evtree: Evolutionary Learning of Globally Optimal Classification and Regression Trees in R

Grubinger, Thomas; Zeileis, Achim; Pfeiffer, Karl-Peter - 2011

Commonly used classification and regression tree methods like the CART algorithm are recursive partitioning methods that build the model in a forward stepwise search. Although this approach is known to be an efficient heuristic, the results of recursive tree methods are only locally optimal, as...

Bayesian and adaptive optimal policy under model uncertainty

Svensson, Lars E. O.; Williams, Noah - 2006

We study the problem of a policymaker who seeks to set policy optimally in an economy where the true economic structure is unobserved, and policymakers optimally learn from their observations of the economy. This is a classic problem of learning and control, variants of which have been studied...

Consistent Estimation of Structural Parameters in Regression Models with Adaptive Learning

Christopeit, Norbert; Massmann, Michael - 2010

In this paper we consider regression models with forecast feedback. Agents' expectations are formed via the recursive estimation of the parameters in an auxiliary model. The learning scheme employed by the agents belongs to the class of stochastic approximation algorithms whose gain sequence is...

Building predictive models for feature selection in genomic mining

Figini, Silvia; Giudici, Paolo - 2006

Building predictive models for genomic mining requires feature selection, as an essential preliminary step to reduce the large number of variable available. Feature selection is a process to select a subset of features which is the most essential for the intended tasks such as classification,...

Competitive targeted marketing

Jo, Hang-Hyun; Kim, Jeong-Yoo - 2012

In this paper, we consider two firms diffusing incompatible technologies and their decision of consumer targeting. The technology adoption is made in two steps. First, once the firms sell their products to their respective targeted consumer, the technology is diffused successively by...

Learning about term structure and optimal rules for inflation targeting

Tesfaselassie, Mewael F.; Schaling, Eric; Eijffinger, … - 2006

In this paper we incorporate the term structure of interest rates in a standard inflation forecast targeting framework. We find that under flexible inflation targeting and uncertainty in the degree of persistence in the economy, allowing for active learning possibilities has effects on the...
