Learning to Inflate

Rudelius, Tom

Understand

Motivated by machine learning, we introduce a novel method for randomly generating inflationary potentials.

Namely, we treat the Taylor coefficients of the potential as weights in a single-layer neural network and use gradient ascent to maximize the number of e-folds of inflation.
Inflationary potentials "learned" in this way develop a critical point, which is typically a local maximum but may also be an inflection point.
We study the phenomenology of the models along the gradient ascent trajectory, finding substantial agreement with experiment for large-field local maximum models and small-field inflection point models.
