The paper investigates function spaces defined by self-attention networks without normalization, analyzing their geometric properties using tools from algebraic geometry. The authors focus on polynomial networks and study the identifiability of deep attention by describing generic fibers for an arbitrary number of layers, determining the dimension of the function space. Additionally, they characterize singular and boundary points in a single-layer model. Furthermore, they formulate a conjecture about extending their results to normalized self-attention networks, proving it for a single layer, and numerically verifying it in the deep case.
Low GrooveSquid.com (original content) Low Difficulty Summary
The paper explores how self-attention networks work without normalizing the data. It uses special tools from algebraic geometry to understand the shape of these networks. The researchers want to know if these networks can learn complex patterns and identify specific features. They analyze a type of network with many layers, called deep attention, and figure out what makes it unique. They also study single-layer models and find that some points are special because they change how the network works. Finally, they make a guess about how to apply their findings to networks that do normalize the data.
