| | What it is | A model is a "cartoon" of a phenomenon -- an information structure that captures the most important (preferably all the important) aspects of a phenomenon in question. | | | What it is | A model is a "cartoon" of a phenomenon -- an information structure that captures the most important (preferably all the important) aspects of a phenomenon in question. | |

| | Science vs. Mathematics | Mathematics is **axiomatic**: Some a-priori premises are (and must be) assumed. \\ Science is non-axiomatic: We do not know the full set of rules that govern the universe, and we will never know. | | | Science vs. Mathematics | Mathematics is **axiomatic**: Some a-priori premises are (and must be) assumed. \\ Science is non-axiomatic: We do not know the full set of rules that govern the universe, and we will never know (for sure). | |
| | Science vs. Engineering | In science we look for the model; \\ in engineering we mold the world to behave like our model. \\ \\ // Example for science: // \\ [phenomenon] // We see something interesting and call it "**intelligence**". // \\ [model] // We come up with theories for how it works. // \\ [empirical research] // We test the models through systematic creation and evaluation of hypotheses. // \\ [create new models] // We revise the theory. // \\ \\ // Example for engineering:// \\ [model] // We have a theory of intelligence. // \\ [engineering] // We want to build an intelligent system. // \\ [implementation] // We use the theory as a blueprint. // \\ [requirements and theory] // We make sure it behaves to its specifications. // | | | Science vs. Engineering | In science we look for the model; \\ in engineering we mold the world to behave like our model. \\ \\ // Example for science: // \\ [phenomenon] // We see something interesting and call it "**intelligence**". // \\ [model] // We come up with theories for how it works. // \\ [empirical research] // We test the models through systematic creation and evaluation of hypotheses. // \\ [create new models] // We revise the theory. // \\ \\ // Example for engineering:// \\ [model] // We have a theory of intelligence. // \\ [engineering] // We want to build an intelligent system. // \\ [implementation] // We use the theory as a blueprint. // \\ [requirements and theory] // We make sure it behaves to its specifications. // | |
| | Why AI is special | Most research fields rely primarily on either the scientific research approach or the engineering approach. \\ //**AI is special in that it is committed to doing both.**// \\ (Although it does not always operate accordingly.) \\ AI is also the only field of science explicitly committed to the phenomenon of intelligence. | | | Why AI is special | Most research fields rely primarily on either the scientific research approach or the engineering approach. \\ //**AI is special in that it is committed to doing both.**// \\ (Although it does not always operate accordingly.) \\ AI is also the only field of science explicitly committed to the phenomenon of intelligence. | |
