DeepSeek’s “Mathematical Tight‑Fit” Tames AI: Constraints Drive Performance Gains

DeepSeek’s new mHC architecture replaces unconstrained hyper‑connections with manifold‑constrained doubly‑stochastic matrices, stabilizing large‑scale training, reducing signal explosion from 3000× to 1.6×, and delivering consistent accuracy improvements across BBH, DROP, GSM8K, and MMLU benchmarks while adding only 6.7% training overhead.
