Summary

A new unified framework characterizes conservation laws for modern neural architectures, addressing a gap in understanding gradient descent dynamics in over-parameterized models. Published on 2026-06-16, this work extends existing knowledge beyond linear and ReLU networks to contemporary designs. The framework specifically covers feedforward networks incorporating GELU, SiLU, and SwiGLU activations, along with multihead attention mechanisms utilizing sinusoidal and rotary positional encodings. Furthermore, it encompasses Mixture-of-Experts architectures, analyzing them under various gating designs. The theoretical predictions of these invariants are empirically validated through supporting experiments, providing a deeper insight into the implicit bias of these complex models.

Key takeaway

For AI Scientists and Machine Learning Engineers investigating model training dynamics, this framework offers critical insights into the implicit bias of modern architectures. You should consider how these newly characterized conservation laws for GELU, SiLU, SwiGLU, multihead attention, and MoE models impact your understanding of gradient flow. This deeper theoretical foundation can inform your design choices and debugging strategies for over-parameterized neural networks, potentially guiding more stable and predictable model development.
