LUMIC

Latent diffUsion for Multiplexed Images of Cells is a diffusion model pipeline developed to generate the high-content fluorescent microscopy images of different cell type and chemical compound interactions. LUMIC combines diffusion models with DINO (self-Distillation with NO labels), a vision-transformer based, self-supervised method that can be trained on images to learn feature embeddings, and HGraph2Graph, a hierarchical graph encoder-decoder to represent chemicals.
