This paper proposes a new estimation algorithm for the parameters of an HMM as to best account for the observed data. In this model, in addition to the observation sequence, we have partial and noisy access to the hidden state sequence as side information. This access can be seen as “partial labeling” of the hidden states. Furthermore, we model possible mislabeling in the side information in a ...

The oyster industry is a significant component of United States aquaculture and vulnerable to various food frauds. In addition species substitution, mislabeling geographical origin performed for economic gains. misrepresentations are claim famed region known its unique flavor profile. DNA barcoding the gold standard method identifying seafood but has limited resolution level. This pilot study w...

Any chef in town knows what Lutjanus campechanus, also known as the red snapper, looks like. It is a pricey, medium-sized, light-red fish that weighs about 10 pounds. You may enjoy it fried, baked, broiled, poached, or sautéed. But what the chefs don’t know is that about 77% of red snappers sold in the United States are actually a mix of different species that includes some not-so-appreciated a...

DNA barcoding is a molecular technology that allows the identification of any biological species by amplifying, sequencing and querying the information from genic and/or intergenic standardized target regions belonging to the extranuclear genomes. Although these sequences represent a small fraction of the total DNA of a cell, both chloroplast and mitochondrial barcodes chosen for identifying pl...

Machine learning algorithms perform differently in settings with varying levels of training set mislabeling noise. Therefore, the choice of a good algorithm for a particular learning problem is crucial. In this paper, we introduce the “Sigmoid Rule” Framework focusing on the description of classifier behavior in noisy settings. The framework uses an existing model of the expected performance of...

The present study investigates through an integrated survey, for the first time in Greek shellfish market, marketing distribution towards a new edible product that of non-indigenous pearl oyster Pinctada imbricata radiata. survey conducted personal interviews on sector entrepreneurs/staff supply (i.e., producers, wholesalers, fishmongers, owners restaurants). Internet-based quantitative researc...

BACKGROUND Previous studies have reported the lower reference limit (LRL) of quantitative cord glucose-6-phosphate dehydrogenase (G6PD), but they have not used approved international statistical methodology. Using common standards is expecting to yield more true findings. Therefore, we aimed to estimate LRL of quantitative G6PD detection in healthy term neonates by using statistical analyses en...

The consumption of raw fish has increased considerably in the West, since it is said to be potentially healthier than processed fish (for containing omega 3 and 6, essential amino acids and vitamins). However this potential benefit, as well as the taste, value and even the risk of extinction are not the same for all species of fish, constituting grounds for fraud. Using the principles of the DN...
