English computer scientist in New Zealand (born 1947)
Ian Hugh Witten (4 March 1947 – 5 May 2023) was a
computer scientist at the
University of Waikato , New Zealand.
[1]
[5]
[6] He was a
Chartered Engineer with the
Institute of Electrical Engineers .
[7]
Early life and education
Witten was born in
Horsham ,
Sussex , England, on 4 March 1947.
[8] He graduated from the
University of Cambridge with a BA and MA (First Class Honours) in mathematics in 1969 and an
Master of Science degree in mathematics and computer science from the
University of Calgary , where he was a
Commonwealth Scholar , in 1970.
[9] He received his
PhD in 1976 from the
University of Essex .
[10]
In 1971, Witten married Pamela Foden at the Chapel of
Gonville and Caius College , Cambridge. The couple went on to have two daughters.
[8]
Career and research
Witten discovered
temporal-difference learning , inventing the tabular TD(0),
[11] the first temporal-difference learning rule for
reinforcement learning . Witten was a co-creator of the
Sequitur algorithm
[12]
and conceived and obtained funding for the development of the original
WEKA software package for
data mining .
[4]
[13]
Witten further made considerable contributions to the field of compression, creating novel algorithms for text and image compression with
Alistair Moffat and
Timothy C. Bell . He is also one of the major contributors to the digital libraries field, and founder of the
Greenstone Digital Library Software .
[14]
His former doctoral students include
Craig Nevill-Manning and
Saul Greenberg .
[2]
Awards and honours
Witten was elected a
ACM Fellow in 1996
[15] and a
Fellow of the
Royal Society of New Zealand (FRSNZ) in 1997.
[16]
In 2004 he received the
International Federation for Information Processing Namur Award for "contributions to the awareness of social implications of information technology, and the need for an holistic approach in the use of information technology that takes account of social implications"
[17] and in 2005 the
Hector Medal for contributions to many areas of computer science.
[18]
Later life and death
Witten retired from the University of Waikato in 2014, and was accorded the title of professor emeritus.
[8] He was diagnosed with cancer in November 2022, and died on 5 May 2023.
