Outline of Final Research Achievements

This study aims to construct a framework for statistical learning using high-dimensional and large-scale multi-domain data. In the era of big data, diverse and complex data with different sizes, dimensions, and representation formats can be collected across various domains. However, there exists a paradox wherein the relationships between domains are often unclear, leading to a knowledge deficit as data volume increases. To overcome this, it is crucial to extract and integrate features of data while considering the inter-domain relationships. This research focuses on formalizing this task with a focus on inter-domain relationships. It seeks to develop modeling techniques and machine learning algorithms for multi-domain data with heterogeneous structures, aiming to advance the theoretical understanding in this field.
