Description Usage Arguments Details Value References Examples
Given the value of an attribute (v1) and the
reference point of the same attribute (v2), calculates the loss and returns it [1,2]. It
is not built as a stand alone function, rather as an object to be used by
other major functions, such as gainMarix, lossMatrix
.
1 | lossFunction(v1, v2)
|
v1 |
value of attribute j in round i |
v2 |
reference point of attribute j |
For understanding how this works, see the function itself or refer to the paper. It handles only discrete numbers, so no interval numbers. Also a point to improve further on.
loss, numeric value.
