We propose probabilistic framework for analysis of inaccuracies due to feature selection (FS) when flawed estimates of performance of feature subsets are utilized. The approach is based on analysis of random search FS procedure and postulation that joint distribution of true and estimated classification errors is known a priori. We derive expected values for the FS bias, a difference between ac...
studying forest degradation through evaluation of soil nutrient concentrations, which reveals soil functioning within the ecosystem, is necessary for sustainable management of land resources. this research was conducted to understand the changes of soil nutrient, resulting from exploitive management using some soil features and their spatial pattern. in the mid-summer of 2014, two sites were se...
With the fast increase of the documents, using Text Document Classification (TDC) methods has become a crucial matter. This paper presented a hybrid model of Invasive Weed Optimization (IWO) and Naive Bayes (NB) classifier (IWO-NB) for Feature Selection (FS) in order to reduce the big size of features space in TDC. TDC includes different actions such as text processing, feature extraction, form...
IMPORTANCE AND AIMS The role of CT colonography (CTC) as a colorectal cancer (CRC) screening test is uncertain. The aim of our trial was to compare participation and detection rate (DR) with sigmoidoscopy (flexible sigmoidoscopy (FS)) and CTC in a screening setting. DESIGN SETTING AND PARTICIPANTS We conducted two randomised clinical trials (RCTs). (1) Participation RCT: individuals, aged 58 ...
PURPOSE Intraoperative frozen section (FS) is an effective diagnostic test for periprosthetic joint infection (PJI). We evaluated the diagnostic characteristics of single- and multiplex-site intraoperative FS, and evaluated the results of single-site FS combined with those of C-reactive protein (CRP) level and erythrocyte sedimentation rate (ESR) for assessing PJI. METHODS We studied 156 pain...
UNLABELLED The role of intraoperative frozen sections (FS) during thyroidectomy is controversial. AIM to evaluate the role of FS for thyroid nodules management. PATIENTS AND METHODS All patients who had thyroid surgery for nodular disease and previous USG-guided FNAB in 2006 were prospectively analyzed. They underwent intraoperative FS evaluation, and the biopsy material was classified as b...
Sentinel lymph node biopsy (SLNB) is currently the suggested axillary staging procedure in patients with early-stage breast cancer (BC) and usually requires intraoperative frozen-section (FS) examination of the removed nodes. However, other techniques, such as touch imprint cytology (IC), real-time reverse transcriptase-polymerase chain reaction and rapid cytokeratin immunostaining on FS may be...
BACKGROUND & AIMS General practitioners (GPs) in the Netherlands have open access to flexible sigmoidoscopy (FS) for patients with lower gastrointestinal symptoms, but not to colonoscopy. This study was performed to investigate the yield of FS in GP-referred patients, to evaluate the proportion of patients in whom additional colonoscopy was performed and to investigate whether there was a subgr...
BACKGROUND Education and policy measures within schools are valuable strategies to promote health. This study explored views of experienced food-related educators, researchers and policy-makers regarding their recommended strategies to improve Australian adolescents' knowledge of nutrition and food systems (N&FS). METHODS Semi-structured interviews were conducted with twenty-one experienc...
BACKGROUND Flexible sigmoidoscopy (FS) is a safe and effective method for colorectal cancer (CRC) screening. Several studies have demonstrated that individuals who have undergone surgery are at a greater risk of having incomplete FS. This study explored predictors of incomplete FS and reduced polyp detection rates for participants who had undergone abdominal or pelvic surgery. METHODS From Ja...
