The proposed paper explores the idea that smaller models can benefit from the results achieved by larger pre-trained models without going through the costly process of pre-training themselves. Instead, they can be distilled on a specific task using a teacher model, achieving similar or better performance compared to if they were pre-trained and fine-tuned. The connection between knowledge distillation and contrastive learning is established, allowing for various model architecture pairings and contrasting learning algorithms to be applied. The paper demonstrates this paradigm using open-source models and a novel distillation algorithm that leverages the alignment/uniformity perspective of contrastive learning. Additionally, it highlights a training method for small models that is up to 94% faster than standard pre-training without sacrificing performance.

This paper shows how smaller models can get better results by “borrowing” from larger, already-trained models. Instead of spending lots of time and computing power to train their own models, they can learn from the bigger models in a way that’s surprisingly effective. The researchers found that when a small model is taught by a large pre-trained model on a specific task, it can perform just as well or even better than if it had been trained itself. This discovery opens up new possibilities for using large-scale models to improve smaller ones, and could be especially helpful for people who want to use these big models but don’t have the resources to train their own.
