Distinguishing Elliptic Fibrations with AI

Understand

We use the latest techniques in machine-learning to study whether from the landscape of Calabi-Yau manifolds one can distinguish elliptically fibred ones.

• Using the dataset of complete intersections in products of projective spaces (CICY3 and CICY4, totalling about a million manifolds) as a concrete playground, we find that a relatively simple neural network with forward-feeding multi-layers can very efficiently distinguish the elliptic fibrations, much more so than using the traditional methods of manipulating the defining equations.
• We cross-check with control cases to ensure that the AI is not randomly guessing and is indeed identifying an inherent structure.
• Our result should prove useful in F-theory and string model building as well as in pure algebraic geometry.
