@iNLyze I don't think we need to align images together at all. in fact one of the recommendations was to augment the input data with some rotation and translation so that the model gets more robust. The orientation should be a property of the latent Z vector.
Thanks for the face2face demo link. I just typed about doing that, albeit in reverse.... in the previous post. @brendan @xinxin.li.seattle... check face2face out.
Reg Tensorboard: this particular project uses tensorflow, so I didn't have to do anything. However, I was able to use tensorboard to visualize embedding. It was very very useful for me on that front. You need to deal with some vodoo magic to name the layers and create a mapping via metadata file. I think I posted it on the forum before, IIRC. I can help you with that if you are having issues with that part. Trying to visualize the graph is a mess via tensorboard for me.
