Transfer learning (TL) is a powerful technique in machine learning. Here, a pre-trained model carrying experience with similar types of tasks is applied to improve the efficacy of the base model with similar tasks. In current days, TL is widely applied in disease classification, identification of malignant cells and natural language processing. It is a promising area with high potential. The domain shifts, negative transfer, and overfitting are the major challenges and limitations of TL. In future, TL will overcome its limitations and will be widely applied in pathology.

摘要

Transfer learning (TL) is a powerful technique in machine learning. Here, a pre-trained model carrying experience with similar types of tasks is applied to improve the efficacy of the base model with similar tasks. In current days, TL is widely applied in disease classification, identification of malignant cells and natural language processing. It is a promising area with high potential. The domain shifts, negative transfer, and overfitting are the major challenges and limitations of TL. In future, TL will overcome its limitations and will be widely applied in pathology. The present chapter discusses the basic principles, strengths, limitations and applications of transfer learning.
