Might be kind of overkill. The patterns being looked at for exoplanets are periodical dimming of stars AFAIK. I don't think you necessarily need a neural network to sift through that.

- QAPereo 9y agoThey are also very very far away, and only a few photons are making it to the lens every so often; it's quite a difficult task.

But recently we're starting to actually directly take sensitive enough images to be able to see planets (see http://planetimager.org http://planetimager.org). They aren't using NNs yet. But there have been discussions of using NNs for various aspects of those searches.
