These functions compute several performance measures to compare the predicted values of a SVM model to the expected values of a given test data set. For more details, have a look on page 8 in the LIBSVM paper

val calc_n_correct : Lacaml.D.vec -> Lacaml.D.vec -> int

calc_n_correct expected predicted

returns
the number of correctly predicted labels.

raises Invalid_argument
if the vector dimensions do not match.

val calc_accuracy : Lacaml.D.vec -> Lacaml.D.vec -> float

calc_accuracy expected predicted

returns
the ratio (in percent) of correctly predicted labels to the number of all labels.

raises Invalid_argument
if the vector dimensions do not match.

val calc_mse : Lacaml.D.vec -> Lacaml.D.vec -> float

calc_mse expected predicted

returns
the mean sum of squared errors.

raises Invalid_argument
if the vector dimensions do not match.

val calc_scc : Lacaml.D.vec -> Lacaml.D.vec -> float

calc_scc expected predicted

returns
the squared correlation coefficient.

raises Invalid_argument
if the vector dimensions do not match.
