The datasets and source code of Learning-Free Continuous-Attribute Graph Embedding via Locality-Sensitive Hashing.

The steps of running the experiments:

Preparation work

1. compile svmtrain in libsvm-matlab by referring to libsvm-matlab/matlab/README
2. put the mex file in the same directory as 'main.m'
3. cd HashWLS

Graph Classification

run graph_classification.m

Graph Retrieval

run graph_retrieval.m
