Geometric Reasoning in the Embedding Space
This paper investigates how Graph Neural Networks (GNNs) and Transformers develop internal spatial understanding by solving geometric constraint satisfaction problems (CSPs) on a discrete 2D grid. The study reveals that GNNs are more suitable for structured constraint reasoning, developing interpretable internal representations that mirror geometric structures. Point embeddings self-organize into 2D grid structures, and models iteratively construct hidden geometric figures within their embedding spaces. The research also shows that reasoning complexity correlates with prediction accuracy and that models use an iterative refinement process. These insights contribute to understanding structured reasoning and neural network interpretability, especially given the GNN's superior scalability to larger problems compared to Transformers.

Unpacking Geometric Reasoning
The core of our AI model's intelligence lies in its ability to internalize and operate on geometric principles. We've identified several key mechanisms.
Embedding Organization
Iterative Refinement
Structured Understanding
GNN Superiority
Our models, particularly GNNs, spontaneously organize point embeddings into a 2D grid-like structure in high-dimensional space. This self-organization mirrors the actual geometric layout of the problems, demonstrating an implicit understanding of spatial relationships without explicit supervision. This phenomenon is observed during training and strengthens with iterative refinement.
The AI solves complex geometric problems through an iterative refinement process. Unknown point embeddings progressively move and adjust within the embedding space, converging towards configurations that satisfy the given constraints. This resembles a continuous optimization process, where initial approximations are refined over multiple message-passing iterations.
The GNN architecture develops a deep, structured understanding of geometric constraints. Constraint embeddings encode specific constraint types (e.g., Square, Midpoint, Reflection) and their properties, even capturing temporal information about the solution progression. This allows the network to process and resolve dependencies effectively.
Graph Neural Networks (GNNs) consistently outperform Transformers for these structured geometric reasoning tasks. They demonstrate superior scalability to larger grids and higher problem complexity, along with more efficient training. This indicates that their graph-based message-passing mechanism is inherently better suited for problems with explicit relational structures.

Iterative Solution Emergence in Practice
Consider a complex geometric CSP involving squares and translations. Initially, the unknown points are randomly positioned. Through successive GNN iterations, we observe:
- Early Stages (Iter 0-5): Embeddings are pulled towards the manifold of fixed points, forming a coherent, albeit approximate, geometric configuration.
- Mid Stages (Iter 6-12): Simpler constraints, like single translations, are resolved first. The system prioritizes establishing foundational relationships.
- Late Stages (Iter 13-15+): More complex constraints, such as squares dependent on previously determined points, are refined. The quadrilaterals gradually converge to exact squares, demonstrating the GNN's ability to handle interdependent constraints.
