• Please note this is only a simple demo for the Mnist experiments based on Lenet.
• Please note the algorithm in the demo is little different to the paper, but the main spirit is same.
• The code is based on the Theano framework, which is somehow too old to directly apply this code.

Refer to loss_lenet_light_dynamic.py for the detailed demo codes. The general comments are here:

• Define the loss parameters and loss computation graph
• Teacher model paramters
• Define the updates of model training according to the loss function (jointly train model update)
• Define the reverse mode training
• Train student model with fixed loss function
• Detailed reverse model training

The 'reverse model training' defines the updates of the teacher model, and the last one is the detailed reverse model update chains.
