Social-spider optimization-based artificial neural networks training and its applications for Parkinson's disease identification
(Ieee, 2014-01-01)
Evolutionary algorithms have been widely used for Artificial Neural Networks (ANN) training, being the idea to update the neurons' weights using social dynamics of living organisms in order to decrease the classification ...
Neural Network Prediction of the Trabecular Bone Mechanical Competence Parameter
(Springer, 2014-01-01)
The mechanical competence parameter (MCP) has been defined to grade the trabecular bone fragility based on the principal component analysis (PCA) evaluated in terms of volume fraction, connectivity, tortuosity and Young ...
Application of neuro-fuzzy inference system on wood identification
(2014-01-01)
Searching for systems with intelligent, flexible, and self-adjusting solutions on imaging, which could provide the contraction of the human operators' presence, a range of techniques is found. Each one of them can control ...
Comparative study between RBF and radial-PPS neural networks
(Spie - Int Soc Optical Engineering, 1998-01-01)
The study of function approximation is motivated by the human limitation and inability to register and manipulate with exact precision the behavior variations of the physical nature of a phenomenon. These variations are ...
Neural-network-based approach applied to harmonic component estimation in microgrids
(2021-01-01)
Power quality in smart microgrids must be carefully analyzed, whereas adverse consequences may harm the electrical systems without power management and appropriate measures. The main goal of this paper is to develop a 5th, ...
Nonlinear phase noise compensation in single-span digital coherent optical systems employing artificial neural networks
(2021-05-31)
As digital coherent technology gets mature and its cost reduces, it is becoming a competitive solution for future implementations of high-capacity long-reach passive optical networks (LR-PON). In the case of single-channel ...
Tool condition monitoring of single-point dressing operation by digital signal processing of AE and AI
(Elsevier B.V., 2018-01-01)
This work aims at determining the right moment to stop single-point dressing the grinding wheel in order to optimize the grinding process as a whole. Acoustic emission signals and signal processing tools are used as primary ...
Identification of structural damage in flexible structures using system norm and neural networks
(2006-12-01)
Nowadays there is great interest in damage identification using non destructive tests. Predictive maintenance is one of the most important techniques that are based on analysis of vibrations and it consists basically of ...
Modelling and mapping the urban thermal environment
(2007-01-01)
In order to develop a methodology and tools that could help on thermal urban planning, this paper proposes a modelling of urban thermal environment based on the application of Artificial Neural Networks (ANN) and GIS tools. ...
