Findings
- IC-1099AdamW-pretrained vision models (ViTs, ConvNeXt) have disproportionately large embedding-layer gradients at initialization, causing SGD fine-tuning to degrade OOD accuracy by up to 15% relative to AdamW
- IC-1290CLIP, DINO, and DINOv2 as zero-shot natural baselines score below the 50% chance level on Bongard-OpenWorld due to adversarial query selection
- IC-1497LLaMA-7B's frozen transformer block amplifies informative visual tokens, producing feature activations with higher Miou against ground-truth segmentation masks than both the baseline ViT and the model's own attention scores [context]
- IC-357Off-the-shelf foundation models (DINO, CLIP, DINOv2, ViT) exhibit higher variance in their cosine similarity distributions than dataset-specific models, reducing the discriminative power of cosine similarity retrieval
- IC-646DINOv2, DeiT-III, and OpenCLIP repurpose approximately 2% of patch tokens in low-informative background areas as internal registers, discarding local patch information while aggregating global image information; DINO does not exhibit this behaviour
- IC-647DINOv2's feature-map artifacts cause it to be incompatible with the LOSt unsupervised object discovery method, scoring far below DINO
