SYNOPSIS
MakeDiff [options] Group DiffGroup Net
DESCRIPTION
Creates a new group 'DiffGroup' with the same number of hidden units as 'Group',
and connects them with time-delay and look-ahead connections in such a way
that the activities of the new units are an estimate of the first order time
derivative of the activities of the old units. The regression analysis is the
same as that of the HTK toolkit from Cambridge and the StarLite ASR module at
KTH. Higher order derivatives can be computed by running MakeDiff again on the
created group.
OPTIONS
-r lag
Specifies the order of the regression analysis. 'lag' specifies the maximum
forward and backward time-lag of the created connections. The default is 2.
-p plast
Set plastictity of created connections. The default plasticity is 0.0, which
is different from the normal default 1.0.
