Summary :

An approach is described to synthesis and recognition of temporal patterns by using neural networks. A neural network is trained to produce prescribed waveforms with the steepest descent method which optimizes analog dynamics of neural networks described by differential equations. First a technique is developed for calculating error sensitivities with respect to network parameters by the adjoint network approach. Next an upper bound on timesteps is established to ensure the stability of the numerical solutions of the differential equations of networks. The effectiveness of these techniques are verified by several examples of learning of transient or oscillating waveforms with simple networks. In addition the complexity of the waveform is discussed which can be synthesized by a simple class of neural networks.
