Hello everyone!
I am trying to apply a ANN but is getting this error:
Error in cbind(1, pred) %*% weights[[num_hidden_layers + 1]] : requires numeric/complex matrix/vector arguments
I saw that its about using categorical data, but I have just numeric variables.
I've tried restart R and I checked the data frame, there is no NA values.
I've been trying for days and allways getting this same error.
Can someone help please?
