Lifelong Forgetting: A Critical Ingredient of Lifelong Learning, and Its Implementation in the OpenCog Integrative AI Framework

Of all the aspects differentiating lifelong learning from shorter-term, more specialized learning, perhaps none is more central than forgetting – or, to frame the issue more generally and technically, ”memory access speed deprioritization.” This extended abstract reviews some of the ideas involved in forgetting for lifelong learning systems, and briefly discusses the forgetting mechanisms used in the OpenCog integrative cognitive architecture.
