Importance of features? #36

Open bittlingmayer opened 8 years ago

bittlingmayer commented 8 years ago

Is there any list of the features ranked or reduced by importance? Or are those features that are in the source precisely those which were determined to be necessary for optimal performance?

We would like to submit and compare our own ranking. If it varied significantly for the same training data, that could mean one of us has a bug or other subtle difference in implementation.

As far as I know, there is no such list. In QuEst, you usually perform feature selection during model training :)

Hi,

We've done lots of feature analyses (see e.g. http://link.springer.com/article/10.1007%2Fs10590-014-9164-x) , but the ideal set is often dependent on your data/labels, so what Gustavo is suggesting is the best option.

Best, Lucia
