Towards Cognitive AI Systems: a Survey and Prospective on Neuro-Symbolic AI
This is a survey paper, so it is incremental, summarizing existing work for researchers in AI.
The paper surveys neuro-symbolic AI as a paradigm to address challenges like lack of explainability and high data needs in current AI systems, highlighting its potential to enhance interpretability, robustness, and learning efficiency.
The remarkable advancements in artificial intelligence (AI), primarily driven by deep neural networks, have significantly impacted various aspects of our lives. However, the current challenges surrounding unsustainable computational trajectories, limited robustness, and a lack of explainability call for the development of next-generation AI systems. Neuro-symbolic AI (NSAI) emerges as a promising paradigm, fusing neural, symbolic, and probabilistic approaches to enhance interpretability, robustness, and trustworthiness while facilitating learning from much less data. Recent NSAI systems have demonstrated great potential in collaborative human-AI scenarios with reasoning and cognitive capabilities. In this paper, we provide a systematic review of recent progress in NSAI and analyze the performance characteristics and computational operators of NSAI models. Furthermore, we discuss the challenges and potential future directions of NSAI from both system and architectural perspectives.
