A scalable pattern-matching architecture utilizing phase oscillators of different frequencies

Oscillatory networks can in principle be used for pattern recognition. However, current architectures either lack scalability towards large numbers of oscillators or they need the external input of complex time-dependent coupling functions. In the architecture we present here, the number of physical connections grows linearly with the number of oscillators and necessary coupling functions are generated in the network itself. The symmetric structure of the architecture and a new type of coupling function guarantee high stability of the matching mechanism up to high coupling strengths.
