These two fields have been defined by me and the values depend on next days data. distributed. a method that instead of simply duplicating entries creates entries that are interpolations of the minority class, as well as undersamples the majority class. On the other hand, the major drawback of Random undersampling is that this method can discard useful data. The Pythonic way is probably to use zip and a list comprehension (25 chars): [x+y for x,y in zip(a,b)]. Without it, all strings will be printed out on the same line, which is what was happening in Tutorial 16. First, I create a perfectly balanced dataset and train a machine learning model with it which I'll call our " base model". Often, more than one contact to the same client was required, in order to access if the product (bank term deposit) would be ('yes') or not ('no') subscribed. This tutorial, for example, published by UCLA, is a great resource and one that I've consulted many times.
