Jack Sklansky

Jack Sklansky was an engineer who taught at UC Irvine for 28 years and worked on pattern recognition, computer design and computer-assisted medical diagnosis. The child of Russian Jewish immigrants, he grew up in Brooklyn and earned a PhD in engineering at Columbia University in 1955. His work at UC Irvine included the 1975 paper "Finding circles by an array of accumulators", the 1981 book Pattern Classifiers and Trainable Machines, and a 1987 study of feature selection with Iman Foroutan. In 1994, the International Association for Pattern Recognition named him a Fellow for contributions to pattern recognition, machine vision and medical imaging. He died in Palo Alto in 2018.

Timeline

  1. 1928–1955

    A Columbia engineering doctorate

    Born in November 1928 to Russian Jewish immigrants, he grows up in Brooklyn and attends the City College of New York. He earns a PhD in engineering at Columbia University in 1955 with the dissertation "Network Compensation of Error-sampled Feedback Control Systems", advised by John Ralph Ragazzini.

  2. 1963–1969

    Automata and threshold learning

    In 1963, he publishes "Determination of the Final State of an Automaton Whose Initial State Is Unknown" and an annotated bibliography on NOR and NAND logic in IEEE Transactions on Electronic Computers. His paper "The dynamics of time-varying threshold learning" appears in Information and Control in 1969.

  3. 1966

    Teaching at UC Irvine

    In 1966, he moves to southern California and begins 28 years of teaching at UC Irvine, working on pattern recognition, computer design and computer-assisted medical diagnosis. A research program and graduate course on trainable classifiers run at UCI from 1966, with the research forming part of the UCI Pattern Recognition Project.

  4. 1972–1975

    Finding circles with accumulators

    In 1972, he publishes "Measuring Concavity on a Rectangular Mosaic" and "Minimum-Perimeter Polygons of Digitized Silhouettes" in IEEE Transactions on Computers. His doctoral student Dana Ballard completes a PhD at UC Irvine in 1974, and "Finding circles by an array of accumulators" appears in Communications of the ACM in 1975.

  5. 1981

    A book on trainable classifiers

    With Gustav N. Wassel, he writes Pattern Classifiers and Trainable Machines, published in 1981. The book is written as a guide for designers of pattern classifiers and as a text for graduate courses in engineering or computer science.

  6. 1987

    Feature selection for classifiers

    In 1987, he and Iman Foroutan publish "Feature Selection for Automatic Classification of Non-Gaussian Data" in IEEE Transactions on Systems, Man, and Cybernetics.

  7. 1994

    An IAPR fellowship

    The International Association for Pattern Recognition names him a Fellow in 1994 for contributions to pattern recognition, machine vision and medical imaging and for service to the IAPR.

  8. 2018

    Death in Palo Alto

    He dies in Palo Alto in September 2018, a few weeks before his 90th birthday.
