Title: A statistical mechanics of an oscillator associative memory with
  scattered natural frequencies

Abstract:
  We analyze an oscillator associative memory with scattered natural 
frequencies in memory retrieval states by a statistical mechanical 
method based on the SCSNA and the Sakaguchi-Kuramoto theory. 
The system with infinite stored patterns has a frustration on 
the synaptic weights. In addition, it is numerically shown that 
almost all oscillators synchronize under memory retrieval, 
but desynchronize under spurious memory retrieval, when setting
optimal parameters. Thus, it is possible to determine whether 
the recalling process is successful or not using information 
about the synchrony/asynchrony. The solvable toy model presented 
in this paper may be a good candidate for showing the validity 
of the synchronized population coding in the brain proposed by 
Phillips and Singer.
