Priya worked with Drs. Peter Hammer and Ilya Muchnik, both of the
Rutgers Center
for Operations Research, as part of a team working on a long-term
project in prediction based on performance patterns. To quote from
her research report: "The work I did with RUTCOR this summer was not
individual work, but work as part of a team. This was a great
experience, not only because I learned a lot from the professors of
RUTCOR, but also because it allowed me to be part of a project that
had already begun years before I came here, and thus made me part of a
team that was constantly looking for better results, new ways of
analyzing the results, clear goals and purposes for their projects
and challenging new studies that would be useful in answering real
world questions. Working here at RUTCOR has definitely made me
interested in pursuing a career in Operations Research."
The method of Logical Analysis of Data (LAD) provides techniques to
identify various regularities in data; in particular, to predict some
binary attribute on the basis of other attributes that may
be continuous. Whereas all previous applications of LAD have been to
reveal a cause-effect relationship, the objective of this work was to
attempt to predict the future state of an attribute given the history
of the states of a set of
causal attributes. For this purpose, LAD has been applied to the
Chinese Economy database -- the database on the marketization process
in the industrial sector of the People's Republic of China. Twelve
attributes had been observed in 29 provinces of China over 10 years
from 1985 to 1994. Using this data they analyzed the ability of LAD
to (1) predict labor productivity and (2) measure the importance of, and
monotonicity trends of attributes in the prediction of labor
productivity. Priya and Dr. Hammer are preparing a paper describing
this research.
