https://youtube/watch?v=n8m7lFQ3njk Creativity by using Analogy: One strong evidence that motivates AI experts to make one day creative machines is the Moore’s law which dictates that electronics hardware is getting cheaper and reducing in surface exponentially which allows for mass computation as replacement of burst of energy getting released during the insight. All insights are subliminal computations of mind or brain which appears in one flash as insight. No leap happens in thinking during insight is the key principal predicted in Marvin Minsky’s 1985 book Society of Mind, which allows capturing insight by massive computation. Douglas Hofstadter, Professor Cognitive Science, Indiana University suggests a different hypothesis to capture minimal creativity by Machines through Analogy. He has given a hypothesis called core cognitive hypothesis which asserts that all creativity is making analogy by cognition. In fact the thought of Douglas Hofstadter is not new since a variant of this thought was used by an Expert system Dendral used to identify the molecular structure made by Ed Feigenbaum which employed the thought that we solve problems often by making similarity with the similar nature problem solved previously. Hofstadter lab has developed few types of software using this hypothesis and one of them is Copycat. When Copycat is given a sequence like “abc”, and “ijk”, and abc is changed to “abd”, software uses analogy to understand that “ïjk”, is to be replaced by “ïjl”. Copycat understands analogy of more complicate nature due to certain creative observations in making analogy. Seeing the naivety of the Copycat, Douglas Hofstadter, is quite suspicious of Singularity movement of Ray Kurzweil, Director Engineering Google, prophesizing that by 2040, Machines will be human equivalents in intelligence. Those interested can see this debate in You tube by searching, “Singularity Summit Stanford + Douglas Hofstadter”.
