Krzysztof J. Cios

Also known as Krys Cios

Krzysztof Cios is a computer scientist whose research spans machine learning, data mining and biomedical informatics. Born in Dębica in 1950, he earned degrees at AGH University, the Polish Academy of Sciences and the University of Toledo, then worked at Toledo and the University of Colorado Denver before joining Virginia Commonwealth University in 2007. His 1998 and 2007 books explain data-mining methods and frame the field through knowledge discovery. At VCU, he chaired computer science as the university announced a joint doctoral program with the University of Córdoba. He became an AIMBE Fellow in 2017 and an IEEE Fellow in 2020, and he is a professor emeritus in VCU computer science.

From the biography.

  1. The company share of AI researchers’ top papers was 31% in 2020–2024 and 8% in 1970–1974Includes University of Colorado Denver. We estimate where the people shaping AI worked when their most-cited papers appeared: the company share was 31% in 2020–2024 and 8% in 1970–1974, and Google led all organizations in 2020–2024.
  2. The United States employs an estimated 48% of people shaping AIIncludes Polish Academy of Sciences. We estimate where the people shaping AI work today, how universities, companies and research institutes split across countries, and how country shares have changed since the 1960s.
  3. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionIncludes Polish Academy of Sciences. We estimate where the people shaping AI studied and where their careers led. Massachusetts Institute of Technology leads with 467 former students, including 291 recorded doctorates.
  4. Google has the highest combined h-index among AI organizationsIncludes Polish Academy of Sciences. We estimate that Google holds the highest combined h-index at 8,016, while universities account for 73% of the deduplicated total across AI organizations.
