About: A Python library that allows you to define, optimize, and evaluate mathematical expressions involving multi-dimensional arrays efficiently. Dynamically generates CPU and GPU modules for good performance. Deep Learning Tutorials illustrate deep learning with Theano.Changes:
Theano 0.6 (December 3th, 2013)
0.6rc4 skipped for a technical reason.
Highlights (since 0.6rc3):
Too much changes in 0.6rc1, 0.6rc2 and 0.6rc3 to list here. See https://github.com/Theano/Theano/blob/master/NEWS.txt for details.
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.
