Wikipedia for Smart Machines and Double Deep Machine Learning
This work tackles the problem of knowledge-blind AI for complex applications such as medical diagnosis, offering a paradigm shift from Big Data to Big Knowledge, though it is incremental in integrating existing methods.
The paper addresses the limitations of data-centric deep learning for non-transactional AI applications like medical diagnosis by proposing the Wikipedia for Smart Machines initiative to build repositories of reusable knowledge structures (ReKopedia) and a Double Deep Learning approach to integrate data-centric algorithms with knowledge-based reasoning, illustrated with a project for diagnosing about 1,000 disorders.
Very important breakthroughs in data centric deep learning algorithms led to impressive performance in transactional point applications of Artificial Intelligence (AI) such as Face Recognition, or EKG classification. With all due appreciation, however, knowledge blind data only machine learning algorithms have severe limitations for non-transactional AI applications, such as medical diagnosis beyond the EKG results. Such applications require deeper and broader knowledge in their problem solving capabilities, e.g. integrating anatomy and physiology knowledge with EKG results and other patient findings. Following a review and illustrations of such limitations for several real life AI applications, we point at ways to overcome them. The proposed Wikipedia for Smart Machines initiative aims at building repositories of software structures that represent humanity science & technology knowledge in various parts of life; knowledge that we all learn in schools, universities and during our professional life. Target readers for these repositories are smart machines; not human. AI software developers will have these Reusable Knowledge structures readily available, hence, the proposed name ReKopedia. Big Data is by now a mature technology, it is time to focus on Big Knowledge. Some will be derived from data, some will be obtained from mankind gigantic repository of knowledge. Wikipedia for smart machines along with the new Double Deep Learning approach offer a paradigm for integrating datacentric deep learning algorithms with algorithms that leverage deep knowledge, e.g. evidential reasoning and causality reasoning. For illustration, a project is described to produce ReKopedia knowledge modules for medical diagnosis of about 1,000 disorders. Data is important, but knowledge deep, basic, and commonsense is equally important.
