Robustness of Consistent Loss Functions for Multinomial Outcome Models
… estimation, which uses the logarithmic loss function, is the default method used to estimate latent parameters consistently in multinomial outcome models. However, it is sensitive to even a tiny fraction of corruption in the training data. Alternatively, other loss functions in the …

Robust MEWMA-type Control Charts for Monitoring the Covariance Matrix of Multivariate Processes
… distributions. Additionally, the total extra quadratic loss is proposed to evaluate the overall performance of control charts for multivariate processes.

High-order tuners for convex optimization : stability and accelerated learning
… for a linear regression framework producing a quadratic loss function. This thesis extends and discuss the results of this same HT for general smooth convex loss functions. Through the exploitation of convexity and smoothness definitions, we establish similar stability and asymptotic …

Simultaneous Design of Communication Strategies and Control Policies in Stochastic Systems
… classes of such problems with linear dynamics, quadratic loss functionals and Gaussian statistics for which the optimality of linear strategies can be established. The general approach used consists of first finding a lower bond on the cost, and then constructing joint strategies that attain …

Contributions to quality improvement methodologies and computer experiments
… design optimization is often based on average quadratic loss computed as if the posterior mean were the true response function, which can give misleading results. We propose optimization criteria derived by taking expectation of the average quadratic loss with respect to the posterior …

Trait-based approaches to marine microbial ecology
… taxonomy was found, suggesting that growth and loss processes nearly balance across a range of cell sizes and between diatoms and dinoflagellates. In Chapter 3, I examined a global ocean circulation, biogeochemistry, and ecosystem model that indicated a decrease in) phytoplankton diversity with …

Algorithms and Theory for Robust PCA and Phase Retrieval
… the median truncation approach to the Poisson loss and the reshaped quadratic loss respectively, and obtain two algorithms \emph{median-TWF} and \emph{median-RWF}. We show that both algorithms recover the signal from a near-optimal number of independent Gaussian measurements, even when a …

Kinetic modeling and automated optimization in microreactor systems
… A further optimization is performed using a quadratic loss function to penalize conversions of less than 85%. This optimization of production rate led to an optimum at higher residence time, where a conversion of 81% is achieved. In the conventional view of reaction analysis, batch reactions …
