The only classifier that performs reasonably well, with AUC = 0.78, is based on EGFR features selected manually with emphasis on sites observed frequently (without consideration of cancer subtype).
A major problem of the ROI-based approach is the limited generalizability of the trained classifier, because the ROIs are selected based on features showing a between-group differentiation in the same groups in a univariate analysis.
Specific matching of codons and tRNAs is accomplished on ribosomes which select cognate tRNAs based on features of the geometry of the corresponding codon:anticodon duplexes [ 1].
First, we calculated the affine transformation matrix T to register the lung regions of each similar case with those of the objective case based on feature points, which were automatically selected for the registration in vertices of the circumscribed parallelepiped of the lung regions.
These results demonstrated that the MI-SVR combination can quite satisfactorily measure the importance of variables, increase interpretability, reduce the risk of overfitting, decrease complexity and generate predictive models for high dimension of variables based on selected features for complicated processing systems.
In other words, categorization results based on selected features should have maximum within-class similarity and minimum between-classes similarity.
In the serial implementation of Random Forest, the depth first method is adopted to split the nodes based on selected features.
These steps (clustering and embedding) are based on the selected features: compounds with similar feature values are likely to be clustered together into the same cluster.
For the feature-based blind recognition methods, the decision based on the selected feature function is another one major procedure.
It was also found, based on the selected features, that portions of the prefrontal cortex, orbitofrontal cortex, parietal lobe and insula regions provided the most discriminant features for classification, in line with results reported in previous studies.
