This version adds the minSimilarity parameter, which is the primary factor for including/excluding other users from the target user's neighbourhood. Additionally, the 'n' parameter was renamed to maxHoodSize and is used to optionally limit the size of the neighbourhood. > The patch is for a brand new class, but we may really want just a single class (either keep this one and axe NearestNUserNeighborhood or add this functionality to NearestNUserNeighborhood), if this sounds good. > I'll update the unit test and provide a patch for that if others think this can go in. > Thoughts? -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
