Bull, K., He, Y. ORCID: 0000-0002-0787-8380, Jejjala, V. & Mishra, C. (2019). Getting CICY high. Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 795, pp. 700-706. doi: 10.1016/j.physletb.2019.06.067


Supervised machine learning can be used to predict properties of string geometries with previously unknown features. Using the complete intersection Calabi–Yau (CICY) threefold dataset as a theoretical laboratory for this investigation, we use low h1,1 geometries for training and validate on geometries with large h1,1. Neural networks and Support Vector Machines successfully predict trends in the number of Kähler parameters of CICY threefolds. The numerical accuracy of machine learning improves upon seeding the training set with a small number of samples at higher h1,1.
