详细说明： # DDC-transfer-learning A simple implementation of Deep Domain Confusion: Maximizing for Domain Invariance which is inspired by [transferlearning][https://github.com/jindongwang/transferlearning]. The project contains *Pytorch* code for fine-tuning *Alexnet* as well as *DDCnet* implemented according to the original paper which adds an adaptation layer into the Alexnet. The *office31* dataset used in the paper is also used in this implementation to test the performance of fine-tuning *Alexnet* and *DDCnet* with additional line ar *MMD* loss. # Run the work * Run command `python alextnet_finetune.py` to fine-tune a pretrained *Alexnet* on *office31* dataset with *full-training*. * Run command `python DDC.py` to fine-tune a pretrained *Alexnet* on *office31* dataset with *full-training*. # Experiment Results Here we have to note that *full-training* protocol, which is taking all the samples from one domain as the source or target domain, and *dowm-sample* protocol, which is choosing 20 or 8 samples per category to use as the domain data, are quite different data preparation methods with different experiment results. | Methods | Results (amazon to webcame) | | :------: | :------: | | fine-tuning Alexnet (full-training) in *Pytorch* | Around 51% | | DDC ( pretrained Alexnet with adaptation layer and MMD loss) in *Pytorch* | Around 56% | # Future work - [ ] Write data loader using *down-sample* protocol mentioned in the paper instead of using *full-training* protocol. - [ ] Considering trying a tensorflow version to see if frameworks can have a difference on final experiment results. # Reference Tzeng E, Hoffman J, Zhang N, et al.
