We developed a new memory relaxation model using a generalized Coulomb potential. This model offers large storage capacity and stable memory states, outperforming the Hopfield model.

Area of Science:

  • Computational neuroscience
  • Artificial intelligence
  • Statistical mechanics

Background:

  • Artificial neural networks are crucial for memory modeling.
  • Existing models like the Hopfield network have limitations in storage capacity and stability.
  • Developing robust memory models is essential for advancing AI and neuroscience.

Purpose of the Study:

  • To introduce a novel relaxation model for associative memory.
  • To demonstrate the model's enhanced storage capacity and stability.
  • To compare the proposed model against the established Hopfield relaxation model.

Main Methods:

  • A relaxation model based on a generalized Coulomb potential was formulated.
  • The model's storage capacity and basin stability were analyzed theoretically.
