there is a slightly improved version of the Probe Method.
With the original one there is one problem.
If you have thousand features and you reiterate the Probe Method for a couple of times you'll get different number of useful features. There is some randomness in that process. So you can insert not one but say 3-5 of noise features and drop by the worst of them. It will be the least aggressive and greedy approach possible.
What happens if the random feature happens to be a very important feature? Should the engineer make sure that the random feature is far away from some existing feature?

Then repeat, as in the article

The last time my team tried this, the importance of the random feature was zero :/
