Remarks

This trainer attempts to solve the problem

$\min_{w} \sum_{i=0}^{n-1} e(y_i, \hat{y}_i)$

where w are the weights, n is the number of training patterns,

is a training target output and $\hat{y}_i$ is its forecast value.

This interface defines the function $e(y,\hat{y})$ and its derivative with respect to its computed value, $de/d\hat{y}$ .
