CC and RR reviewed the case report form and supervised study performance within the Spanish Lung Cancer Group.
The supervised classifiers performance is affected for the same reason and also by the difference in data distribution between the train and test sets [ 57].
The importance of including large numbers of carriers is once again demonstrated, even if the semi-supervised learning performance here, as compared to the fully supervised case, while good, is less impressive than on the home set.
Integration of consensus clustering with semi-supervised clustering improved performance as compared to using consensus clustering or semi-supervised clustering separately.
We also tested a scenario when foreign data was used in a semi-supervised way; the performance gains obtained by both kinds of foreign data were then noticeably lower than in the supervised case, but followed the same trend.

While unsupervised and semi-supervised methods are currently unable to match the performance of supervised learning methods, research is limited and results are inconclusive, warranting further investigation.
The performance of supervised statistical classifiers often depends on the availability of labeled examples.
The performance of supervised learning algorithms is discussed in terms of computational effort.
Some studies showed that the linguistic features, such as lemmatisers and stemmers, decrease the performance of supervised CNER systems [49], while POS and chuckers are normally used.
