Creativity: “the capacity to create a solution that is both novel and appropriate”.
Creative brains are:
well trained in a given domain, have great imagination, combine faster basic primitives, recognize interesting combinations of these primitives through emotional and associative filtering.
Computational creativityComputational creativityTo understand creative use of words go to the lower level …
construct words from combinations of phonemes, pay attention to morphemes, flexion etc.
Creativity = space + imagination (fluctuations) + filtering (competition)
Space: neural tissue providing space for infinite # of activation patterns. Imagination: many chains of phonemes activate in parallel both words and non-words reps, depending on the strength of synaptic connections. Filtering: associations, emotions, phonological/semantic density.
General ideaGeneral idea
Start from keywords priming phonological representations in the auditory cortex; spread the activation to concepts that are strongly related.
Use inhibition in the winner-takes-most to avoid false associations.
Find fragments that are highly probable, estimate phonological probability.
Combine them, search for good morphemes, estimate semantic probability.
