R: Error in nrow[w] * ncol[w] : non-numeric argument to binary operator, while using neuralnet package

Question

I am using neuralnet package for training a classifier. The training data looks like this:

> head(train_data)
   mvar_12      mvar_40 v10       mvar_1            


        

Answer 1

Try adjusting the threshold to a higher than 0.01 value or the stepmax to more than 1e06, or using a threshold of 0.1 and then decreasing it from there. You can also add in the lifesign = "full" argument to observe the model creation performance in increments of 1000 steps to really dial in the threshold. This "resolved" the non-binary error I had, but the accuracy of the model, the mean squared error, and other results were less than satisfying as a direct result.
