Traditional transfer learning

Here we implement several popular traditional transfer learning methods.
Most of the datasets are based on Office-Caltech10 Surf features, which can be downloaded here: https://www.jianguoyun.com/p/DaKoCGIQmN7PCBju9KsD, with password PRSZD9.
We also provide a notebook for you to directly run two algorithms using Jupyter notebook.
You can easily download the notebook from here.
We also put it on Google Colab.
Try and experiment on them!
