A Sequential Hypothesis Testing Approach to Detecting Small, Moving Objects in Image Sequences
… at each pixel in the sequence and tested sequentially for a shift in mean intensity. Underlying the algorithm are new general results in detection theory, including the use of multistage hypothesis testing (MHT) for simultaneous inference, and a new framework for quickest detection of …

Applications of sequential hypothesis testing to the development of non-invasive brain-computer interfaces
Sequential hypothesis testing is applied in this thesis to make two contributions to the classification of electroencephalography (EEG) data for use in non-invasive brain computer interfaces (BCIs). The first contribution is a variable window-length classification method for use in a steady-state …

Change Point Detection in Time Series via Multivariate Singular Spectrum Analysis
… with the cumulative sum (CUSUM) procedure for sequential hypothesis testing. In particular, we model the underlying dynamics of multivariate time series observations through the spatio-temporal model introduced recently in the mSSA literature. The change points in such a setting correspond to a …

Quickest change detection with applications to line outage detection
… We start by discussing fundamental results of sequential hypothesis testing and QCD, and by proposing an algorithm for the QCD setting under transient dynamics. Following, we apply these results in the line outage detection problem. QCD algorithms are applied on measurements of voltage phase …

Rogue Access Point Detection through Statistical Analysis
… wired and wireless TCP traffic using Weighted Sequential Hypothesis Testing on inter-arrival time of TCP ACK-pairs. A decentralized module takes care of detection of MAC spoofing and totally relies on 802.11 beacon frames. Detection is done through analysis of the clock skew and the Received …

Problems in GPS Accuracy
… positioning. Linear regression models and sequential hypothesis testing are used to model, detect, and repair cycle-slips. The effectiveness of these methods is studied using data obtained from ground-station receivers.</p>

A robustness type optimality criterion for experimental design
… of the existing stopping rules. It is based on a sequential hypothesis testing controlled by two stopping bounds. These bounds are determined so that the efficiency of the procedure is maximized.

Variational approximation for importance sampling and statistical inference on social influence
… the performance of importance sampling and sequential importance sampling. In the second part of the thesis, we propose a sequential hypothesis testing procedure to detect the degrees of influence in a network. We build a multivariate Bernoulli model to represent the status of each node in …
