Align Forward, Adapt Backward: Closing the Discretization Gap in Logic Gate Networks

arXiv – CS AI|Youngsung Kim|
🤖AI Summary

Researchers propose CAGE (Confidence-Adaptive Gradient Estimation) to solve the training-inference mismatch problem in neural networks that use soft mixtures during training but hard selection during inference. The method achieves over 98% accuracy on MNIST with zero selection gap, significantly outperforming existing approaches like Gumbel-ST which suffers accuracy collapse.

Key Takeaways
  • CAGE method maintains gradient flow while preserving forward alignment in neural networks with logic gate components.
  • Hard-ST with CAGE achieves zero selection gap across all temperatures without accuracy degradation.
  • Gumbel-ST suffers significant accuracy collapse (47-point drop) at low temperatures due to training-inference mismatch.
  • The research demonstrates that Gumbel noise alone does not reduce the discretization gap in neural networks.
  • Logic gate networks serve as an effective testbed for analyzing training-inference alignment issues.
