On the Emergence of Syntax by Means of Local Interaction

Zichao Wei · arXiv:2604.17857, 2026

An 18,658-parameter 2D NCA, trained with 1-bit supervision, spontaneously develops internal structure aligned with the CKY parsing algorithm (Pearson r ≈ 0.71).

On the Mirage of Long-Range Dependency, with an Application to Integer Multiplication

Zichao Wei · arXiv:2603.29069, 2026

321 parameters, 683× length generalization. Long-range dependency in multiplication is a mirage produced by computational spacetime choice.

On the Spatiotemporal Dynamics of Generalization in Neural Networks

Zichao Wei · arXiv:2602.01651, 2026

Three physics-inspired postulates derive the SEAD architecture. Validates on parity, addition (L=16 → L=1,000,000 at 100%), and Rule 110.

Using Eye Tracking to Investigate What Native Chinese Speakers Notice about Linguistic Landscape Images

Zichao Wei, Yewei Qin · arXiv:2312.08906, 2023

Eye-tracking study on linguistic landscape perception. Native Chinese speakers fixate longer and more frequently on linguistic elements than general landscape features, attributed to higher information density.
