Andrew Palumbo updated MAHOUT-1884: ----------------------------------- Fix Version/s: (was: 0.13.0) 0.13.1 > Allow specification of dimensions of a DRM > ------------------------------------------ > > Key: MAHOUT-1884 > URL: https://issues.apache.org/jira/browse/MAHOUT-1884 > Project: Mahout > Issue Type: Improvement > Affects Versions: 0.12.2 > Reporter: Sebastian Schelter > Assignee: Andrew Palumbo > Priority: Minor > Fix For: 0.13.1 > > > Currently, in many cases, a DRM must be read to compute its dimensions when a > user calls nrow or ncol. This also implicitly caches the corresponding DRM. > In some cases, the user actually knows the matrix dimensions (e.g., when the > matrices are synthetically generated, or when some metadata about them is > known). In such cases, the user should be able to specify the dimensions upon > creating the DRM and the caching should be avoided. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
