Influence of Time Delay on Bifurcation in Fractional Order BAM Neural Networks With Four Delays

Abstract: Over the past several decades, numerous scholars have studied the stability and Hopf bifurcation problem of integer-order delayed neural networks. However, the fruits about the stability and Hopf bifurcation for fractional-order delayed neural networks are very scarce. In this paper, we will consider the stability and the existence of Hopf bifurcation of fractional-order bidirectional associative memory (BAM) neural networks with four delays. A set of sufficient criteria to ensure the stability and the existen… Show more

“…As the rest of the paper depends on A 1 (s) and A 2 (s), which rely on the values of a i for i = 1, 2, 3, 4, 5, special attention should be given to these values. For this purpose, the correct value of a 1 = α 1 + α 2 + α 3 should be used in equation ( 7) in [1], which should be followed in the rest of paper [1].…”

“…In many artificial neural network models, there is an important two-layer heterogeneous associative network called Bidirectional Associative Memory (BAM) neural network with axon signal transmission delay. Since BAM neural network has potential applications in many fields such as signal processing, pattern recognition and optimization problems [13], it has always been one of the most active areas of research and has attracted many attention of many researchers [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. In recent decades, many papers have discussed and studied the BAM neural network, which were first reported by Kosko [14,15].…”
