I was reading an article about a winning solution to the Criteo competition on Kaggle. There was also some talk of the third place solution. Here is the excerpt:
Highest scoring team using Vowpal Wabbit was Guocong Song for 3rd place. Method and code here. In short: Multiple models, polynomial learning and featuremasks.*
In this it mentions the use of Feature Mask or Featuremasks. Whatis meant by this? I am struggling to find good examples anywhere on the internet.
*emphasis my own.
