The GACluster open source library implements popular Graph Agglomerative Clustering algorithms.

GACluster is distributed under the BSD license (see the COPYING file).

Two major limits of previous GAC toolbox are 1) memory cost and 2) C++ MEX implementation. This new version only includes pure MATLAB code and is optimized for memory. E.g., [5] did not report the result of GDL [1] on 70000 samples of MNIST full dataset due to huge memory cost, and it is possible to run GDL with this library if you have 24G memory. Further optimization is possbile with less readability.

Please cite the following papers, if you find the code is helpful.

GDL without deep representation achieves close performance to state-of-the-art deep clustering algorithms.

Clustering performances of different algorithms in terms of NMI/ACC.

GACluster provides a number of demos for reproducing results on popular datasets.
