%description
An implementation of feature selection, weighting and ranking via
simultaneous perturbation stochastic approximation (SPSA). The SPSA-FSR
algorithm searches for a locally optimal set of features that yield the
best predictive performance using some error measures such as mean squared
error (for regression problems) and accuracy rate (for classification
problems).
