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.^[3]

Biography

Michalski was born in Kalusz near Lvov on 7 May 1937.

He received an equivalent of Bachelor of Science degree in Electrical Engineering at the Universities of Technology in Kraków and Warsaw in 1959; obtained M.S. Computer Science at the Polytechnic Institute of St. Petersburg in 1961; and Ph.D. in Computer Science at the Silesian University of Technology, Gliwice in 1969. In the period 1962–1970 he worked at the Institute of Automation of the Polish Academy of Sciences (PAS) in Warsaw, during which he and Jacek Karpiński developed an early successful learning system for recognizing handwritten alpha-numeric characters.

He emigrated to America in 1970, worked at the University of Illinois at Urbana-Champaign until moved with his research group to the George Mason University in 1988. Although leaving Poland, he worked part-time at the Institute of Computer Science of PAS in Warsaw.

Ryszard S. Michalski died on 20 September 2007 from cancer at his home in Fairfax.^[3]

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.^[4]

Work

Michalski influenced wide areas, notably in machine learning, but also in the broadly understood areas of data analysis and knowledge discovery.^[5] Some of his offspring are listed below. (See more on his homepage at GMU.)

Honors and awards

Michalski was elected to Foreign Member of the Polish Academy of Sciences in 2000^[6] and Fellow of AAAI.^[1] Poland President honored him with the Officer's Cross of the Order of Merit of the Republic of Poland in July 2007.

Selected works

Michalski was prolific author of scientific works on various topics in computer science, including machine learning, artificial intelligence, and human plausible reasoning. He wrote, co-wrote, or co-edited more than 350 research publications and more than one dozen books. Some of which are listed below. (See more on his homepage at GMU.)
