The success of traditional machine learning techniques is highly dependent on the assumption that the training and test data are drawn from independent and identical distributions. This assumption provides a theoretical guarantee and serves as a foundation for the high performance of traditional methods. However, in real-world applications, the performance of well-trained models often suffers from degradation due to the violation of this fundamental assumption. Factors such as environment, equipment, and human activity can easily lead to significant differences in data distribution across training and test data, which poses challenges to the generalization ability of models.One direction of addressing the above problem is Domain Generalization, which aims to enhance the generalization ability of trained models, allowing them to perform well even on unseen test data with different distributions. In this thesis, we conduct a comprehensive review of previous work, focusing on the theoretical foundations, algorithms, and workflows associated with the representation learning-based domain generalization algorithms. We identify the gap between previous theoretical work and practical algorithms, and propose a novel theory to bridge this gap. We also explore the weakness of some domain generalization principles and propose an algorithm as a potential solution. In addition to focusing on algorithms, we recognize the importance of model selection for methods designed for domain generalization. In light of this, we propose a novel model selection method that takes into account the unique characteristics and challenges associated with domain generalization. This selection method considers the complexities of domain shifts and ensures the reliable assessment of model generalization across different domains. By incorporating this validation method into the evaluation process, we can gain more insights into the application of domain generalization algorithms to practical problems.Through this thesis, we contribute to the field of domain generalization by bridging the gap between previous theory and practice, offering potential solutions to address the failure cases observed in certain domain generalization methods and emphasizing the importance of considering the workflow of the domain generalization problem. The proposed theoretical advancements, algorithms, and validation method collectively aim to enable machine learning models to generalize effectively across diverse real-world domains with varying data distributions.
