In order to reduce the effect of numerical weather prediction (NWP) error on short term load forecasting (STLF) and improve the forecasting accuracy, a new hybrid model based on support vector regression (SVR) optimized by an artificial bee colony (ABC) algorithm (ABC-SVR) and seasonal autoregressive integrated moving average (SARIMA) model is proposed. According to the different day types and ...

In this paper, the support vector regression (SVR) methodology was adopted to estimate the horizontal global solar radiation (HGSR) based upon sunshine hours (n) and maximum possible sunshine hours (N) as input parameters. The capability of two SVRs of radial basis function (rbf) and polynomial basis function (poly) was investigated and compared with the conventional sunshine duration-based emp...

Budgeting planning plays an important role in coordinating activities in organizations. An accurate sales volume forecasting is the key to the entire budgeting process. All of the other parts of the master budget are dependent on the sales volume forecasting in some way. If the sales volume forecasting is sloppily done, then the rest of the budgeting process is largely a waste of time. Therefor...

BACKGROUND The role of apoptosis in treatment-induced HCV clearance is controversial. We sought to assess the kinetics of serum apoptosis-related cytokines during pegylated interferon-α2a or -α2b plus weight-based ribavirin therapy for genotype 1 chronic HCV infection. METHODS Serum levels of soluble Fas (sFas), soluble Fas ligand (sFasL) and soluble tumour necrosis factor receptor I (sTNF-RI...

Support vector regression (SVR) has been widely used to reduce the high computational cost of computer simulation. SVR assumes input parameters have equal sample sizes, but unequal sizes are often encountered in engineering practices. To solve this issue, a new prediction approach based on SVR, namely as high-low level (HL-SVR) is proposed for data modeling paper. The consists low-level models ...

Hybrid metaheuristic algorithm (MA), an advanced tool in the artificial intelligence field, provides precise reference evapotranspiration (ETo) prediction that is highly important for water resource availability and hydrological studies. However, hybrid MAs are quite scarcely used to predict ETo existing literature. To this end, abilities of two support vector regression (SVR) models coupled wi...

results in patients with an svr, the serum levels of aminotransferases were decreased after hcv eradication. although general liver functional tests (albumin and total bilirubin) did not significantly change, the btr values significantly increased. however, in patients without an svr, an improvement in the btr value was not observed after ifn treatment. conclusions hcv eradication can improve t...

BACKGROUND AND RATIONALE Age is one of the predictors for sustained virological response (SVR) when treating chronic hepatitis C (CHC) patients with pegylated-interferon/ribavirin (PegIFN/RBV). However, the treatment responses of the young patients had not been analyzed before. Therefore, we conducted this study to investigate the treatment responses of CHC patients younger than 40 years old (y...

BACKGROUND To compare on-treatment and off-treatment parameters acquired using acoustic radiation force impulse elastography, the Fibrosis-4 (FIB-4) index, and aspartate aminotransferase-to-platelet ratio index (APRI) in patients with chronic hepatitis C (CHC). METHODS Patients received therapies based on pegylated interferon or direct-acting antiviral agents. The changes in paired patient pa...

BACKGROUND An estimated 170 million people worldwide are infected with hepatitis C virus (HCV). HCV genotype 4 (HCV-4)-the most prevalent hepatitis C strain in the Middle East and Africa-is difficult to treat, with an estimated sustained virological response (SVR) of 53% when using pegylated interferon and ribavirin (P/R) in treatment-naïve patients with HCV-4 infection. In regions where access...
