Khurrum, mahout is so much a library at this point.
if you mean if it can be used to build networks with 2d inputs, yes i did some of that. multi-epoch SGD based systems should be easy enough to build, and will probably have a reasonable performance -- although I think dedicated CNN systems like Caffe would still run faster at this point. Full batch trainers are somewhat slow for larger problems though, my investigation points that there are architectural problems in spark that are hard to overcome at this point for high IO algorithms.
