A matrix of multiclass 0/1 indicators

y_pred

A matrix of predicted probability of each class

Value

The value of multiclass cross entropy

Examples

# NOT RUN {
data(iris, package = "datasets")
Y <- iris[, 5]
X <- scale(iris[, 1:4])
pnet <- pnn.fit(x = X, y = Y)
logl(y_true = pnet$y.ind, y_pred = pnn.predict(pnet, X))
# }
