Area of Science:

  • Computational Neuroscience
  • Artificial Intelligence
  • Cognitive Science

Background:

  • Neural networks are widely used for pattern recognition and memory coding.
  • Perception involves chaotic, non-linear neural dynamics and oscillations.
  • Existing auto-associative networks offer static pattern association.

Purpose of the Study:

  • To propose an innovative chaotic neural oscillator, the Lee-oscillator.
  • To develop a chaotic auto-associative network, the Lee-Associator.
  • To introduce a Progressive Memory Recalling Scheme (PMRS).

Main Methods:

  • Construction of the Lee-Associator using Lee-oscillators.
  • Demonstration of pattern association capabilities.
  • Comparison with classical auto-associators like the Hopfield network.

Main Results:

  • The Lee-Associator exhibits a Progressive Memory Recalling Scheme (PMRS).
  • PMRS allows for dynamic memory association, unlike static methods.
  • This aligns with research on dynamic memory recall and human perception.

Conclusions:

  • The Lee-oscillator offers a new chaotic neural coding and information processing scheme.
  • The Lee-Associator provides a dynamic approach to memory association.
  • The findings are consistent with psychological studies on perception and memory.
