The A* algorithm optimizes Neural Network (NN) structures for better data fitting, avoiding trial-and-error. This method aids in recognizing patterns in epileptic patient EEG data.

Area of Science:

  • Computational Neuroscience
  • Artificial Intelligence
  • Biomedical Engineering

Background:

  • Empirical testing of Neural Network (NN) structures is time-consuming and inefficient.
  • Optimizing NN architecture is crucial for effective data learning and pattern recognition.

Purpose of the Study:

  • To introduce a novel method for automatically constructing optimal Neural Network structures.
  • To apply this method for analyzing electroencephalogram (EEG) data from epileptic patients.

Main Methods:

  • Utilizing the A* search algorithm to determine the best Neural Network structure.
  • Applying the developed method to a dataset of EEG signals from epileptic individuals.

Main Results:

  • The A* algorithm successfully constructed Neural Network structures that optimally fit the data.
