Maintenance prediction is something we worked on. Here a related application that has many possibilities. How about very rare breakdown occurences? In IEEE Spectrum:
Deep Learning AI Listens to Machines For Signs of Trouble By Jeremy Hsu
" .... The service of 3DSignals, a startup based in Kefar Sava, Israel, relies on the artificial intelligence technique known as deep learning to understand the noise patterns of troubled machines and predict problems in advance. 3DSignals has already begun talking with leading European automakers about possibly using the deep learning service to detect possible trouble both in auto factory machinery and in the cars themselves. The startup has even chatted with companies about using their service to automatically detect problems in future taxi fleets of driverless cars. .... "
