Researchers have introduced DeCO, a novel method for dataset distillation aimed at improving fine-grained visual classification. Unlike previous methods that focus on global image statistics, DeCO prioritizes preserving localized evidence such as object parts and textures. The technique formulates distillation as budgeted discriminative-evidence preservation, using a pretrained teacher model to identify informative image patches, diversify coverage, and organize these regions into class-wise evidence banks. These banks are then composed into compact grid images for training downstream models. Experiments on datasets like CUB-200-2011, FGVC-Aircraft, and Stanford Cars demonstrate DeCO's superior performance compared to existing coreset and dataset distillation baselines. AI
