Abstract

Liquid State Machines [1] are a new strategie for real-time information processing in recurrent networks. In the present work we show that spatially coupled oscillators can be used as a usable liquid. If inputs stream are synchronized to oscillator phase its temporal dynamics can be be transformed into a high dimensional spatial pattern of oscillator activity. A memory less readout function can extract information about recent inputs. The fading memory is considered as the resynchronisation of oscillator field and can be adjusted by the parameter of small world connection mechanisms.
