Data-Free Knowledge Transfer: A Survey

Liu, Yuang, Zhang, Wei, Wang, Jun et al.

Understand

In the last decade, many deep learning models have been well trained and made a great success in various fields of machine intelligence, especially for computer vision and natural language processing.

  • To better leverage the potential of these well-trained models in intra-domain or cross-domain transfer learning situations, knowledge distillation (KD) and domain adaptation (DA) are proposed and become research highlights.
  • They both aim to transfer useful information from a well-trained model with original training data.
  • However, the original data is not always available in many cases due to privacy, copyright or confidentiality.
