WaveDiff with wavefront feature projection recovers WFE from noisy undersampled in-focus observations at ~3% error, a tenfold improvement over the prior version.
Proposes a structured transform learning method via inexact proximal optimization with a closed-form projection, claiming SOTA results on doubly sparse learning at lower cost than dense variants.
SeqLoRA applies bilevel optimization to sequential LoRA adaptation for continual multi-concept text-to-image generation with theoretical bounds on forgetting and interference.
