SUMMARY:Invited Talk 3:  The Pursuit of the Brain’s Ubiquitous Stochastici
 ty
DESCRIPTION:Brad Aimone (Sandia National Laboratories)\n\nOne of the most 
 dramatic differences between the brain and modern computing systems is the
  ubiquitous stochasticity of neural circuits.  The brain leverages noise i
 n its biophysics to make its computations more powerful and efficient, whe
 reas today’s computers are designed, at great expense, to be deterministic
  from the transistor up. Such determinism is assumed to be necessary for m
 icroelectronics, but it leads to high costs in both fabrication and in the
  design of probabilistic computing applications.  \n\nIn this talk, I will
  describe how modern neuromorphic computing are approaching this level of 
 widespread stochasticity, enabling the development of a new class of proba
 bilistic neuromorphic applications.  The talk will highlight our results o
 n implementing Monte Carlo random walk applications and stochastic optimiz
 ation on the Intel Loihi, SpiNNaker, and IBM TrueNorth systems, showing ho
 w today’s neuromorphic systems are increasingly competitive with CPUs and 
 GPUs.  Finally, I will describe how future neuromorphic systems that lever
 age true random number generation from stochastic “coinflip” devices may p
 rove critical for realizing the full potential for neuromorphic computing 
 for scientific applications.\n\nTag: Algorithms, Heterogeneous Computing,
