Revealing the Limits of the Source Coding ProblemsNo intellect, no information. The nature of information is digital and discrete. It is invisible, but we can depict it with mathematical science.Each student handles his/her individual research problem.Discussion with the peers is important tosolve it. We must develop partnership and friendship.NishiaraLabCommunication,broadcast,andreadingandwritingonastoragecanberegardedasprocessesofdeliveringinformationfromsourcestodestinations.Inourlab,weformulatethemathematicalmodelsofvariousinformationsystemsandexplorethetheoreticallimitsofthetheirperformance.Forexample,theimplementationofastreamingsystemrequiresaninvestigationoftradeoffbetweenthebandwidthandthecompression.Althoughmanykindsofsuchproductsarealreadyavailableforusage,thetruthbehindthephenomenonisstillnotclear.Atthestartofdigital-broadcasting,emergencysignalsweresenttogetherwithimagedata.However,itturnsoutthatthecompressionprocessofimagedelaysanemergencysignal,andsotheyareprocessedseparatelynow.Byinvestigatingthetradeoffbetweentheprocessingandthedelay,wecanimprovethetransmissionoftheemergencysignals.MikihikoNishiaraAssoc. Prof.is at the present post since 2007 after a research associate of the university of electro-communications. He is interested in information theory. Also has a career as a system engineer.Inourlab,youcandevelopyourprogrammingskillsbecauseyouwillusecomputersimulationsinyourresearch.Youwillalsoearnthetrustofyourcolleaguesasyoutraintoexpressyourunderstandingtoothers.In the FutureAfter GraduationElectrical& Computer EngineeringResearch on Information Technologies from “Image Processing”, “3D Data Processing” to “Evolutionary Multi‐objective Optimization”.Tanaka Lab. has been working on a wide range of information processing technologies, for example, “Image Processing”, “Image Compression” and “Image Classification”, “3D Data Processing” for 3D vector data captured by new measurement devices such as drone, “Data Hiding ” for security of multimedia, interpretation of “Human Visual Perception”, “Multi‐objective Optimization” using “Evolutionary Computation” inspired from the natural evolution of living things, and their applications for creations of innovation. Tanaka lab. has been doing several joint works through collaboration with companies and/or foreign research groups. Prof. Tanaka has accepted a number of foreign students and researchers from different countries in his Lab.“The research on “Evolutionary Multi‐objective Optimization”, which uses “Evolutionary Computation” to solve optimization problems including multiple objective functions has been mainly conducted with French research groups like INRIA, Lille 1 University and Universitédu Littoral Côte d'Opale(ULCO), CINVESTAV in Mexico, and JožefStefan Institute in Slovenia. The researches on “Image Processing” and “Data Hiding” have been conducted with the research groups in University of Malaya and Monash University (offshore campus) in Malaysia. Academic exchange by researchers and students has been actively achieved through the international joint researches. The alumni of our laboratory are currently working as researchers and development engineers at manufacturing companies in wide range of areas such as electrical, electricity, communication, information processing, machinery, electric device and medical system. Some of them are faculty members in universities including Shinshu University.Professor Kiyoshi TanakaProf. Tanaka has worked at Shinshu University since 1997. Currently, he is the Vice‐President of Shinshu University in charge of international affairs, as well as the director of Global Education Center.He has put great effort into global education and international academic exchange with universities and research centers abroad.Shinshu Univ. has signed the agreement for academic cooperation and exchange with INRIA, which is the most prestigious research institute in France. (From the left, 1st: Dr. Marc Schoenauer, 3rd: Prof. Tanaka, 5th: Dr. Michel Cosnard, Chairman and CEO of INRIA) TanakaLabIn the FutureAfter GraduationThe concept of problem‐solving using Evolutionary Computation for large scale/many‐objective optimization problem; derivation of the set of optimal solutions in the management and the operation of complicated system.Electrical& Computer Engineering26
