I have seen that the german credit data provides the following loss function in the german.doc. Why don't we use that?

This dataset requires use of a cost matrix (see below)
1 2
----------------------------
1 0 1
-----------------------
2 5 0

# (1 = Good,  2 = Bad)

It could be simply implemented by the following function.

def loss_function (predicted, actual):
    if (actual == predicted):
        return 0
    if (actual < predicted):
        return 1
    else:
        return 5
