초록/해제: 요약The field of artificial intelligence (AI) has garnered increasing attention in the realms of public health and conservation due to its potential to characterize complex dynamics and facilitate difficult decision-making. My research focuses on developing AI solutions, utilizing machine learning and optimization techniques, to provide actionable decisions for deployment and create positive social impact. This endeavor necessitates the integration of new algorithmic and learning paradigms, combining machine learning techniques to extract knowledge from data and optimization techniques to leverage domain knowledge and scale up to larger problem sizes. In this thesis, I present methodological and theoretical contributions in the integration of optimization into machine learning problems, including supervised learning, online learning, and multi-agent systems, with the aim of improving learning performance and scalability by harnessing the knowledge encoded in optimization tasks. Notably, this thesis introduces the first decision-focused learning to integrate sequential problems into the learning pipeline to provide feedback from decision-making processes and significantly reduce computation costs, thus enabling applications in large-scale public health problems. The proposed algorithm has been successfully applied in a field study and deployment in a maternal and child health program, marking the first successful implementation of decision-focused learning in the real world. Currently, the proposed algorithm is used by over 100,000 beneficiaries in India to enhance engagement with health information and translate algorithmic contributions into tangible social impact.
