Similarity Transformation Matrix
write_matrix_bin(f,m) saves the matrix "m" in a binaryfile "f". write_matrix_bin is a lot faster than the built in function save(), andtakes up much less diskspace than the old "save -v6" which doesn't use compression.write_matrix_bin also includes an option for compression with...

This is a learning model for matrix-based data. It can be more efficient than standard vector-based models when the training sample is small or the inputs are matrices, since this model has less parameters than standard ones and exploits an inner structure of the inputs. This model can be...
