OpenCog Cognitive Architecture


OpenCog is an open-source artificial intelligence project that is designed to build a unified, large-scale artificial general intelligence (AGI) system. Its cognitive architecture is based on principles and mechanisms that enable the development of AGI systems that can learn and adapt to new tasks. The OpenCog architecture includes the AtomSpace, a distributed database that represents knowledge and information, as well as AI and machine learning tools and techniques such as probabilistic reasoning and evolutionary computation. It has a flexible, modular design that allows different components to be combined and used in various ways to build complex AI systems and applications. It is intended to be used in a variety of domains and has the potential to enable the development of advanced AGI systems.
