Universal Java Matrix Package
· The Universal Java Matrix Package (UJMP) is an open source library for dense and sparse matrix computations and
linear algebra in Java. In addition to the basic operations like matrix multiplication, matrix inverse or
decomposition methods, it also supports visualization, JDBC import/export and many other useful functions such
as mean, correlation, standard deviation, mutual information, or the replacement of missing values.
It's a swiss army knife for data processing in Java, tailored to machine learning applications.
