Statistical enhancement of support vector machines

Creator:

Taylor, Aimee E.

Abstract:

Support Vector Machines (SVM) and Random Forests (RF) have consistently outperformed other machine learning algorithms on a variety of problems. SVM can be used for classification and regression on many types of data (e.g. nonlinear, high dimensional), but cannot handle missing or mixed data. This research implements a permutation-based variable...

Optimizing spatial and temporal aspects of nature reserve design under economic and ecological objectives

Creator:

Nalle, Darek J.

Abstract:

Alteration of natural areas in attempts to support increasing human populations has been a crucial yet less publicized contributor to the fall of many of the world's greatest civilizations, since healthy ecosystems can help maintain stable societies and economies. Given this unhappy fact and the ancient relationship between people and...

Spatially explicit inter-temporal forest management decision under the risk of fire

Creator:

Konoshima, Masashi

Abstract:

This paper presents a framework for analyzing efficient spatial allocation of forest management efforts - fuel treatment and harvest - under the risk of fire. The framework integrates a fire behavior model and a spatially-explicit stochastic dynamic optimization model. I investigate the effects of spatial interaction across plots during forest...
