Data mining and business analytics with big and small data
- it is not always size that matters

Abstract: Will review useful methods for data mining
and business analytics describing several applications
and case studies where these methods have proven
useful. Also will discuss the importance of collecting
one's own data through carefully designed statistical

Data Mining with Bayesian Trees

Abstract: Tree regression and classification modeling play a
fundamental role in data mining. In addition to being an important
method in their own right, trees are often used in ensemble methods
such as bagging and boosting in which high dimensional models are
built up from many trees. In this talk, we review practical Bayesian
approaches to data mining with trees and illustrate simple, easy to
use, software implementations which are available in R.

Fitting trees to data presents interesting challenges. There are many
possible tree structures so that searching the tree space for an
appropriate model is challenging. Bayesian inferential methods have
much to offer. The prior specification allows for parsimonious
regularization of the fit as well as nonparametric model
specification. Markov chain Monte Carlo provides a framework for
specifying stochastic searches in this vast model space. Recent
advances in parallel computing have made these Bayesian approaches
practical for large data sets.
