www.frontiersinecology.org © The Ecological Society of America I little more than a decade, the rapid and widespread use of genetic identification protocols has transformed food authenticity testing from a niche area into a highly influential biotechnological application worldwide (Ogden 2008; Yancy et al. 2008; Lou 2015). Although livestock and agricultural products remain the main focus of ce...
The worldwide advent of concentrated supplements containing omega-3 fatty acids (FA) in the form triacylglycerols (TAG) or ethyl esters (EE) has increased interest developing methods to classify these products. quality control based on their lipid composition become necessary since EE bioavailability been proved be lower when compared TAG. In this preliminary study, eight models 1H NMR and supe...
Classification model performance can be degraded by label noise in the training set. The sentiment classification domain also struggles with this issue, whereby customer reviews mislabeled. Some customers give a rating score for product or service that is inconsistent review content. If business owners are only interested overall picture includes mislabeling, lead to erroneous decisions. Theref...
Abstract We propose a method for certifying the fairness of classification result widely used supervised learning algorithm, k -nearest neighbors (KNN), under assumption that training data may have historical bias caused by systematic mislabeling samples from protected minority group. To best our knowledge, this is first certification KNN based on three variants definition: individual fairness,...
The production area mislabeling of a food product is considered fraudulent practice worldwide. In this work, method that uses ultra-high-performance liquid chromatography coupled to high-resolution mass spectrometry using atmospheric pressure chemical ionization (UHPLC–APCI–HRMS) was used for the geographical origin authentication paprika based on determination capsaicinoids and carotenoids. Sa...
Paprika production under the protected designation of origin (PDO) standardized procedures leads to more quality products. However, it is also related higher retail prices, making them susceptible adulteration with low-quality paprika or its agricultural origin’s mislabeling. Therefore, in this study, high-performance liquid chromatography fluorescence detection (HPLC-FLD) fingerprints, strongl...
BACKGROUND During specimen processing in surgical pathology laboratories, specimen-related adverse events (SRAEs), such as mislabeling and specimen mixed-up might occur. In these situations, molecular techniques using short tandem repeat (STR) loci are required to identify the personal identity. Microsatellite instability (MSI) test is widely used for screening the hereditary non-polyposis colo...
Recent Supreme Court decisions emphasize the need to regulate the admissibility of expert testimony by means of standards that require opinions to go beyond ipse dixit--that is, that are based on more than the fact that the expert said it. The authors discuss subtextual themes underlying this issue and suggest approaches to attaining expert clinical opinions that reduce the likelihood of being ...
