About: Somoclu is a cluster-oriented implementation of self-organizing maps. It relies on MPI for distributing the workload, and it can be accelerated by CUDA on a GPU cluster. A sparse kernel is also included, which is useful for training maps on vector spaces generated in text mining processes.Changes:
Toroid maps were added. Initial radius is exposed as a parameter via the command line interface. Formats of codebook and U-matrix export are compatible with Databionic ESOM Tools for advanced visualisation. Bug fixes: codebook update with a compact support was removed, NaN entry no longer appears in U-matrices.
