document: Learning weights for the quasi-weighted means We study the determination of weights for quasi-weighted means -LRB- also called quasi-linear means -RRB- when a set of examples is given . We consider first a simple case , the learning of weights for weighted means , and then we extend the approach to the more general case of a quasi-weighted mean . We consider the case of a known arbitrary generator f . The paper finishes considering the use of parametric functions that are suitable when the values to aggregate are measure values or ratio
