Neural Network Compression by Approximate Differential Equivalence

arXiv:2606.01402v1 Announce Type: new Abstract: Neural network compression is commonly achieved by pruning parameters based on local importance scores, e.g., magnitude-based pruning. We propose a complementary approach that compresses models by aggregating neurons with similar functional behavior rather than removing weights independently. Our method encodes a trained network as a polynomial ODE system and applies a lumping method called Approximate Forward Differential Equivalence to identify neurons with approximately matching induced dynamics. A single tolerance parameter, $\varepsilon$, co

Why this matters
Why now

The continuous growth in neural network size and complexity necessitates more efficient compression techniques, making advancements like this highly relevant.

Why it’s important

This research offers a novel approach to neural network compression by focusing on functional equivalence rather than just parameter pruning, potentially leading to more robust and effective model reduction.

What changes

The method shifts from independent weight removal to aggregating neurons with similar dynamic behavior, potentially yielding better compressed models with less performance degradation.
