Layerwise Progressive Freezing: A Training Scaffold for Depth-Scalable Binary Networks

arXiv:2606.27759v1 Announce Type: new Abstract: Training binary neural networks (BNNs) from scratch is dominated by the straight-through estimator (STE), whose forward/backward mismatch produces severe accuracy degradation as networks deepen. We study an orthogonal axis: when and where binarization is enforced during training. We introduce StoMPP (Stochastic Masked Partial Progressive Binarization), which gradually replaces clipped weights and activations with their hard binary counterparts layer by layer from input to output, using stochastic partial masks with soft refresh. StoMPP delivers t

Why this matters
Why now

Ongoing research into more efficient neural network training methods continues to address the computational demands of AI, especially for deployment on resource-constrained devices.

Why it’s important

Improved binary neural network training can significantly reduce memory and computational footprint, enabling advanced AI capabilities in edge devices and specialized hardware.

What changes
