FLOWER: A Flow-Matching Solver for Inverse Problems

Mehrsa Pourya, Bassam El Rawas, Michael Unser

ICLR 2026poster

We introduce Flower, a solver for linear inverse problems. It leverages a pre-trained flow model to produce reconstructions that are consistent with the observed measurements. Flower operates through an iterative procedure over three steps: (i) a flow-consistent destination estimation, where the vel…

DEALing with Image Reconstruction: Deep Attentive Least Squares

Mehrsa Pourya, Erich Kobler, Michael Unser, Sebastian Neumayer

ICML 2025poster

State-of-the-art image reconstruction often relies on complex, abundantly parameterized deep architectures. We propose an alternative: a data-driven reconstruction method inspired by the classic Tikhonov regularization. Our approach iteratively refines intermediate reconstructions by solving a seque…
