EasyTL: Practically Easy Transfer Learning

This directory contains the code for paper Easy Transfer Learning By Exploiting Intra-domain Structures published at IEEE International Conference on Multimedia & Expo (ICME) 2019.


The original code is written using Matlab R2017a. I think all versions after 2015 can run the code.

The Python version is on the way.

Demo & Usage

I offer three basic demos to reproduce the experiments in this paper:

  • For Amazon Review dataset, please run demo_amazon_review.m.
  • For Office-Caltech dataset, please run demo_office_caltech.m.
  • For ImageCLEF-DA and Office-Home datasets, please run demo_image.m.

Note that this directory does not contains any dataset. You can download them at the following links, and then add the folder to your Matlab path before running the code.

Download Amazon Review dataset with extraction code a82t.

Download Office-Caltech with SURF features

Download Image-CLEF ResNet-50 pretrained features

Download Office-Home ResNet-50 pretrained features

You are welcome to run EasyTL on other public datasets such as here. You can also use your own datasets.

EasyTL achieved state-of-the-art performances compared to a lot of traditional and deep methods as of March 2019:

You can’t perform that action at this time.
