Research Accomplishment 2021: Neuro-Symbolic Models and World Simulators for Machine Common Sense

From a very young age, humans are able to grasp basic physical and social principles that govern their environment. For example, at around 4 months of age, babies understand that an object does not vanish out of existence even when it is out of sight. Often such principles are not labeled or taught in a direct supervised manner and we refer to them as common sense. As humans grow and develop the ability to communicate in natural language, their common sense understanding develops as well. For example, adults possess an intuitive understanding of Newtonian physics and are able to make accurate predictions and answer questions about dynamic scenes involving interactions between several objects. Common sense is necessary for humans, and other animals, to successfully interact with their environment and achieve their goals, and it is often a prerequisite for learning and solving higher-level tasks, e.g. changing a flat tire. It is likely that the road to general AI and embodied agents will require developing models and systems that have common sense. This accomplishment is for a body of work that led to a significant scientific impact, including more than 20 publications in top tier conferences, invited talks and organized workshops and patents, as well as [budget redacted since confidential, but a multi-million] 4-year DARPA contract, several open source projects including a highly realistic simulation environment for training and testing AI agents, numerous released datasets and benchmarks, and media coverage. This impact is a result of a long-term, cross-organizational and multi-disciplinary teaming effort between researchers and engineers from IBM and our academic partners at MIT, Harvard and Stanford.
