Machine-Learning-Based Non-Destructive Evaluation of Refractory Anchor Welds via Analysis of Percussion-Induced Acoustic Signals
… models were evaluated using three progressively independent tests: a dependent 70:30 train-test split, a semi-independent test using newly recorded data from the same weld plate, and a fully independent test involving unseen anchors. Despite increased variability across tests, the supervised …

Inferring Extinct Reptilian Response To Global Warming: Insights From Modern Stable Isotope Ratios
… isotope geochemistry, however, provides an independent test. I analyzed stable isotope ratios (δ¹⁸O, δ¹³C) from enamel, providing new data on the connection between morphology, diet, and environment. I find a trophic separation in δ¹³C, and indications of aridity through δ¹⁸O. I applied this …

Prognostic models for mesothelioma : variable selection and machine learning
… levels that was 88% accurate on the set of 29 independent test samples, in terms of classifying whether or not the patients survived shorter or longer than the median survival [15]. These results were recreated both on the original data set used by Gordon et al and on a newer data set which …

Internet of Things and anomaly detection for the iron ore mining industry
… anomaly detection techniques. It is able, on an independent test data set, with an AUC of about 0.92, to detect 90% of the poor quality events, with a false positive rate of 23.02%, lowered by the dynamic cutoff algorithm. These methods can be applied to any factory in any industry, as long as it …

Combining linguistics and statistics for high-quality limited domain English-Chinese machine translation
… ran ten times faster and covered 15% more of the test set. In the machine translation component, a combined method of linguistic and statistical system is introduced. The English-Chinese translation is done via an intermediate language "Zhonglish", where the English-Zhonglish translation is …

Overactive conflict-monitoring and separation-distress : cognitive and affective components of obsessive-compulsive disorder ?
… The top 21 and bottom 20 scorers were then tested to gauge their levels of cognitive conflict-monitoring and separation-distress. Independent-test analysis revealed that the two groups differed significantly on scores of separation distress(as well as on the Affective Neuroscience …

B-Cell Epitope Prediction for Improved Antibody Docking
… sites, the success rate of a docking model on an independent test set can be increased by a factor of almost 10, with as little as 10 tries. Our approach is compatible with any docking model and offers an alternative to pure generative modeling, while being able to guarantee a diverse set of …
