Density-based clustering validation
(Society for Industrial and Applied Mathematics - SIAMPhiladelphia, 2014-04)
One of the most challenging aspects of clustering is validation, which is the objective and quantitative assessment of clustering results. A number of different relative validity criteria have been proposed for the validation ...
Estimating hardness of eucalyptus wood with a portable hardness tester
(2012-12-01)
More than 80% of the 29600 km of the Brazilian railroad mesh employs wooden sleepers. The problem of hard availability of native wood for this purpose leads to the alternative use of reforestation species to produce sleepers. ...
GDP 4.0 transfer to SGP 3.0 for SCIAMACHY no2 column processing: Verification with SDOAS / GDOAS prototype algorithms and delta-validation with NDACC / UV-visible network data
(2007-02-01)
Until mid 2006, SCIAMACHY data processors for the operational retrieval of nitrogen dioxide (NO2) column data were based on the historical version 2 of the GOME Data Processor (GDP). On top of known problems inherent to ...
On the internal evaluation of unsupervised outlier detection
(University of CaliforniaAssociation for Computing Machinery – ACMLa Jolla, 2015-06)
Although there is a large and growing literature that tackles the unsupervised outlier detection problem, the unsupervised evaluation of outlier detection results is still virtually untouched in the literature. The so-called ...
