[ENHANCEMENT] Semantics of option "max. characters" in masking-based hierarchy wizard is unclear

Open idhamari opened this issue 2 years ago • 2 comments

Describe the bug When one changes the number in the Max character it has no effect.

ArxBugMasking

To Reproduce Steps to reproduce the behavior:

  1. Go to 'Edit>Create Hierarchy...'
  2. Click on 'Use Masking ...'
  3. Change the number in Max. hierarchy e.g. 1
  4. The result is the same when selecting a larger number e.g. 5!!!

Expected behavior Should mask only one character when Max. Characters is 1

ARX GUI (please complete the following information):

  • OS: Windows 10
  • Version 3.9.0 and 3.9.1

The "max. characters" attribute, and other domain properties, are only used in the Loss metric calculations. They do not change the generalization method (same in the API). I think if the above behavior is needed, an additional attribute will be required.

This is not a bug. The semantics of the field is just confusing. It will not influence how masking is applied to individual values but will have an influence on how information loss / utility is measured when functional hierarchies are being used.
