+Note, that the weights have the same order as hypotheses in partial forgetting, and follow this scheme:
 \li 0 means that the parameter doesn't change,
 \li 1 means that the parameter varies.
 
 The combinations of parameters are described binary:
-\f[
-  0, 0, 0\ldots \\
-  1, 0, 0\ldots \\
-  0, 1, 0\ldots \\
-  1, 1, 0\ldots \\
-  \ldots
-\f]
-where each n-th column has altering 1's and 0's in n-tuples, n = 0,...,number of params. Hence, the first forg. factor relates to the situation when no parameter changes, the second one when the first parameter changes etc.
