This is the code of ULDF. Paper of this code is: Yang Wang, Xinggang Wang, Wenyu Liu. Unsupervised Local Deep Feature for Image Recognition

Required libraries (included in the package):

1. VLFeat, by Andrea Vedaldi et al.
2. LibLinear, by Machine Learning Group at National Taiwan University.

How to make it work:

1. Download this code.

2. Download from http://yann.lecun.com/exdb/mnist the following 4 files:

• train-images-idx3-ubyte.gz
• train-labels-idx1-ubyte.gz
• t10k-images-idx3-ubyte.gz
• t10k-labels-idx1-ubyte.gz

3. Unzip these 4 files by executing:

• gunzip train-images-idx3-ubyte.gz
• gunzip train-labels-idx1-ubyte.gz
• gunzip t10k-images-idx3-ubyte.gz
• gunzip t10k-labels-idx1-ubyte.gz

If unzipping with WinZip, make sure the file names have not been changed by Winzip.

4. Run mnistdeepauto.m in matlab. For any question, please contact: Yang Wang (yang-wang16@mails.tsinghua.edu.cn)
