A new auxiliary function method for general constrained global optimization
Optimization, 2013 In this article, we first propose a method to obtain an approximate feasible point for general constrained global optimization problems (with both inequality and equality constraints). Then we propose an auxiliary function method to obtain a global minimizer or an approximate global minimizer with a required precision for general global optimization ...

Solving nonlinearly constrained global optimization problem via an auxiliary function method
Journal of Computational and Applied Mathematics, 2009 Constrained continuous global minimization problems can be converted to unconstrained ones by adding a penalty term to the objective function. Penalty function methods require usually the determination of parameters, so that constrained and unconstrained problems have global minimizers.

Efficient Computations of a Security Index for False Data Attacks in Power Networks [PDF]
, 2013 The resilience of Supervisory Control and Data Acquisition (SCADA) systems for electric power networks for certain cyber-attacks is considered. We analyze the vulnerability of the measurement system to false data attack on communicated measurements.

New approximate-analytical solutions to partial differential equations via auxiliary function method
Partial Differential Equations in Applied Mathematics, 2021 In this article, the optimal auxiliary function method (OAFM) is extended to general partial differential equations (PDEs). Our proposed method is highly efficient and provides the means of controlling the approximate solution’s convergence. Illustrative

Multi-Task Transformer with Adaptive Cross-Entropy Loss for Multi-Dialect Speech Recognition
Entropy, 2022 At present, most multi-dialect speech recognition models are based on a hard-parameter-sharing multi-task structure, which makes it difficult to reveal how one task contributes to others.

Hashing with binary autoencoders
, 2015 An attractive approach for fast search in image databases is binary hashing, where each high-dimensional, real-valued image is mapped onto a low-dimensional, binary vector and the search is done in this binary space.
