|
normalize |
flags whether or not the normalized or combinatorial graph operator should be used. This is not used by ‘jtharm’. Further, it has no effect on anchor graph based approaches. |
stability |
stabilization parameter for necessary inverses. A NULL value allows it to be set internally (recommended) but can be set manually. |
k |
in fitting a distance graph with the ‘formula’ as y~. this will set the default k-NN graph parameter. It is not used otherwise. In the case of an anchor graph the k parameter is the number of anchors used by k-means. |
nok |
flags the y~. ‘formula’ call to either fit or not fit a k-NN parameter which overrides the k argument. |
dissimilar |
flags whether the graph is similar or dissimilar. This is not
necessary in the ‘formula’ call since a call to |
sfac |
the ‘s’ parameter for the LAE method. |
cn |
the ‘cn’ parameter for the LAE method. |
LAE.thresh |
thresh hold for LAE algorithm. |
LAE.eps |
convergence tolerance for LAE algorithm. |
iter.max |
maximum number of iterations for |
anchor.seed |
sets the seed for the |
sig.est |
use an internal estimation scheme to estimate the parameter for an rbf kernel. |
sig.frac |
when ‘sig.est’ is true, the fraction of training data necessary for the computaton is used. |
l.thresh |
max iteration parameter for the underlying logistic regression algorithm when fitting classification. |
l.eps |
threshold for stopping the underlying logistic regression algorithm when fitting classification. |
U.as.anchor |
if n>U.as.anchor.thresh then the anchor points are fitted as the unlabeled cases to speed up the approach. This only works in the formula call where the graph is unspecified, i.e., y~. |
U.as.anchor.thresh |
threshold for determining when the unlabeled are to be anchors. |
h.thresh |
minimum allowable choice for h in the grid used by CV. |
cv.fold |
the number of folds used for K-fold CV. |
cv.seed |
the seed to generate the folds for K-fold CV. |
cv.cl |
forces in classification at least two distinct responses in each fold and should be set to TRUE. |
cv.type |
use "scv" or "cv". The "scv" is faster and should be used. |
cv.adjust |
forces an inverse stabilization in "scv". |
