Artificial General Intelligence (AGI) refers to the development of AI that is comparable to human intelligence. In the past, AI focused on domain-specific problems and special-purpose solutions but has now shifted back to the goal of achieving general-purpose intelligent systems. Various approaches to AGI have emerged, including replicating brain structure, imitating human behavior, problem-solving capability, cognitive functionality, and rationality. Different AGI projects have different interpretations of intelligence and utilize various techniques such as logic, probability theory, neural networks, and robotics. Despite concerns about AGI, researchers believe that progress in AGI research will benefit humanity. Several representative AGI projects are highlighted, including ACT-R, AERA, and AIXI.
