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 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.

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 is 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"

Parameter Tuning

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