Chaos and rigorous verification of horseshoes in a class of Hopfield neural networks

Abstract: In this paper, chaos in a new class of threedimensional continuous time Hopfield neural networks is investigated. Numerical experiments show that this class of Hopfield neural networks can have chaotic attractors and limit cycles for different parameter configurations. By virtue of horseshoes theory in dynamic systems, rigorous computerassisted verifications are done for their chaotic behavior. In terms of topological entropy, quantitative interpretations of these neural networks' complexity are given. A brief… Show more

“…The studies carried out on AHNNs have the advantage that they would allow an understanding of a certain number of pathologies affecting memory function and provide a starting point for their resolution. As a result, dynamic behaviors such as chaos [1][2][3], hyperchaos [4][5][6], multistability [7][8][9], and hidden attractors [4,5] have piqued the interest of researchers.…”

“…To facilitate theoretical analysis and experimental implementation, many small HNNs have been intensively studied [1,3,5,[17][18][19][20][21][22]. Complex dynamic behaviors such as periodic, chaotic, or coexisting attractors, crisis scenarios [1,3,5,[17][18][19][20]22], hyperchaos [5,6], relaxation oscillations [21], and hidden attractors [5], to name a few, have generally been revealed in these small HNNs.…”

“…Being another important type of solution, many parallel-processing computational schemes, including various dynamic recurrent neural networks (RNN) solvers, have been developed, analyzed, and implemented on specific architectures [9][10][11][12][13]. The RNN (or termed neural dynamics) approach is now regarded as a powerful alternative to online computation because of its parallel distributed nature and, more importantly, the suitability of hardware realization [11][12][13][14][15][16].…”
