Quick overview
This paper introduces Requential Coding, a compression framework where a teacher model selects training samples for the student model. Unlike parameter-based methods or prequential coding that encode exact data sequences, Requential Coding records only the selections where teacher and student disagree, making code length independent of parameter count and data entropy, often orders of magnitude shorter, with the advantage growing with scale. It reveals compression phenomena unseen by prior methods: under fixed loss, larger models and ensembles compress to much smaller sizes. Plugged into a PAC-Bayes bound, it yields state-of-the-art generalization guarantees for billion-parameter LLMs, tightening with scale in the compute-optimal regime. It also predicts gradual overfitting across epochs and isolates learnable information from random noise, showing lower-entropy text holds far more learnable structure than higher-entropy images.
- Requential Coding selects training samples based on teacher-student disagreement, achieving code length independent of parameter count and data entropy.

FeaturedEquivariant Learning of a Transferable Three-Dimensional Classical Density Functional
等变学习可迁移的三维经典密度泛函
The most striking aspect of this paper is its direct coupling of machine learning to a core problem in statistical mechanics, using equivariant networks to learn a transferable density functional without any labels. For researchers in liquid physics or soft matter, this could be a new paradigm: do we need to run separate simulations for every new system anymore? For AI researchers, it also shows how to embed physical symmetries and variational principles into models rather than just fitting data. I recommend focusing on the methods, especially how equivariance and variational consistency are implemented—that's the real essence.
