Pab<strong>lo</strong> D. Slemenson“Lógica <strong>de</strong> <strong>lo</strong> <strong>preconciente</strong>”f will represent the <strong>de</strong>gree to which a and b are consi<strong>de</strong>red simi<strong>la</strong>r. f is an increasingfunction of the size of AÇB, and a <strong>de</strong>creasing function of the size of A-B and B-A. (2)In metric simi<strong>la</strong>rity, objects are assumed to have features that are <strong>de</strong>scribable in crisp orfuzzy measures (linguistic variables). For instance, a human face has features such aseyes, lips, and nose, each of which may have one or more measures e.g., <strong>lo</strong>ng curved(nose), fat (lips), and <strong>la</strong>rge brown (eyes). Simi<strong>la</strong>rity of objects is <strong>de</strong>fined in terms ofsimi<strong>la</strong>rity of their features. Simi<strong>la</strong>rity of features is <strong>de</strong>fined with respect to simi<strong>la</strong>rity offeature measures. In most applications, one must apply both types of simi<strong>la</strong>rity. Type 1simi<strong>la</strong>rity is applicable in cases where presence or absence of features p<strong>la</strong>y a role. Type2 simi<strong>la</strong>rity is applicable in cases where a feature may have one or more measures andthe measures take on crisp or fuzzy values. The feature measures of an object arecombined to obtain a measure for the object to make <strong>de</strong>cisions as the outcome ofdiagnosis or recognition. The combination method <strong>de</strong>pends heavily on theapplication/user. 1StaffThe Roles of Soft Computing and Fuzzy Logic in the Conception, Design, andUtilization of Information/Intelligent Systems(Professor Lotfi A. Za<strong>de</strong>h)(ARO) DAAH-04-961-0341, Berkeley Initiative on Soft Computing, British Telecom,(LLNL) B-291525, (NASA) NAC2-1177, and (ONR) N00014-96-1-0556Soft computing (SC) is a consortium of methodo<strong>lo</strong>gies that provi<strong>de</strong>s a foundation forthe conception, <strong>de</strong>sign, and <strong>de</strong>p<strong>lo</strong>yment of intelligent systems. The principal membersof SC are fuzzy <strong>lo</strong>gic (FL), neurocomputing (NC), evolutionary computing (EC), andprobabilistic computing (PC), with PC subsuming evi<strong>de</strong>ntial reasoning, management ofuncertainty, and parts of machine learning theory. Within SC, the main contribution ofFL is a methodo<strong>lo</strong>gy for <strong>de</strong>aling with imprecision, approximate reasoning, fuzzyinformation granu<strong>la</strong>tion, and computing with words; that of NC is systemi<strong>de</strong>ntification, learning, and adaptation; that of EC is systematized random research,tuning, and optimization; and that of PC is <strong>de</strong>cision analysis and management ofuncertainty. The essence of soft computing is that unlike the traditional, hardcomputing, soft computing is aimed at an accommodation with the pervasiveimprecision of the real world. Thus, the guiding principle of soft computing is: exp<strong>lo</strong>itthe tolerance for imprecision, uncertainty, and partial truth to achieve tractability,Apendice 317
