Classification problem solving itself can be viewed as having a control component whi ch selects hyp ot heses to consider, and a decision component associated with each selected hypothe sis. In this paper we st udy the family of control regimes that are useful in classificatory problem solving. We start with MDX, a cla ssification system organized as a hierar chical collection of hyp ot hesis specialists, critique it s control behavior , and by considering a set of sit ua tions involving multiple di seases, show how elements can be added to the cont rol regime in a modular way to handle a large variety of s ituati ons.","doi":null,"url":"https://ijcai.org/proceedings/1985/57","pdf":"https://ijcai.org/proceedings/1985/0057.pdf","markdown":"https://ijcai.org/proceedings/1985/57.md","bibtex":"https://ijcai.org/proceedings/1985/bibtex/57","volume":{"slug":"1985","title":"Proceedings of the Ninth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1985","url":"https://ijcai.org/proceedings/1985/","year":1985,"location":"Los Angeles, California, USA","dates":"","editors":"Aravind Joshi","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Expert Systems","track":"Expert Systems","number":57,"pages":{"first":300,"last":305},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
