LG AI Research introduces Projection Regret, a method for novelty detection using diffusion models that reduces background bias by measuring semantic distance between original and diffusion-edited images.

## Evidence

Verbatim from https://www.lgresearch.ai/blog/view?seq=491:

> This post will introduce the Projection Regret [1] study conducted by LG AI Research, and also take a look at other good studies related to score-based generative modelling and diffusion models.
