This study introduces a novel penalty function for pruning feedforward neural networks, effectively reducing unnecessary connections and preventing large weights. The method achieved sparser networks on benchmark problems compared to existing techniques.

Area of Science:

  • Artificial Intelligence
  • Machine Learning
  • Neural Networks

Background:

  • Feedforward neural networks often contain redundant connections.
  • Network pruning is crucial for improving efficiency and generalization.
  • Existing weight elimination methods may not be optimal.

Purpose of the Study:

  • To propose a new penalty function for effective neural network pruning.
  • To reduce unnecessary connections and control weight magnitudes.
  • To enhance the efficiency of feedforward neural networks.

Main Methods:

  • Developed a two-term penalty function for weight elimination.
  • Incorporated criteria for identifying and removing weights.
  • Applied the pruning method to benchmark datasets.
