🧠Researchers present Chain-of-Models Pre-Training (CoM-PT), a novel method that accelerates vision foundation model training by up to 7.09X through sequential knowledge transfer from smaller to larger models in a unified pipeline, rather than training each model independently. The approach maintains or improves performance while significantly reducing computational costs, with efficiency gains increasing as more models are added to the training sequence.

🧠Researchers demonstrate that language models develop semantic role understanding (who-did-what-to-whom comprehension) primarily during pre-training, though fine-tuning still improves performance. Using linear probes on frozen transformer models, they find semantic role information emerges from language modeling objectives alone, with representation structure becoming more distributed as models scale.
