Appropriate technology water treatment processes for MaeLa Temporary Shelter, Thailand
(Massachusetts Institute of Technology, 2008)This thesis recommends the use of horizontal-flow roughing filters to treat spring water of variable annual quality in MaeLa Temporary Shelter, Thailand. The public drinking water system for 45,000 refugees is overseen by ... -
Appropriate water treatment for the Nyanza Province of Kenya
(Massachusetts Institute of Technology, 2005)In 2000 the Centers for Disease Control and Prevention (CDC) in conjunction with CARE International began working with several local non-governmental organizations (NGOs) in the Nyanza Province of Kenya to reduce the rate ... -
Appropriateness and feasibility of targeted diversification in a private equity portfolio
(Massachusetts Institute of Technology, 2006)Diversification tools such as modem portfolio theory are used by institutional investors when making asset allocation decisions, which often result in an allocation to the private equity asset class. While some level of ... -
Approximate Bayesian Modeling with Embedded Gaussian Processes
(Massachusetts Institute of Technology, 2023-09)Bayesian inference plays an important role in uncertainty quantification and decision making in science and engineering applications. However, the presence of complex model components can significantly impact model accuracy ... -
Approximate cross validation for sparse generalized linear models
(Massachusetts Institute of Technology, 2019)Cross validation (CV) is an effective yet computationally expensive tool for assessing the out of sample error for many methods in machine learning and statistics. Previous work has shown that methods to approximate CV can ... -
An approximate dynamic programming approach to discrete optimization
(Massachusetts Institute of Technology, 2000)We develop Approximate Dynamic Programming (ADP) methods to integer programming problems. We describe and investigate parametric, nonparametric and base-heuristic learning approaches to approximate the value function in ... -
An approximate dynamic programming approach to risk sensitive control of execution costs
(Massachusetts Institute of Technology, 2009)We study the problem of optimal execution within a dynamic programming framework. Given an exponential objective function, system variables which are normally distributed, and linear market dynamics, we derive a closed ... -

Approximate dynamic programming with applications in multi-agent systems
(Massachusetts Institute of Technology, 2007)This thesis presents the development and implementation of approximate dynamic programming methods used to manage multi-agent systems. The purpose of this thesis is to develop an architectural framework and theoretical ... -
Approximate inference : decomposition methods with applications to networks
(Massachusetts Institute of Technology, 2009)Markov random field (MRF) model provides an elegant probabilistic framework to formulate inter-dependency between a large number of random variables. In this thesis, we present a new approximation algorithm for computing ... -
Approximate inference in Gaussian graphical models
(Massachusetts Institute of Technology, 2008)The focus of this thesis is approximate inference in Gaussian graphical models. A graphical model is a family of probability distributions in which the structure of interactions among the random variables is captured by a ... -
Approximate inference in graphical models using LP relaxations
(Massachusetts Institute of Technology, 2010)Graphical models such as Markov random fields have been successfully applied to a wide variety of fields, from computer vision and natural language processing, to computational biology. Exact probabilistic inference is ... -
Approximate inference methods for grid-structured MRFs
(Massachusetts Institute of Technology, 2004)In this thesis, I compared the mean field, belief propagation, and graph cuts methods for performing approximate inference on an MRF. I developed a method by which the memory requirements for belief propagation could be ... -
