At the beginning of the course, students did not know the parts or meanings of informative features on a phylogenetic representation.
Identification of informative features as obtained from the feature usage scores of DT revealed that the oligomeric interface are predominantly occupied by hydrophobic residues with a few electrostatic residues engaging in salt bridges.
'Curse of dimensionality' - an unresolved challenge in the design of an intelligent system makes dimensionality reduction a significant topic of research for the identification of informative features from high-dimensional data sets.
This method was developed by leveraging a comprehensive set of informative features extracted from multiple levels, including sequence, structure, and residue-contact network, in a random forest machine-learning framework.
While this drop in performance is not a definitive statement of the superiority of the STRF approach, it reflects that these two methods capture different levels of granularity in the signal, which provide different sets of informative features to a back-end classifier.
An L1-penalty term is commonly used in continuous model selection to identify a small set of informative features.
Thus, depending on the task difficulty (number of target and distractor stimuli, availability of informative features,.) CPs might perform with a normal accuracy.
Pathway-level analysis of informative features selected by different methods revealed a high level of congruency.
By increasing the penalty parameter lambda, weights of less informative features for each category shrink to zero; whereas weights of informative features remain non-zero.
In [ 6, 7] authors underline, that selection of informative features for a classifier is a crucial and delicate task.
