Multiple short-term memories in coupled weakly nonlinear map lattices

Area of Science:

• Complex Systems
• Nonlinear Dynamics
• Information Theory

Background:

• Coupled map lattices (CMLs) are dynamical systems used to model complex phenomena.
• Investigating memory storage in CMLs is crucial for understanding information processing in such systems.
• Periodic external inputs can significantly alter the behavior of CMLs.

Purpose of the Study:

• To investigate short-time memory storage in coupled map lattices with periodic external forcing.
• To determine the transient lengths required for permanent memory in linear coupled maps.
• To demonstrate the potential of weakly nonlinear coupled maps for encoding information.

Main Methods:

• Successful encoding of symbols into a pixel matrix was achieved.

Conclusions:

• Weakly nonlinear coupled map lattices offer a promising framework for short-time memory storage.
• The ability to store multiple memories can be leveraged for practical data encoding.
• Further research into control laws can optimize information processing in CMLs.
