Implement adjustable gradient clipping

modify sgd_solver.cpp in your_caffe_root/src/caffe/solvers/, where we add the following codes in funciton ClipGradients():

Dtype rate = GetLearningRate();

const Dtype clip_gradients = this->param_.clip_gradients()/rate;

Training (Taking Super-resolution task as the example)

1. Preparing training/validation data using the files: generate_trainingset_x234/generate_testingset_x234 in "data/SuperResolution" folder. "Train_291" folder contains 291 training images and "Set5" folder is a popular benchmark dataset.

2. We release two MemNet architectures: MemNet_M6R6_80C64 and MemNet_M10R10_212C64 in "caffe_files" folder. Choose either one to do training.

    $ cd ./caffe_files/MemNet_M6R6_80C64
    $ ./train_MemNet_M6R6_80C64.sh
   

Test (Taking Super-resolution task as the example)

1. Remember to compile the matlab wrapper: make matcaffe, since we use matlab to do testing.

2. We release two pretrained models: MemNet_M6R6_80C64 and MemNet_M10R10_212C64 in "model" folder. Choose either one to do testing on benchmark Set5.

    $ cd ./results/MemNet_M6R6_80C64
    $ matlab
    >> test_MemNet_M6R6_SR
   

   The results are stored in "results" folder, with both reconstructed images and PSNR/SSIMs.
