Similarly to the question Do we really need the tag ai-basics?, do we really need the tag concepts?
The current description of the tag is
Use for broad questions on the concepts used in AI and implementations. Breakdowns of subfields, methods, and sets of methods, with an emphasis on context and utility.
I think that the description of the tag is unclear and ambiguous, and the tag seems to be superfluous.
First, (too) broad questions are not suited for Stack Exchange websites. Second, we already have the tag theory and implementation. Regarding the part Breakdowns of subfields, methods, and sets of methods, with an emphasis on context and utility., this is really very vague and unclear. Therefore, I suggest the deletion of this tag from the system.
