Problem: Too much data is being stored due to advanced technology, but we cannot find useful knowledge from it easily.
Solution:No, not all discovered patterns in data mining are interesting. Some are only interesting if they are easy to understand, reliable on new data, potentially useful, or support a hypothesis. It depends on how valuable they are to the user.
No, a data mining system cannot always find all and only interesting patterns. While it aims to find as many interesting patterns as possible, achieving completeness can be challenging. User-provided constraints and measures help focus the search, but generating only interesting patterns efficiently remains a difficult task.
