"Association Rule Analysis"
ABSTRACT: We will discuss some topics from Chapter 14
of the HTF book. Specifically, the topic on association rule
analysis will be discussed in details. An association rule, in
context of sales transactions, is a subset of commercial
items which are purchased together frequently by customers.
How to mine an association rule from a large collection of
items (imagine Wal-Mart or Meijer's sales transactions for
example) can be very challenging statistically and
computationally. Association rule analysis, as an unsupervised
learning procedure, has emerged as a popular tool for mining
commercial data bases. The Apriori algorithm to seek association
rules is one of the major advances in data mining technology.
How to transform the unsupervised learning problem to an
supervised learning problem will also be discussed.

"On polynomial approximation...with a complex"
ABSTRACT: Some elementary answers to the following question
will be given: When is it possible to approximate a real-valued
function by polynomials? In an attempt to understand some of our
answers, we will be lead very rapidly to the introduction of complex
numbers. It will then become natural to consider the problem of
approximating a function of a complex variable by polynomials.

"Uniform approximation on Riemann surfaces: a survey"
ABSTRACT: The qualitative theory of uniform approximation by
holomorphic (think: polynomial) or meromorphic (think: rational)
functions on compact subsets of Riemann surfaces is relatively well-
understood. We have now complete characterizations of those
compacts sets on which approximation is always possible. When
replacing compact sets by closed but not necessarily bounded sets,
very little is known, except in the planar case. I intend to present a
survey of the theory, including recent results and open problems.
