3 - Discriminating Parkinson’s Disease (pd) Using Functional
Connectivity And Brain Network Analysis
Shouyi Wang, University of Texas at Arlington,
shouyiw@uta.eduIn this study, we explored the use of functional connectivity patterns in fMRI data
to classify subjects on the basis of Parkinson’s disease. We explore various brain
networks and features. We partition our fMRI data in 5 filtered frequency ranges.
We use a proximal support vector machine paired with a minimum-redundancy
and maximum-relevance feature selection method on each frequency range. We
use a majority voting ensemble classification method on the results of the
proximal support vector machine classification results. Our results indicate that
the ensemble method is effective compared to a single broad frequency range,
and that Bonferroni correction may enhance classification results.

Reduce Overdiagnosis

Although the early diagnosis of breast cancer through screening mammography
saves thousands of lives every year, overdiagnosis of breast cancer may cause
harm without benefit. We propose a comprehensive large-scale optimization
model to address overdiagnosis by making better-informed diagnostic decisions
and provide the exact optimal policies that potentially save up to 9% of the
biopsied population from overdiagnosis..
2 - A Decision Support System for the Management of Aid-In-Kind

Turkish Red Crescent is the main body for collection and distribution of donations
in Turkey, and this project aims to improve their donation collection and
distribution processes by proposing a decision support system with numerous
subsystems; e.g. implementing new process flows and their accompanying
decisions. The proposed system is approved by TRC and it is being integrated to
their systems.

We develop a two-stage stochastic model to optimally place green roofs and/or
Photovoltaic panels under climate change uncertainty, with the aim of improving
urban system resilience. Different climate forecasts from different climate models
are taken into account as different scenarios. The interaction between green roofs
and Photovoltaic panels in terms of efficiency is considered. An efficient L-shaped
algorithm is developed. Computational studies along with sensitivity analysis are
conducted.

Green Infrastructures (GIs) are low cost, low regret strategies that can
dramatically contribute to stormwater management. We develop a multi-objective
stochastic programming model to determine the optimal placement of GIs across a
set of candidate locations in a watershed to minimize the excess runoff under
short-term and medium-term precipitation uncertainties. We calibrate the model
using precipitation projections and stormwater system’s hydrologic responses to
them. We obtain the optimal GI placement for a watershed and perform
sensitivity and robustness analyses to provide insights.

Despite the environmental and societal benefits of Green Infrastructure (GI), they
are mostly planned and established in response to an existing problem rather than
being actively incorporated into the early stages of urban planning. In this paper,
we present a stochastic model that would allow urban planners to incorporate
uncertainties in population and climate predictions, land use and budgetary
constraints and the ‘connectivity’ between GIs into the decision making process of
GI placement on a county or city scale land area. The proposed approach is tested
on data from a real county to evaluate its utility.

xi-wang-1@uiowa.edu1 - Link Prediction In Multi-relational Networks For Online
Health Communities
Xi Wang, The University of Iowa,

Online Health Communities (OHCs) are a popular resource for those with health
problems to exchange information and support. Users often interact via multiple
communication channels, such as online discussions, blogs, and private messages.
Connections among users via different channels form a multi-relational social
network. Using data from a smoking cessation network, this study aims to predict
links between users in one sub-network based on information from other sub-
networks. Our findings regarding tie formation will inform the development and
ongoing management of online health communities.
