Particle competition and cooperation to prevent error propagation from mislabeled data in semi-supervised learning
(2012-12-01)
Semi-supervised learning is applied to classification problems where only a small portion of the data items is labeled. In these cases, the reliability of the labels is a crucial factor, because mislabeled items may propagate ...

Clustering on dissimilarity representations for detecting mislabelled seismic signals at nevado del ruiz volcano
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2007)
Classification of seismic signals at Colombian volcanoes has been carried out manually by visual inspection. In order to reduce the workload for the seismic analysts and to turn classification reliableand objective, the ...
Are we sure we eat what we buy? Fish mislabelling in Buenos Aires province, the largest sea food market in Argentina
(Elsevier Science, 2020-01)
The detection of substituted or mislabeled seafood may have different consequences on consumers and the environment, including economic losses due to potential commercial fraud, public health effects, uncontrolled impacts ...
The label “Cação” is a shark or a ray and can be a threatened species! Elasmobranch trade in Southern Brazil unveiled by DNA barcoding
(2020-06-01)
Sharks exhibit peculiar characteristics, which may lead to overfishing to cause irreversible damage to stocks and failing to restore original population sizes. Although global fin trade has decreased since 2000 meat trade ...
The fishing and illegal trade of the angelshark: DNA barcoding against misleading identifications
(Elsevier B.V., 2018-10-01)
Morphological identification in the field can be extremely difficult considering fragmentation of species for trade or high similarity between congeneric species. In this context, the shark group belonging to the genus ...
DNA Barcode reveals mislabelling in the identification of marine fish swimming bladders for commercialization
(2019-06-01)
Sequences of the mitochondrial gene COI (DNA Barcode) wereused to identify marine fish swimming bladders commercialized in Brazil. The comparisons of the obtained sequences of the samples registered as catfish for the ...
Exaggerating, mislabeling or simulating obsessive-compulsive symptoms: Case reports of patients claiming to have obsessive-compulsive disorder
(Elsevier B.V., 2014-07-01)
Background: There are no reported cases of factitious or simulated obsessive compulsive disorder (OCD). However, over the last years, our clinic has come across a number of individuals that seem to exaggerate, mislabel or ...
Discussion of “clustering on dissimilarity representations for detecting mislabelled seismic signals at nevado del ruiz volcano” by mauricio orozco-alzate, and césar germán castellanos-domínguez
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2008)
The authors are to be congratulated for a systematic investigationof the accurate and non subjective classifying approach in seismic research. The authors have conducted several clustering algorithms to the seismic event ...
