Analysis of Reservoir Computing Using Oscillator Circuit

This paper presents an investigation into networked reservoir computing using interconnected oscillators. Specifically, the Bonhoeffer-van der Pol (BVP) oscillator is used as the basis for the reservoir, and its performance is evaluated in speech recognition tasks. The results reveal that the BVP reservoir exhibits enhanced fidelity to input waveforms and improved accuracy in speech recognition compared to the van der Pol (VDP) reservoir. Furthermore, the impact of reservoir configuration on accuracy is examined by varying the number of oscillators, the connection probability, and the coupling strength. The results indicate that accuracy improves as the parameters are increased. These results emphasize the importance of carefully selecting and setting the dynamics of the physical system and parameters of the reservoir to achieve optimal performance.
