From ontology to oncology: Deep science for medical AI
Safe engineering backed by deep science is especially needed in hazard-prone areas that affect our lives
I have dwelled in this column before on the need for us to allow mathematicians to pierce the frontiers of artificial intelligence (AI). More recently, I wrote about Cyc, an attempt to create a vast ontological representation of common-sense knowledge, for use in everyday applications. Ontology, though a big word, simply means a set of concepts and categories in a subject area or domain that shows their properties and the relations between them. The top-down approach of machine learning, which allows the machine to better its own AI applications as more data arrive, should still use a bottom-up ontological approach such as Cyc in order to be truly useful in everyday applications.
