add extra plane in the layer

[Alex Ter-Sarkisov]

For fine-tuning: 

There exists a layer (e.g. Deconvolutional) with dimensions (21, 400, 800), and I want to add an extra plane in it, i.e. make it (22,400,800) and fine-tune only this new plane, do I have write a new caffe class for this?

Without knowing what exactly do you want to do, I would suggest creating another Deconvolution layer with (1, 400, 800) output and stacking it with the existing one using Concat layer, then setting lr_mult on the existing deconv to zero.
