Thought this would be relevant to the ongoing Imagenet training project–Google just achieved a new mark of 7:28:30 for training time on Imagenet, beating their own previous record by 5 hours. (https://dawn.cs.stanford.edu/benchmark/#imagenet-train-time).
They were able to do so using an AmoebaNet architecture, which was developing using evolutionary search as described in this paper: https://arxiv.org/abs/1802.01548
