Defining and Generating Compositional Structure

The paper introduces a formal definition of compositional structure based on algorithmic information theory, stating that such structure emerges when combined parts reveal shared patterns not evident when modeled separately. It applies this definition across scales to identify where compositionality arises and then inverts the framework to generate new compositional objects by optimizing over strings and images. The resulting artifacts display clear hierarchical reuse and part‑whole organization, indicating that the definition captures genuine compositionality rather than generic complexity or regularity.

A Theoretical Analysis of Provable Compositional Generalization in Neural Networks: A Necessary and Sufficient Condition

The paper presents a necessary and sufficient condition for provable compositional generalization in neural networks, identifying two key principles: structural alignment and unambiguous minimized representations. It rigorously proves this condition, verifies it in Lean 4, and demonstrates its applicability in few-shot settings, including the SCAN jump task. The authors also outline an algorithmic approach and illustrate it with a minimal example, all derived purely from mathematical analysis without empirical validation.

Atomic Units of X: The Compression Layer of Intelligence

This paper proposes a theoretical framework for understanding intelligence as a process of atomic compression and compositional reuse. We argue that cognitive, biological, computational, and organizational systems achieve scalable intelligence by decomposing complex phenomena into reusable atomic units that can be recombined into higher-order structures.

Structure, Not Sequence: Tracking and Validating Folding Mechanisms in ESMFold's Trunk with Sparse Autoencoders

The paper investigates how ESMFold’s folding trunk transforms amino‑acid sequences into 3D protein structures by using sparse autoencoders (SAEs) to uncover interpretable features. It first analyzes representation distributions across modules and recycles to identify distinct spatial computations, then shows that single representations carry inherited semantics while pair representations compute pairwise geometry. Finally, the authors use a reasoning language model and gradient‑based attribution to trace concept composition across blocks, verifying alignment with known biochemistry and demonstrating that the trained sparse dictionaries can predict the model’s fold quality, thereby turning the black‑box trunk into an interpretable, scientifically verifiable circuit.

How Molecular Generative Models Organize Molecular Identity

arXiv:2608. 06956v1 Announce Type: new Abstract: Generative models for matter are often evaluated as samplers over output representations, and their latent spaces are commonly used as proxies for navigating chemical space.
