Hc. Peng et al., COMBINING ADAPTIVE SIGMOID PACKET AND TRACE NEURAL-NETWORK FOR FAST INVARIANCE-LEARNING, Electronics Letters, 34(9), 1998, pp. 898-900
By replacing the commonly used sigmoid neuron activation function with
an adaptive sigmoid packet, the invariance extraction of a trace neur
al network can be effectively enhanced and speeded up for fast varying
sample sequences. The performance is compared with several existing m
odels.
