"copycat": "copycat", on behalf of those Zhanshanweiwang site, has not officially under the jurisdiction of the means. "copycat" is to rely on copying, imitation, spoof and other means to grow up, anti-authority, anti-mainstream, and with the revelry, deconstructive, and post-modern anti-intellectual subculture characterized by mass culture. As a new culture, follow the trend of never less to be proud of the copycat, copycat behavior in a class of people, began to gather together people claiming to copycat, and copycat copycat products were produced naturally as knockoff. Today knockoff began strange refers to those peculiar commodity.
How Minds Work The Copycat Architecture Stan Franklin Computer Science Division & Institute for Intelligent Systems The University of Memphis 1 Copycat Architecture • Hilevel perception • Analogy making • Creative • Parts—Slipnet, workspace, codelets • No central executive • Decisions made by codelets HMW: Pandemonium Theory 2 Alphabetical Analogies • abc —> abd ijk —> ? • abc —> abd xyz —> ? • abc —> abd iijjkk —> ? • abc —> abd srqp —> ? HMW: Pandemonium Theory 3 Slipnet • Directed graph of nodes, representing concepts, and labeled links • Links represent relations between nodes • Nodes support activation, links pass it • Slipnet does not learn • Nodes don’t decay, but activation does • Slipnet is longterm memory HMW: Pandemonium Theory 4 Slipnet at Work • Relevant nodes activated by codelets • Nodes spread activation to neighbors over links, starting with nearest • Concepts close to relevant concepts become relevant • Slipnet settles, activation pattern becomes stable HMW: Pandemonium Theory 5 Fluid Concepts • Region of the Slipnet • Concept node at the core (center) • Neighboring nodes included stochastically by context dependent similarity • Fluid concepts vary over time, are emergent, and aren’t explicitly represented HMW: Pandemonium Theory 6 Workspace • Codelets build perceptual structures using information from the Slipnet • Information—nodes, links, labels • Structure represents Copycat’s current appraisal of the situation HMW: Pandemonium Theory 7 Interactive Problem Solving • Bottomup workspace influence activates relevant Slipnet nodes • Spreading activation identifies other relevant nodes • Topdown Slipnet influence activates relevant codelets who change the workspace • Eventually, some codelet decides to stop HMW: Pandemonium Theory 8 Temperature Control • High temperature = more randomness in choices of codelets & their actions • Low temperature = more stability • Temperature inversely measures system’s understanding of the situation • Temperature controlled, parallel terraced scan • Example run in Artificial Minds HMW: Pandemonium Theory 9 Readings Copycat Architecture • Hofstadter, D.
