Detailed Description

template<typename T>
class aureservoir::SimFilterDS< T >

This version works like SimFilter, but has an additional delay&sum readout, which means that not only a single weight but also a delay is learned in the readout. Therefore it can be used to identify systems with long-term dependencies.

See also:

class SimFilter

class IIRFilter

See "Echo State Networks with Filter Neurons and a Delay&Sum Readout" (Georg Holzmann, 2008).
