Performance of a Stochastic Learning Microchip
Joshua Alspector, Bhusan Gupta, and Robert B. Allen


We have fabricated a test chip in 2 micron CMOS that can  perform
supervised learning in a manner similar to the Boltzmann machine.
Patterns can be presented to it at 100,000 per second.  The  chip
learns  to  solve the XOR problem in a few milliseconds.  We also
have demonstrated the capability to do  unsupervised  competitive
learning with it.  The functions of the chip components are exam-
ined and the performance is assessed.
