Nancy: Kosslyn subject who had prosopagnosia and who couldn�t see/represent curves
alphabet/number systems that don�t have curves?
he says that he�s now demoting Critic-Selector model�
why do you need alarms as well as critics???
he says:
alarms go off even though nothing triggered them
the critic has to be reacting to something
I don�t get that distinction
does it make sense to think in terms of alarms (because it�s clear that the brain doesn�t have a main loop like a GUI OS)???
Alan Boyd � fourier analysis of teeth growth rates, showed weekly peaks
Sibelius stopped listening to other composers� music � Herbert Spencer, mental hygiene
how specific are cryptamnesic recreations???
Licklider???
could it be that the reason we�re crap at maths is because it�s all about instantiating variables, which NNs are bad at???
what about language?
pronouns, father/mother etc.
well, maths + number is much more cultural than language, which we have some genetic predisposition for, right (creoles etc.)???
maths is bottom-up � you can�t link it into your common sense or semantic knowledge to predict top-down what a sentence is going to mean???
could it be that you can�t spread the mathematical sentence over your 7 memory slots (because it�s all using the same operations), whereas different subordinate clauses can perhaps be chunked in parallel
someone else: there�s more redundancy and it�s less fragile to mistakes
no non-literary society has invented maths
why do mathematicians prefer short variables, vs programmers???
Minsky likes the idea of meta-education � teaching useful learning skills
e.g. the Cicero method of learning lists
Hofstadter discovered a 9-point circle � what�s that???
refce: Geometers� Sketchpad??? � make a bicycle
refce: Jared Lanier � graphical programming language, apparently???
why separate critics and selectors???
how are new critics generated???
didn�t really answer � says it�s just like creating any other resource
but I�m not really clear how the SoM creates resources full stop
punishment assignment � when you fail � punish the critic that led to the failure
Soar chunked the failures
don�t reward an animal for getting something right � it�s already doing it, and you�ll overstrengthen the connection
same with competitive perceptron learning
in RL nets, isn�t the learning rate much higher when it gets it right???
why is language serial???
