DeCO: Discriminative Evidence Composition for Fine-Grained Dataset Distillation

Read the original on arXiv Computer Vision →

DeCO: Discriminative Evidence Composition for Fine-Grained Dataset Distillation introduces a method that compresses large training sets into compact synthetic sets while preserving fine-grained visual classification cues. It uses attention rollout from a pretrained TransFG teacher to locate informative patches, applies spatial diversification to avoid redundancy, and organizes these patches into class-wise evidence banks that are packed into grid-composed images. Experiments on CUB-200-2011, FGVC-Aircraft, and Stanford Cars demonstrate that DeCO outperforms existing coreset and dataset-distillation baselines across various images-per-class budgets.

Rethinking Dataset Distillation for Classification: Do Distilled Sets Outperform Coresets?

arXiv:2606. 18209v1 Announce Type: new Abstract: Dataset distillation (DD) has emerged as a prominent approach in data centric machine learning, aiming to synthesize compact training sets for efficient training by compressing the information in large datasets into a small number of synthetic samples.

Grid-Preserving Knowledge Distillation: Transferring Convolutional Inductive Bias to Vision Transformers under Data Scarcity

Vision Transformers underperform convolutional networks when training data is scarce, and distilling convolutional inductive biases from a CNN teacher is an effective remedy that leaves the deployed model unchanged. General-purpose feature distillation, however, transfers little in this setting.

Breaking the Geometric Bottleneck: Contrastive Expansion in Asymmetric Cross-Modal Distillation

The paper investigates how knowledge distillation from Vision Transformers to smaller CNNs can cause dimensional collapse in the student’s representation space. Using SVD and Shannon entropy, the authors show that cosine‑based distillation leads to a drastic reduction in effective rank, while adding an InfoNCE objective can double the rank but harms downstream accuracy due to signal dilution. They further demonstrate that a label‑aware contrastive objective (Supervised Contrastive distillation) can maintain or improve accuracy without unnecessary rank expansion, indicating that effective rank alone is not a reliable indicator of representation quality.
