--------------------------------------
Summary: Matrices.symmetricUniformView(...) returning values in
the wrong range.
Key: MAHOUT-1841
URL: https://issues.apache.org/jira/browse/MAHOUT-1841
Project: Mahout
Issue Type: Bug
Components: Math
Affects Versions: 0.12.0
Reporter: Andrew Palumbo
Fix For: 0.12.1
Per javadocs, {{Matrices.symmetricUniformView(...)}} is meant to return values
in on the range of [-1,1):
{code}
/**
* Matrix view based on uniform [-1,1) distribution.
*
* @param seed generator seed
*/
public static final Matrix symmetricUniformView(final int rows,
final int columns,
int seed) {
return functionalMatrixView(rows, columns, uniformSymmetricGenerator(seed),
true);
}
{code}
Ranges being returned now are on (-.5,.5).
