The three “integration” projects at SCIoI focus on assembling the diverse components of intelligence into a cohesive and comprehensive framework. While decomposition aids in breaking down the complexity of intelligence into manageable parts, integration is the pivotal process of reassembling these components to elucidate the holistic nature of intelligence. The Integration projects at SCIoI leverage the concept of “weak decomposability” to unify diverse intelligence components effectively. Unlike traditional approaches, which decompose the study of intelligence into smaller parts, SCIoI recognizes the importance of weak decomposability in creating functional components that can be integrated into a larger intelligent system. Integration hackathons provide dynamic forums for researchers to identify interfaces, solve challenges, and implement high-level behaviors, offering valuable feedback to individual projects. The project aims to foster collaboration among researchers from various disciplines, bringing together their unique perspectives to create a unified understanding of intelligence. Through integration, the cluster aims to unravel the holistic nature of intelligence, paving the way for groundbreaking discoveries in artificial and natural intelligence.
