Summary

• What is new: Introduces a self-expanding neural network approach that dynamically adjusts its architecture—both width and depth—during training to potentially reduce converged training loss.
• Why this is important: Choosing the right neural network architecture is crucial for its performance, but even slight modifications require restarting the training process.
• What the research proposes: A natural gradient based approach that expands the neural network’s architecture as needed, without disrupting prior optimizations and with bounds on the expansion rate.
• Results: Demonstrated benefits in classification and regression problems, showing effectiveness in scenarios where the optimal architecture size is not known in advance.
