transfer-caffe

This is a caffe repository for transfer learning. We fork the repository with version ID 29cdee7 from Caffe and make our modifications. The main modifications are listed as follow:

• Add mmd layer described in paper "Learning Transferable Features with Deep Adaptation Networks".
• Add jmmd layer described in paper "Deep Transfer Learning with Joint Adaptation Networks".
• Add entropy layer and outerproduct layer described in paper "Unsupervised Domain Adaptation with Residual Transfer Networks".
• Copy grl layer and messenger.hpp from repository Caffe.
• Emit SOLVER_ITER_CHANGE message in solver.cpp when iter_ changes.

Data Preparation

In data/office/*.txt, we give the lists of three domains in Office dataset.

We have published the Image-Clef dataset we use here.

Training Model

In models/DAN/amazon_to_webcam, we give an example model based on Alexnet to show how to transfer from amazon to webcam. In this model, we insert mmd layers after fc7 and fc8 individually.

The bvlc_reference_caffenet is used as the pre-trained model. If the Office dataset and pre-trained caffemodel are prepared, the example can be run with the following command:

"./build/tools/caffe train -solver models/DAN/amazon_to_webcam/solver.prototxt -weights models/bvlc_reference_caffenet/bvlc_reference_caffenet.caffemodel"

Resnet pre-trainded model is here. We use Resnet-50.

In models/JAN, we give example models based on Alexnet and Resnet to show how to transfer from amazon to webcam, according to "Deep Transfer Learning with Joint Adaptation Networks". The shell scripts to train JAN model are the same with the above command, except that the paths of solver.prototxt and pretrained caffemodel are different.

As JAN uses the joint distribution of features (e.g. fc7) and softmax output (fc8) which are randomized at the beginning of training, one should stablize training by adding grl layer before JMMD Loss Layer to increase the loss weight from zero gradually, as suggested in the train_val.prototxt.

Parameter Tuning

In mmd-layer and jmmd-layer, parameter loss_weight can be tuned to give mmd/jmmd loss different weights.
