Binary Regression Quantiles
… optimization problems that requires the use of a global optimizer. Chapter 5 reviews some of the literature on simulated annealing, a method widely used in a diverse array of fields to solve demanding optimization problems.

Algorithms and Theory for Robust PCA and Phase Retrieval
… in such a way that the true vector is its global optimizer, the difficulty here is to design algorithms to find the global optimizer efficiently and provably. </p> <p> In order to solve this problem, we propose a gradient-like algorithm named reshaped Wirtinger flow (RWF). For random …

The Diffusion Equation Method for Global Optimization and Its Application to Magnetotelluric Geoprospecting
… use of the Diffusion Equation Method (DEM) for global optimization in implementing an approximate quasisolution method for determining the size, shape, and orientation of an underground deposit. We examine the theoretical underpinnings of the DEM, first discussing the concepts of smoothing and …

Minimum-correction second-moment matching : theory, algorithms and applications
… . We obtain a closed-form formula for the unique global optimizer Ũ for the full-rank case, which is related to U by an SPD (symmetric positive definite) linear transform. This result is generalized to rank-deficient cases as well as to infinite dimensions. We highlight the geometric intuition …

Global Optimization of MGA-DSM Problems Using the Interplanetary Gravity Assist Trajectory Optimizer (IGATO)
… first part of this work explores the realm of global optimization applied to multiple gravity assist trajectories with deep space maneuvers (MGA-DSM). With the constant influx of new global optimization algorithms and heuristics being developed in the global optimization community, this work …

Learning in the Multi-Robot Pursuit Evasion Game
… QFIS algorithm. The PSO algorithm is used as a global optimizer, whereas the QFIS algorithm is used as a local optimizer. The second one is a modified version of the fuzzy-actor critic learning (FACL) algorithm, which is called fuzzy actor-critic learning Automaton (FACLA) algorithm. It uses the …

GNN-Enhanced Hierarchical Federated Learning in Device-to-Device Networks
… dynamic network topologies, which can compromise global model convergence and training stability. Moreover, the growing complexity and diversity of edge intelligence tasks further motivate the development of collaborative strategies for efficiently fine-tuning large foundation models within the …

Methods for Accurately Modeling Complex Materials
… of the computational cost. We also present a new global optimization procedure that we have implemented for computationally demanding classical potential fits.

Consistent community detection in uni-layer and multi-layer networks
… investigate the consistency properties of the global optimizer of the objective functions under the multi-layer stochastic block model. We derive several new asymptotic results showing consistency of the intermediate fusion techniques along with the spectral clustering of mean adjacency matrix …

A Multiplexed, Multi-scale Optical Imaging Platform to Quantify Tumor Metabolic Heterogeneity
… cancerous from benign lesions. The Center for Global Women’s Health Technologies (GWHT) has employed the use of exogenous fluorescent contrast agents to provide substrate-specific metabolic information. Three fluorescent agents have been validated including: 2-[N-(7-nitrobenz-2-oxa-1, …
