The minimisation procedure adjusts the weights while training by using a learning rate \(\eta\) in a gradient descent algorithm, \(W(z) = W(z-1)- \eta \frac{\partial {E}}{\partial {W}}\), where z is the layer of the NN. Feature selection and feature importance Feature selection...
Decision making based on data leads to the discovery of new and exciting business opportunities. Drilling down into accessible visual information will give you a panoramic view of your business’s core activities, which, in turn, will ensure you make a series of solid decisions that benefit the ...
In the context of high-dimensional credit card fraud data, researchers and practitioners commonly utilize feature selection techniques to enhance the performance of fraud detection models. This study presents a comparison in model performance using the m
structurepredictionstructuralclasspredictionA neural network algorithm is applied to secondary structure and structural class prediction for a database of 318 nonhomologous protein chains. Significant improvement in accuracy is obtained as compared with performance on smaller databases. A systematic study of ...
“Methods” section for additional details on the data generation. For every field, the domain is segmented into Q events (see the “Results” section), and each one of these structures is considered an input feature to the SHAP algorithm. SHAP ranks the importance of each structure for ...

The aim of this paper is to develop efficient active learning algorithm for estimating Pf and Tθi,j. 3. Reliability analysis 3.1. Importance sampling (IS) Importance sampling is an efficient method in reliability assessment to reduce the Coefficient of Variation (CoV) of the MCS estimates. The...
The method of dependency of taskto-node and mode-to-node is designed and an evaluation algorithm is presented that both mission requirement and command mode are taken into account based on node importance of common network.Illustrative example is presented which shows the rationality and availability...
For if someone discovered that P = NP, and if moreover the algorithm was efficient in practice, that person could solve not merely one Millennium Problem but all seven of them—for she'd simply 4 need to program her computer to search for formal proofs of the other six conjectures.1 Of...
The statistical variability that is the basis of iris recognition is analysed in this paper using new large databases. The principle underlying the recognition algorithm is the failure of a test of statistical independence on iris phase structure encoded by multi-scale quadrature wavelets. Combinatorial...
