Brain-inspired Computer Architecture

Electrical engineering alumnus Dharmendra Modha is working on a brain-inspired computer architecture at IBM. It's part of the SyNAPSE project.

CNET covered the most recent update on this project which is "new software ecosystem was built to program silicon chips whose architecture is directly inspired by the brain's size, function, and minimal use of power."

Keep up with Modha's research on his blog "Dharmendra S Modha's Cognitive Computing Blog".

Check out the 2009 Pulse story celebrating the fact that the IEEE selected Modha as one of seven top minds to discuss how emerging technologies have the potential to change the world.

  1. Not new and not "news"!!! What Hopfield and student Sejnowski never realized nor gave credit for is as follows: Artificial neural-networks(ANN) patterned on biological neural networks(BNN) artificial-intelligence(ANN) were alive and well long before 1980 when physicist Edward Siegel [consulting with Richard Feynman(Caltech) for ANN AI pioneer Charles Rosen(Machine-Intelligence) & Irwin Wunderman(H.P.) & Vesco Marinov & Adolph Smith(Exxon Enterprises/A.I.) discovered trendy much-hyped "quantum-computing" by two-steps: (1) "EUREKA": realization that ANNs by-rote on-node switching sigmoid-function 1/[1 + e^(E/T)] ~ 1/[1 + e^(hw/kT)] ~ 1/[+ 1 + e^(E/T)] ~ 1/[ + 1 + e^(hw/kT)] is Fermi-Dirac quantum-statistics 1/[1 + e^ (E/ T)] ~ 1/[1 + e^(hw/kT)] ~ 1/[+ 1 + e^(E/T)] ~ 1/[ + 1 + e^(hw/kT)] = 1/[e^(hw/kT) + 1] dominated by Pauli exclusion-principle forcing non-optimal local-minima(example: periodic-table's chemical-elements) forcing slow memory-costly computational-complexity Boltzmann-machine plus simulated-annealing, but permitting from non-optimal local-minima to optimal global-minimum quantum-tunneling!!! (2) "SHAZAM": quantum-statistics "supersymmetry"- transmutation from Fermi-Dirac to Bose-Einstein 1/[+ 1/[e^(hw/kT) + 1] ---> 1/[e^(hw/kT) - 1] ~ 1/f power-spectrum, with no local-minima and permitting Bose-Einstein condensation( BEC) via a noise-induced phase-transition (NIT). Frohlich biological BEC & BNN 1/f-"noise"~"generalized-susceptibility" power-spectrum concurred!!! Siegel's work[IBM Conference on Computers & Mathematis,Stanford(1986); Symposium on Fractals, MRS Fall Meeting, Boston(1989)=five seminal-papers!!!] was used without any attribution whatsoever as/by "Page-Brin" PageRank[R. Belew, Finding Out About, Cambridge(2000)]Google first search-engine!!! Siegel empirically rediscovered Aristotle's"square-of-opposition" in physics and mathematics, which three-dimensionally tic-tac-toe diagrams synonyms(functors) versus antonyms (morphisms) versus analogy/metaphor. Amazingly neuroimager Jan Wedeen has recently clinically discovered just such a three-dimensional network of neurons which dominates human brain thinking. Siegel "FUZZYICS=CATEGORYICS=PRAGMATYICS"/ Category-Semantics Cognition for physics/mathematics is a purposely-simple variant of Altshuler-Tsurakov-Lewis "TRIZ"(Russian acronym: "Method of Inventive Problem-Solving") embodied in softwares Invention-Machine(Boston) and Ideation(Michigan)for engineers inventing optimality!
