Soonhwan-Kwon opened a new pull request #8787: add CapsNet example
URL: https://github.com/apache/incubator-mxnet/pull/8787
 
 
   ## Description ##
   This example is MXNet implementation of [CapsNet](https://arxiv.org/abs/1710.09829):  
   Sara Sabour, Nicholas Frosst, Geoffrey E Hinton. Dynamic Routing Between Capsules. NIPS 2017
   
   We achieved `the best test error rate=0.29%` and `average test error=0.303%`. It is the best accuracy and fastest training time result among other implementations(Keras, Tensorflow at 2017-11-23).
   The result on paper is `0.25% (average test error rate)`.
   
   | Implementation| test err(%) | ?train time/epoch | GPU  Used|
   | :---: | :---: | :---: |:---: |
   | MXNet | 0.29 | 36 sec | 2 GTX 1080 |
   | tensorflow | 0.49 | ? 10 min | Unknown(4GB Memory) |
   | Keras | 0.30 | 55 sec | 2 GTX 1080 Ti |
   
   ? tensorflow implementation's batch size is not 100 but 128 but MXNet and Keras implementation 's batchsize are 100.
