This paper is a continuation of previous paper where the imbalance dataset problem was solved by applying a proposed novel partitioning-undersampling technique. Then a proposed innovative Insurance Fraud Detection (IFD) models were designed using base-classifiers; Decision Tree, Support Vector Machine and Artificial Neural Network. This paper proposed an innovative insurance fraud detection mod...
Systems for face re-identification over a network of video surveillance cameras are designed with a limited amount of reference data, and may operate under complex environments. Furthermore, target individuals provide a small proportion of the facial captures for design and during operations, and these proportions may change over time according to operational conditions. Given a diversified poo...
Load balancing is one of the best efficient methods for performance improvement of cluster system. Recently, WLC algorithm is used for the load balancing of cluster system. But, the algorithm also has load imbalance between servers, because it uses inaccurate static load status of servers. In this paper, I suggest a more efficient dynamic load balancing algorithm base on various load status inf...
Estimating differences in gene expression among alleles is of high interest for many areas in biology and medicine. Here, we present a user-friendly software tool, Allim, to estimate allele-specific gene expression. Because mapping bias is a major problem for reliable estimates of allele-specific gene expression using RNA-seq, Allim combines two different strategies to account for the mapping b...
Coronavirus disease (COVID-19) can induce coagulopathy at the base of sepsis-induced coagulopathy (SIC), which is an important cause of death in these patients. Cytokine storm causes imbalance in coagulation and fibrinolytic system. A combination of hypercoagulability state, decrease or inhibition of fibrinolysis and endotheliopathy causes thromboembolic events. Underlying diseases such as diab...
Streaming data is pervasive in a multitude of data mining applications. One fundamental problem in the task of mining streaming data is distributional drift over time. Streams may also exhibit high and varying degrees of class imbalance, which can further complicate the task. In scenarios like these, class imbalance is particularly difficult to overcome and has not been as thoroughly studied. I...
Pico base stations are an important instrument to increase the capacity of mobile radio networks. Due to the limited spectrum availability it will be necessary to operate macro and pico base stations on the same frequency bands. In this case the transmit power imbalance between different base station types creates new interference situations. Coordinated beamforming is one method of base statio...
there is no doubt that breast-feeding is the best and safest way of feeding infants. physiological weight loss occurs in the first two or three days of life, and the achievement of birth weight is expected towards the end of the first week. hypernatremic dehydration may occur in exclusively breast-fed infants if milk supply is low during these first few days. it is not because of the high sodiu...
