The confusion matrix that create ml gives you is only 20x20 but I am using 50 variables. Any way to increase its size?

Printing the confusion matrix (e.g. print(metrics.confusion) or metrics.confusion in a Playground) will only print the first 20 rows by default but all rows should be present in the underlying DataTable. Accessing or printing via slicing the confusion matrix, e.g. metrics.confusion[20:50], should allow you to see the other values.
