Reprogramming Large Models with Limited Resources

Date: 2021-10-26

Abstract: This talk introduces model reprogramming, a novel method that enables cross-domain data-limited transfer learning with a pre-trained model. In recent years, the use of foundation models has prevailed in many machine learning applications, such as computer vision and natural language processing. A foundation model is a high-capacity neural network pre-trained on large-scale datasets, and it can be efficiently finetuned to solve downstream tasks. We demonstrate how to reprogram foundation models in image, text, and speech to solve low-resource tasks in medical, molecular, and time-series domains. Finally, we provide a theoretical justification to explain the success of model reprogramming.
