- Hello,
-
- I was wondering if anyone knew of any work that has been done on
- learning from subjective data. For instance, you may have a data set
- of events with a number of independent attribute (x1...xn) and a
- single dependent attribute y. However, y is a subjective rating.
-
- For instance, the event could be a work of art and the x's could be
- various nominal/real-valued attribues of the painting. Then paintings
- in the datasets would be given a grade on (say) beauty (the "y"
- attribute) by a number of different "experts" (whose notions of
- good/bad/indifferent obviously vary wildly). Each painting would be
- rated only once by a randomly chosen expert (from an arbitrarily large
- pool of experts -- perhaps even a different expert for every
- painting).
-
- The goal would be to try and learn something useful from this data
- set. I do not mean to apply that something meaningful could be
- learned about art, but surely there would be other application like
- quality control, etc.
-
- Anyway, this seems to be a very interesting problem and I was
- wondering if anyone could give me any pointers to any such work in the
- ML or stats community.
-
- Thanks in advance for any help. Please post to comp.ai or send mail
- to bharat@cs.uiuc.edu and I will summarize and post.
