Subhash Kak (born March 26, 1947 in Srinagar) is an Indian American computer scientist. He is Regents Professor and a previous Head of Computer Science Department at Oklahoma State University–Stillwater who has made contributions to cryptography, artificial neural networks, and quantum information. Kak is also notable for his Indological publications on the history of science, the philosophy of science, ancient astronomy, and the history of mathematics.〔Usha Akella's feature: http://www.thehindu.com/features/magazine/the-renaissance-man/article5478590.ece〕 Alan Sokal labeled Kak "one of the leading intellectual luminaries of the Hindu-nationalist diaspora." His brother is the computer scientist Avinash Kak.〔Kak, Ram Nath. Autumn Leaves. Vitasta, 1995.〕 ==Life== Subhash Kak completed his BE from NIT Srinagar and Ph.D. at the Indian Institute of Technology Delhi in 1970. He taught there. During 1975-1976, he was a visiting faculty at Imperial College, London, and a guest researcher at Bell Laboratories, Murray Hill. In 1977, he was a visiting researcher at Tata Institute of Fundamental Research, Bombay.〔http://www.ece.okstate.edu/sites/default/files/biography.pdf〕 In 1979 joined Louisiana State University, Baton Rouge, where he was the Donald C. and Elaine T. Delaune Distinguished Professor of Electrical and Computer Engineering. In 2007, he joined the Computer Science department at Oklahoma State University–Stillwater.〔()〕 His research is in the fields of cryptography, random sequences, artificial intelligence, quantum mechanics, and information theory. He proposed a test of algorithmic randomness〔(Terry Ritter, Randomness tests )〕 and a type of instantaneously trained neural networks (INNs) (which he and his students have called "CC4 network" and others have called "Kak neural networks"). He was the first to formulate the discrete and the number theoretic Hilbert transforms.〔Kak, S. The discrete Hilbert transform. Proc. IEEE, vol. 58, pp. 585-586, April 1970.〕〔Kak, S.The number theoretic Hilbert transform. Circuits, Systems and Signal Processing, vol. 33, pp. 2539-2548, 2014.〕 He claims to be amongst the first to apply information metrics to quantum systems.〔Kak, S. "On quantum numbers and uncertainty," ''Nuovo Cimento'', 34B, 530-534, 1976.〕〔Kak, S. On information associated with an object. Proceedings Indian National Science Academy, vol. 50, pp. 386-396, 1984.〕 He was featured as one of the pioneers of quantum learning in the journal Neuroquantology edited by Cheryl Fricasso and Stanley Krippner.〔()〕 He is featured as one of the interviewees in the area of mathematics and information in the long-standing PBS series Closer to Truth.〔http://www.closertotruth.com/contributors/mathematics-information〕 Kak proposed a fast matrix multiplication algorithm for cross-wired meshes.〔Kak, S. A two-layered mesh array for matrix multiplication. Parallel Computing, vol. 6, pp. 383-385, 1988.〕 He proposed the use of repeating decimals and other random sequences for error correction coding and cryptography.〔Kak, S. Encryption and error-correction coding using D sequences. ''IEEE Transactions on Computers'', C-34: 803-809, 1985. (Watermarking using decimal sequences )〕〔Kak, S. Goldbach partitions and sequences. Resonance, vol. 19, pp. 1028-1037, November 2014.〕 In cryptography, he has advanced new methods of secret sharing that are of importance in distributed systems such as wireless and sensor networks.〔Parakh, A. and S. Kak, Online data storage using implicit security. Information Sciences, vol. 179, pp. 3323-3331, 2009.〕〔Parakh, A. and S. Kak, Space efficient secret sharing for implicit data security. Information Sciences, vol. 181, pp. 335-341, 2011.〕 Kak has argued that there are limits to the intelligence machines can have and it cannot equal biological intelligence.〔Kak, S. Active agents, intelligence and quantum computing. Information Sciences, vol. 128, 1-17, 2000.〕 He asserts that: :"...machines fall short on two counts as compared to brains. Firstly, unlike brains, machines do not self-organize in a recursive manner. Secondly, machines are based on classical logic, whereas Nature's intelligence may depend on quantum mechanics." :"(), if machines with consciousness are created, they would be living machines, that is, variations on life forms as we know them. Second, the material world is not causally closed, and consciousness influences its evolution. Matter and minds complement each other."〔Kak, S. Artificial and biological intelligence. ''ACM Ubiquity'', Volume 6, Issue 42, 2005.()〕 He is also the author of several books of poems.〔Elliott, M. http://statemagazine.org/subhash_kak〕〔http://www.museindia.com/featurecontent.asp?issid=53&id=4688〕〔Akella, U. http://www.museindia.com/featurecontent.asp?issid=53&id=4686〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Subhash Kak」の詳細全文を読む スポンサード リンク
