Statistical Estimation from Dependent and Adversarial Data
This thesis studies learning and estimation from data that is not independent, but rather falls into one of the following categories: (1) Data with strong correlations, such as social network correlations and data over a spatial domain or a temporal domain; and (2) Adversarial time series data, …

Sparsity and robustness in modern statistical estimation
… modeling enables the construction of simpler statistical models, with examples including the Lasso and matrix completion. At the same time, statistical models need to be robust--they should perform well when data is noisy--in order to make reliable decisions. While sparsity and robustness are …

Message Passing Algorithms for Statistical Estimation and Communication
This thesis studies two high-dimensional statistical estimation problems: matrix sketching, and communication over many-user channels. Efficient recovery schemes, based on belief propagation (BP) and Approximate Message Passing (AMP), are developed for these problems. We first consider matrix …

Statistical estimation in the presence of group actions
… as Z/p or SO(3). In this thesis we study two statistical models for estimation in the presence of group actions. The first is the synchronization model in which we attempt to learn an unknown collection of group elements based on noisy pairwise comparisons. The second is the orbit recovery …

Statistical estimation and changepoint detection methods in public health surveillance
This thesis focuses on assessing and improving statistical methods implemented in two areas of public health research. The first topic involves estimation of national influenza-associated mortality rates via mathematical modeling. The second topic involves the timely detection of infectious disease …

Statistical estimation problems in phylogenomics and applications in microbial ecology
… genes. Under one common model, species tree estimation is provably statistically consistent by several different methods, but those proofs rely on two separate and potentially shaky assumptions: that every species appears in the data for every gene (i.e., there is no missing data), and that …

A robust optimization approach to statistical estimation problems by Apostolos G. Fertis.
… between robustness and regularization in statistical estimation, for example, in lasso and support vector machines. In the first part of the thesis, we formalize these connections using robust optimization. Specifically (a) We show that in classical regression, regularized estimators like …

Non-intrusive noise measuring on a television picture using spectrum analysis
… is not perfectly flat, a least squares error estimation is made by averaging the high-frequency spectrum points into one noise power estimate. This implies an assumed white noise spectrum. A method to make this noise estimation more robust against high-frequency harmonics, due to structure in …
