TY - JOUR T1 - Echo state networks with multiple readout modules JF - bioRxiv DO - 10.1101/017558 SP - 017558 A2 - , Y1 - 2015/01/01 UR - http://biorxiv.org/content/early/2015/06/07/017558.abstract N2 - We propose a new readout architecture for echo state networks where multiple linear readout modules are activated at distinct time points to varying degrees by a separate controller module. The controller module, like the reservoir of the echo state network, can be initialized randomly. All linear readout modules are trained through simple linear regression, which is the only adaptive step in the modified algorithm. The resulting architecture provides modest improvements on a variety of time series processing tasks (between 5 to 50% in performance metric depending on the task studied). The novel architecture is guaranteed to perform at least as accurately as a conventional linear readout. It can be utilized as a general purpose readout method when augmentations to performance relative to the standard method is needed. ER -
