This work shows a detailed description of the kNN method when using it for breast cancer diagnosis. We show the relation of the number of neighbors to the accuracy and also the change of accuracy with the change of the percentage of the data used for diagnosis. We also show details about the variation of the maximum and minimum values of the accuracy with the percentage of data used for diagnosis...
In everyday life, our brains integrate various kinds of information from different modalities to perceive our complex environment. Temporal synchrony of audiovisual stimuli is required for audiovisual integration. Many studies have shown that temporal asynchrony of visual-auditory stimuli can influence the interaction between visual and auditory stimulus, however, the multisensory mechanisms of asynchrony...
Current clinical foot posture assessment techniques rely on anthropometric measures of landmarks on the foot which can derive information regarding foot posture and foot problems. It has been identified that there is a source of error in these anthropometric measurements as a result of subjects having to maintain their weight bearing while balancing their examined foot on scales for the entire duration...
In this paper, we have given four confidence intervals estimator for the relative difference in matching pairs under inverse sampling. The performance of the proposed methods is evaluated with respect to their coverage probability, expected widths and RNCP(the ratios of the mesial non-coverage probability to the non-coverage probability). Our empirical results show that the confidence intervals based...
For insight into the laws of brain functional networks in the elder with different MMSE scores, 20 elders participated in our Opera experience task. We recorded their EEG at no-task and eyes-closed conditions. The elderly subjects were divided into high score group (HSG) and low score group (LSG) according to the MMSE score. The partially oriented coherent (PDC) values were computed separately in...
The study was to compare the characteristics of event-related potentials (ERPs) and brain topographic maps in normal group and cochlear implant (CI) group six months after device ‘switch on’. Results showed more negative N1 component by standard and target stimuli and lower P2 amplitudes were observed for the CI group. The amplitudes of MMN component were a little smaller than those of normal group...
In order to evaluate the heart function, it is valuable to detect and visualize the blood flow inside the left ventricle (LV) of the heart. In this paper, a method for flow detection in LV is proposed based on the echocardiography by using the speckle image velocimetry (SIV). It first segments the LV from the echocardiography and then conducts the SIV in the LV and estimates displacement vectors of...
Community detection is an important research issue in complex network mining. In this paper, firstly, we define central nodes, called Extended Local Max-Degree (ELMD) nodes in a complex network. All the central nodes are used for the community expanding. We also prove that ELMD method is more precise and dispersed than local max-degree method in the real datasets. Secondly, we propose an improved...
