When Bias Meets Trainability: Connecting Theories of Initialization
arXiv – CS AI|Alberto Bassi, Marco Baity-Jesi, Aurelien Lucchi, Carlo Albert, Emanuele Francazi||4 views
🤖AI Summary
New research connects initial guessing bias in untrained deep neural networks to established mean field theories, proving that optimal initialization for learning requires systematic bias toward specific classes rather than neutral initialization. The study demonstrates that efficient training is fundamentally linked to architectural prejudices present before data exposure.
Key Takeaways
- →Researchers proved that initial guessing bias in untrained neural networks is connected to mean field theories of initialization.
- →Efficient learning in deep neural networks requires systematic bias toward specific classes rather than neutral initialization.
- →The statistical properties of neural network parameters at initialization strongly influence gradient behavior and training success.
- →Untrained networks naturally assign large input regions to single classes, creating inherent architectural biases.
- →Counterintuitively, biased initialization optimizes trainability more effectively than neutral approaches.
