Question

Echo State Network - What is the difference between echo state network and liquid state machine?

Answer

Echo State Network (ESN) and Liquid State Machine (LSM) are two algorithms with the primary difference being that LSM is a biologically inspired spiking neural network (SNN), while the ESN is a rate-based approximation. ESN was introduced by Jaeger in 2001 and LSM by Maass et al., in 2002.
