1. 领域适应(Domain Adaptation)是什么?
根据维基百科的解释,领域适应(DA)指的是在源域上训练一个模型,使得模型能够在目标域上也取得较好效果,这个目标域是一个与源域不同但相关的域。
Domain adaptation is a field associated with machine learning and transfer learning. This scenario arises when we aim at learning from a source data distribution a well performing model on a different (but related) target data distribution
