The GACluster open source library implements popular Graph Agglomerative Clustering algorithms. GACluster is a better alternative to conventional algorithms, such as k-means, spectral clustering and linkage. GACluster provides strong baselines on popular image clustering datasets, such as MNIST, USPS, Fashion-MNIST.
