[HTML][HTML] UFFizi: a generic platform for ranking informative features
Background Feature selection is an important pre-processing task in the analysis of complex
data. Selecting an appropriate subset of features can improve classification or clustering and
lead to better understanding of the data. An important example is that of finding an
informative group of genes out of thousands that appear in gene-expression analysis.
Numerous supervised methods have been suggested but only a few unsupervised ones
exist. Unsupervised Feature Filtering (UFF) is such a method, based on an entropy measure�…
