The test and validation sets are made up of half of the prohibited substances (1,402) not used in the training set and half of the remaining inactives (55,487).
Manual validation of 2741 snippets reported that half of them contained correctly recognized entities and gene expression events, which is in line with the precision of TEES shown in Table 5. Curators reported that most mistakes concentrated on incomplete extraction of genes/proteins and cell types, such as the recognition of 'TGF' instead of 'TGF-beta'.
A validation cohort half the size of the training cohort was included, according to recommendations on design and analysis of metabolomics studies [ 30].
We used a cross-validation procedure to prevent overfitting: we partitioned the trials into a training set (random selection of half of the data) and a validation set (other half of the data), estimated the optimal weights in the training set, and used these weights to measure classification in the validation set.
Feature selection was performed on one half of the training fold, and validation of these features was performed on the other half.
The robustness of the ability to classify subspecies based on the DFA was further examined using a cross-validation where the discriminant function was generated from a random sample of half of the individuals and the remaining half was classified.
The data provide protein-level experimental validation for approximately half of the predicted protein-coding genes in Salmonella and suggest revisions to several genes that appear to have incorrectly assigned translational start sites, including a potential novel alternate start codon.
Our data provides protein-level experimental validation for approximately half of the predicted protein-coding genes in STM 14028 and suggests revisions to 47 genes assigned incorrect translational start sites, including a potential novel alternate start codon.
The other half consisted of epidemiological studies, case descriptions, and validation of measurement instruments.
Two-fold cross-validation, which uses half of the data for training and half for testing, was performed 10 times for both the SVM and the RF models.
