Should Be easy enough to reproduce. > SequentialAccessSparseVector inerateNonZeros is incorrect. > ---------------------------------------------------------- > > Key: MAHOUT-1882 > URL: https://issues.apache.org/jira/browse/MAHOUT-1882 > Project: Mahout > Issue Type: Bug > Components: Math > Affects Versions: 0.12.2 > Reporter: Andrew Palumbo > Fix For: 0.13.0 > > > In {{SequentialAccessSparseVector}} a bug is noted. When Cuonting Non-Zero > elements {{NonDefaultIterator}} can, under certain circumstances give an > incorrect iterator of size different from the actual non-zeroCounts. > {code} > @Override > public Iterator<Element> iterateNonZero() { > // TODO: this is a bug, since nonDefaultIterator doesn't hold to non-zero > contract. > return new NonDefaultIterator(); > } > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
