Identification of Client Profile Using Convolutional Neural Networkske a multi-class image classification to target social networks users as potential products consumers. In this paper, we compare the performance of several artificial neural network training algorithms using adaptive learning: stochastic gradient descent, adaptive gradient descent, adaptive moment e

GPU-Based Criticality Analysis Applied to Power System State Estimationinate spurious measurements. SE requires an adequate number of measurements, varied, and strategically distributed in the power grid. Criticality analysis consists of identifying which combinations of measurements, forming tuples of different cardinalities, are essential for observing the power netw

Robust Control of the Classic Dynamic Ball and Beam Systemontrol techniques. Two controllers were designed based on Algebraic Riccati Equations for the synthesis of . and . controllers and a third one based on Linear Matrix Inequalities techniques for the design of . controllers. The results show that . controllers offer better performance.

Impact of OVL Variation on AUC Bias Estimated by Non-parametric Methodses between two mutually exclusive conditions. The AUC can admit values between 0.5 and 1, where values close to 1 indicate that the model of classification has a high discriminative power. The overlap coefficient (OVL) between two density functions is defined as the common area between both function

Adjusting ROC Curve for Covariates with AROC R Packagelysis for reliability and improvement. The receiver operating characteristic (ROC) curve remains a popular method of marker analysis, disease screening and diagnosis. Covariates in this field related to the subject’s characteristics are incorporated in the analysis to avoid bias. The covariate adjus

GPU-Based Criticality Analysis Applied to Power System State Estimationugh multi-threads execution on CPU and GPU environments. To date, no publication reporting the use of GPU for computing critical elements of the SE process is found in the specialized literature. Numerical results from simulations performed on the IEEE 14- and 30-bus test systems showed speed-ups cl

Impact of OVL Variation on AUC Bias Estimated by Non-parametric Methodsriation on the AUC bias, samples from various continuous distributions were simulated considering different values for its parameters and for fixed OVL values between 0 and 1. Samples of dimensions 15, 30, 50 and 100 and 1000 bootstrap replicates for each scenario were considered.
