Single-loop methods for bilevel parameter learning in inverse imaging
Ensio Suonperä, Tuomo Valkonen
Bilevel optimisation is used in inverse imaging problems for hyperparameter learning/identification and experimental design, for instance, to find optimal regularisation parameters…

Linearly convergent bilevel optimization with single-step inner methods
Ensio Suonperä, Tuomo Valkonen
We propose a new approach to solving bilevel optimization problems, intermediate between solving full-system optimality conditions with a Newton-type approach, and treating the inn…
