sym.nnet(
formula,
sym.data,
method = c("cm", "crm"),
hidden = c(10),
threshold = 0.05,
stepmax = 1e+05
)
formula |
a symbolic description of the model to be fitted. |
sym.data |
symbolic data.table |
method |
cm crm |
hidden |
a vector of integers specifying the number of hidden neurons (vertices) in each layer. |
threshold |
a numeric value specifying the threshold for the partial derivatives of the error function as stopping criteria. |
stepmax |
the maximum steps for the training of the neural network. Reaching this maximum leads to a stop of the neural network's training process. |
