Optimal Minimization of the Covariance Loss

open access: yesIEEE Transactions on Information Theory, 2023
Let $X$ be a random vector valued in $\mathbb{R}^{m}$ such that $\|X\|_{2} \le 1$ almost surely. For every $k\ge 3$, we show that there exists a sigma algebra $\mathcal{F}$ generated by a partition of $\mathbb{R}^{m}$ into $k$ sets such that \[\|\operatorname{Cov}(X) - \operatorname{Cov}(\mathbb{E}[X\mid\mathcal{F}]) \|_{\mathrm{F}} \lesssim \frac{1 ...

STCMH with minimal semantic loss [PDF]

open access: yesIET Image Processing, 2019
Cross‐modal hashing (CMH) has received widespread attention due to high retrieval efficiency, which plays an extremely important role in cross‐modal retrieval. Recently, many CMH methods have been proposed to establish the semantic connection of different modalities.

Analytic Loss Minimization: A Proof [PDF]

open access: yesIEEE Transactions on Power Systems, 2016
Abstract—Loss minimizing generator dispatch profiles for power systems are usually derived using optimization techniques. However, some authors have noted that a system’s KGL matrix can be used to analytically determine a loss minimizing dispatch. This letter draws on recent research on the characterization of transmission system losses to demonstrate ...

Loss minimization in parse reranking [PDF]

open access: yesProceedings of the 2006 Conference on Empirical Methods in Natural Language Processing - EMNLP '06, 2006
We propose a general method for reranker construction which targets choosing the candidate with the least expected loss, rather than the most probable candidate. Different approaches to expected loss approximation are considered, including estimating from the probabilistic model used to generate the candidates, estimating from a discriminative model ...

On Data Preconditioning for Regularized Loss Minimization [PDF]

open access: yesMachine Learning, 2015
In this work, we study data preconditioning, a well-known and long-existing technique, for boosting the convergence of first-order methods for regularized loss minimization. It is well understood that the condition number of the problem, i.e., the ratio of the Lipschitz constant to the strong convexity modulus, has a harsh effect on the convergence of ...

A Comprehensive Review of Metaheuristic Methods for the Reconfiguration of Electric Power Distribution Systems and Comparison With a Novel Approach Based on Efficient Genetic Algorithm

open access: yesIEEE Access, 2021
The distribution system reconfiguration (DSR) is a complex large-scale optimization problem, which is usually formulated with one or more objective functions and should satisfy multiple sets of linear and non-linear constraints.

Core loss resistance impact on sensorless speed control of an induction motor using hybrid adaptive sliding mode observer [PDF]

open access: yesArchives of Electrical Engineering, 2023
Induction motors (IMs) experience power losses when a portion of the input power is converted to heat instead of driving the load. The combined effect of copper losses, core losses, and mechanical losses results in IM power losses.

Making Risk Minimization Tolerant to Label Noise [PDF]

open access: yes, 2015
In many applications, the training data, from which one needs to learn a classifier, is corrupted with label noise. Many standard algorithms such as SVM perform poorly in presence of label noise.
