In this paper, a hybrid meta-heuristic algorithm, based on imperialistic competition algorithm (ICA), harmony search (HS), and simulated annealing (SA) is presented. The body of the proposed hybrid algorithm is based on ICA. The proposed hybrid algorithm inherits the advantages of the process of harmony creation in HS algorithm to improve the exploitation phase of the ICA algorithm. In addition...

ICA decomposes a set of features into a basis whose components are statistically independent. It minimizes the statistical dependence between basis functions and searches for a linear transformation to express a set of features as a linear combination of statistically independent basis functions. Though ICA has found its application in face recognition, mostly spatial ICA was employed. Recently...

Abstract The detection of sensor faults has proven to be easier through data-driven methods which rely on historical data collected from sensors that are placed at various locations in a process plant. Since the distribution industrial variables is random and non-Gaussian, independent component analysis (ICA) method been better suited for fault (FD) problems. Whenever comes with any level noise...

Spatial smoothing is a widely used preprocessing step in functional magnetic resonance imaging (fMRI) data analysis. In this work, we report on the spatial smoothing effect on task-evoked fMRI brain functional mapping and functional connectivity. Initially, we decomposed the task fMRI data into a collection of components or networks by independent component analysis (ICA). The designed task par...

In this research, an integrated approach is presented to simultaneously solve quay crane scheduling and yard truck scheduling problems. A mathematical model was proposed considering the main real-world assumptions such as quay crane non-crossing, precedence constraints and variable berthing times for vessels with the aim of minimizing vessels completion time. Based on the numerical results, thi...

Reports indicate that employees are willing to share sensitive information under certain circumstances, and one-third half of security breaches tied insiders. These statistics reveal organizational efforts, which most often rely on deterrence-based sanctions address the insider threats security, insufficient. Thus, insiders’ computer abuse (ICA)—unauthorized deliberate misuse resources by insid...

An immunocytochemical assay (ICA) for the measurement of estrogen receptor (ER) and progesterone receptor (PgR) has been evaluated in 426 human primary breast carcinomas. For estrogen receptor determination ER ICA was used. PgR ICA was performed using the monoclonal antibody KD 68. Assay results for progesterone receptor immunocytochemistry were in agreement (P less than 0.0001) with those of b...

Binasal hemianopia is rare. It more commonly associated with ocular diseases than intracranial pathologies. Nevertheless, the proximity of internal carotid arteries (ICA) to visual pathway may cause a variety neurologic effects which lead loss. Although loss uncommon, ICA aneurysm compress optic nerve causing field defect and reduced acuity. We report 66-year-old male presented asymptomatic bin...

The aim of this paper is to analyze the differences in the classification accuracy obtained with raw EEG data and with data preprocessed with Independent Components Analysis (ICA). Our main research question is whether ICA is able to improve the classification accuracy not only in the case of a multichannel recording but also when EEG data are recorded only from a few channels. In order to answ...
