ThinkingNode* is a breakthrough Artificial Intelligence (AI) technology that empowers human thinking by providing exponential thinking capabilities. Instead of using data to discover correlations, ThinkingNode works directly with human expertise to build thinking engines capable of representing causation to produce sophisticated reasoning for solving complicated problems without asking the expert to explicitly code for all inference combinations. Further, ThinkingNode is a distributed AI system that goes beyond the traditional mono-inference engine of expert/symbolic systems; each concept is a mini-inference engine allowing the finest level of tuning for the inference strategy. ThinkingNode provides a Thinking-as-a-Service (TaaS) Platform to enhance, share, and make human expertise a tangible asset for any organization. * ThinkingNode is the 2nd generation of an AI technology developed by Khai Minh Pham (MD, PhD in Artificial Intelligence). He has been in the field of AI for 25 years. The 1st generation has been used by his first company that has been acquired for US$400 Million.
