Ryszard S. Michalski

Ryszard Stanisław Michalski (May 7, 1937 – September 20, 2007) was a Polish-American computer scientist. Michalski was Professor at George Mason University and a pioneer in the field of machine learning.

Academic life Michalski was cofounder of Machine Learning and Inference Laboratory at George Mason University. He earned a patent for the university with Learnable Non-Darwinian Evolution Model (LEM), a form of evolutionary computation, in 2003.

He cofounded the Journal of Machine Learning in 1986 and helped organize the first international multistrategy machine learning conferences in 1991.

Work Michalski influenced wide areas, notably in machine learning, but also in the broadly understood areas of data analysis and knowledge discovery. Some of his offspring are listed below. (See more on his homepage at GMU.) Learning system for handwritten character recognition (1966) AQ algorithm (1969) Conceptual clustering (1980) Multistrategy learning (1984) Logic of human plausible reasoning-with Alan Collins (1979–1989) Multistrategy data mining/Knowledge segment (1991) Data-driven constructive induction (1991) Hypothesis-driven constructive induction (1991) Inferential theory of learning (1991) Learning trees from rules (1993) Natural induction (1996) Learnable Evolution Model-LEM (1997) Data Inferencing (1998) Knowledge Mining (2001) Attributional calculus (1998/2004)

Honors and awards Michalski was elected to Foreign Member of the Polish Academy of Sciences in 2000 and Fellow of AAAI. 1986. (with Brian C. Falkenhainer) Integrating quantitative and qualitative discovery: The ABACUS system. Machine Learning: Volume 1, Issue 4, pp 367–401.
