Hi,
I have a number of functions for computing raw distance measures and
functions to compute their maxima for a given number of items, so to
normalize them to [0,1] I provide this:
(define (normalize/distance measure maximum)
(lambda (p q)
(/ (measure p q) (maximum (full-domain-size p q)))))
However, the maximum procedure seems unnecessary, because every measure
has its own maximum. So I was wondering whether I could leave it out
and instead use something like this:
(define (get-maximum measure)
(cond
((eq? measure footrule) footrule-maximum)
((eq? measure bogart) bogart-maximum)
.
.
.
(else (error 'get-maximum "unknown measure ~s" measure))))
both internally and for export. But if I also export it, because
sometimes people might want to use the respective procedure directly,
is this really safe? Will this always work, or can this somehow
interfere with macros, modules, etc.?
Best,
Erich
