A Bayesian Approach to Graphical Record Linkage and Deduplication
(Journal of the American Statistical Association, 2016-10-01)© 2016 American Statistical Association.We propose an unsupervised approach for linking records across arbitrarily many files, while simultaneously detecting duplicate records within files. Our key innovation involves the ... -
A branching process model for flow cytometry and budding index measurements in cell synchrony experiments.
(Ann Appl Stat, 2009)We present a flexible branching process model for cell population dynamics in synchrony/time-series experiments used to study important cellular processes. Its formulation is constructive, based on an accounting of the unique ... -
A Cheeger-type inequality on simplicial complexes
(ADVANCES IN APPLIED MATHEMATICS, 2014-05) -
A Digital Network Approach to Infer Sex Behavior in Emerging HIV Epidemics
(PLOS ONE, 2014-07-03) -
A framework for integrating the songbird brain.
(J Comp Physiol A Neuroethol Sens Neural Behav Physiol, 2002-12)Biological systems by default involve complex components with complex relationships. To decipher how biological systems work, we assume that one needs to integrate information over multiple levels of complexity. The songbird ... -
A nucleosome-guided map of transcription factor binding sites in yeast.
(PLoS Comput Biol, 2007-11)Finding functional DNA binding sites of transcription factors (TFs) throughout the genome is a crucial step in understanding transcriptional regulation. Unfortunately, these binding sites are typically short and degenerate, ... -
A phylogenetic transform enhances analysis of compositional microbiota data.
(Elife, 2017-02-15)Surveys of microbial communities (microbiota), typically measured as relative abundance of species, have illustrated the importance of these communities in human health and disease. Yet, statistical artifacts commonly plague ... -
A Quantitative Approach to Predict Differential Effects of Anti-VEGF Treatment on Diffuse and Focal Leakage in Patients with Diabetic Macular Edema: A Pilot Study.
(Translational vision science & technology, 2017-03-21)We use semiautomated segmentation of fluorescein angiography (FA) to determine whether anti-vascular endothelial growth factor (VEGF) treatment for diabetic macular edema (DME) differentially affects microaneurysm (MA)-associated ... -
A Spatio-temporal Coupling Method to Reduce the Time-to-Solution of Cardiovascular Simulations
(http://ieeexplore.ieee.org/abstract/document/6877292/, 2017-01-28)We present a new parallel-in-time method designed to reduce the overall time-to-solution of a patient-specific cardiovascular flow simulation. Using a modified Para real algorithm, our approach extends strong scalability ... -
Advances to Bayesian network inference for generating causal networks from observational biological data.
(Bioinformatics, 2004-12-12)MOTIVATION: Network inference algorithms are powerful computational tools for identifying putative causal interactions among variables from observational data. Bayesian network inference algorithms hold particular promise ... -
Analysis and Observations From the First Amazon Picking Challenge

Architectural implications of nanoscale-integrated sensing and computing
(IEEE Micro, 2010-01-01)The authors explore nanoscale sensor processor (nSP) architectures. Their design includes a simple accumulator-based instruction-set architecture, sensors, limited memory, and instruction-fused sensing. Using nSP technology ... -
Attack-resilient sensor fusion for safety-critical cyber-physical systems
(ACM Transactions on Embedded Computing Systems, 2016-02-01)© 2016 ACM.This article focuses on the design of safe and attack-resilient Cyber-Physical Systems (CPS) equipped with multiple sensors measuring the same physical variable. A malicious attacker may be able to disrupt system ... -
Attack-Resilient State Estimation in the Presence of Noise
We consider the problem of attack-resilient state estimation in the presence of noise. We focus on the most general model for sensor attacks where {any} signal can be injected via the compromised sensors. An $l_0$-based ... -
Automatic segmentation of seven retinal layers in SDOCT images congruent with expert manual segmentation.
(Opt Express, 2010-08-30)Segmentation of anatomical and pathological structures in ophthalmic images is crucial for the diagnosis and study of ocular diseases. However, manual segmentation is often a time-consuming and subjective process. This paper ... -
Automatic verification of linear controller software
(2015 Proceedings of the International Conference on Embedded Software, EMSOFT 2015, 2015-11-04)© 2015 IEEE.We consider the problem of verification of software implementations of linear time-invariant controllers. Commonly, different implementations use different representations of the controller's state, for example ... -
BAYESIAN MODEL SEARCH AND MULTILEVEL INFERENCE FOR SNP ASSOCIATION STUDIES.
(Ann Appl Stat, 2010-09-01)Technological advances in genotyping have given rise to hypothesis-based association studies of increasing scope. As a result, the scientific hypotheses addressed by these studies have become more complex and more difficult ... -
BOLT: Energy-efficient out-of-order latency-tolerant execution
(Proceedings - International Symposium on High-Performance Computer Architecture, 2010-05-27)LT (latency tolerant) execution is an attractive candidate technique for future out-of-order cores. LT defers the forward slices of LLC (last-level cache) misses to a slice buffer and re-executes them when the misses return. ... -
Citizen Science as a New Tool in Dog Cognition Research.
(PLoS One, 2015)Family dogs and dog owners offer a potentially powerful way to conduct citizen science to answer questions about animal behavior that are difficult to answer with more conventional approaches. Here we evaluate the quality ... -
Communications inspired linear discriminant analysis
(Proceedings of the 29th International Conference on Machine Learning, ICML 2012, 2012-10-10)We study the problem of supervised linear dimensionality reduction, taking an information-theoretic viewpoint. The linear projection matrix is designed by maximizing the mutual information between the projected signal and ...
