue node the input. b A “duration-detector” which is irreversibly activated when stimulated by pulses exceeding a certain critical duration. As above, the red node corresponds to the output gene, and the blue node the input. c An oscillator
