Wit:. the relative entropy between the \"ideal attribute\" and \"heuristic attribute\" sets as an index o!' performance, optimum selection of possible heuristic operators results in a recognition decision in probabilitty, with the smallest possible average number of tests during a \"sequential analysis\". On the other hand, a computer generation of q_:;.asi -optimal operators may be done based on n ' ..:r~e rical attributes using the same entropy index of performance. Experimental res:;.! t s are presented : Optimal operator choice is demonstrated for recognition of handwritten capital letter words and for vocoder speech recognition. Cccputer building of quasi-optimal operators is stcwn fer digitized images. They are limited to first level linear pumerical operators.","doi":null,"url":"https://ijcai.org/proceedings/1971/40","pdf":"https://ijcai.org/proceedings/1971/0040.pdf","markdown":"https://ijcai.org/proceedings/1971/40.md","bibtex":"https://ijcai.org/proceedings/1971/bibtex/40","volume":{"slug":"1971","title":"Proceedings of the Second International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1971","url":"https://ijcai.org/proceedings/1971/","year":1971,"location":"London, UK","dates":"","editors":"D.C.
