报告一： Discovering Interesting Exception Rules with Rule Pair 报告人： Professor Einoshin Suzuki 时间地点： 10月24日，14:30-15:30, 蒙民伟楼404会议室 Abstract: In this talk, I would like to talk about our endeavor for discoverin
g interesting exception rules with the rule pair as the pattern representation
. Rule discovery in data mining is prone to output a huge number of rules, mos
t of which are uninteresting. In 1996, to circumvent the problem, I proposed a
pattern representation which corresponds to a pair of a general rule and its
exception rule. Interestingly, the representation captures a kind of interesti
ngness through its form and a manageable number of patterns are discovered des
pite of its large number of freedom. I will especially talk about how to deriv
e an analytical solution to distinguish patterns from noise, pruning technique
s to keep the computational time practical, and validation with a medical data
set in which a physician is involved in evaluating patterns produced by a pur
ely objective method. 报告二： Mining Chronic Hepatitis Data in Active Mining Project 报告人： Professor Einoshin Suzuki 时间地点： 10月25日，14:30-15:30, 蒙民伟楼404会议室 Abstract: In this talk, I would like to talk about our endeavor for mining chr
onic hepatitis data in the active mining project, which was funded by MEXT, Ja
pan. The project, headed by Prof. Motoda, lasted 4 years and I served as one t
he 10 representatives. The data were provided by Chiba University Hospital and
posed us various challenges including setting the objective of the analysis.
We began by proposing time-series decision tree for liver cirrhosis prediction
then developed PrototypeLines for visualizing medical tests of a patient. Fin
ally, our spiral exception discovery approach revealed interesting findings wi
th the help of physicians and automatically re-discovered a tendency which had
been reported in a medical journal. 简历： Einoshin Suzuki received his degrees from the University of Tokyo in 19
88 (Bachelor of Engineering), in 1990 (Master of Engineering), and in 1993 (Do
ctor of Engineering). He joined Tokyo Institute of Technology as an assistant
professor in 1993 then Yokohama National University as a lecturer Professor in
1996. He has served as an associate professor in Yokohama National University
from 1997 to 2006 and he is with Kyushu University as a full professor since
2006. He has been the Steering Committee Chair of the International Conference
s on Discovery Science since 2005. He has served as a Chair of more than 10 in
ternational conferences including ICDM: the IEEE Data Mining Conference (Works
hops Chair in 2002, PC Vice Chair in 2004, and Sponsorship Chair in 2006). He
has served as an evaluating expert of INRIA Cog A Projects in 2007 and an eval
uation committee member of the Information Grand Voyage project, which is supp
orted by METI, Japan, in 2008. Professor Einoshin Suzuki’s homepage: http://www.i.kyushu-u.ac.jp/~suzuki/ |
