Applying negative boost to some documents after rescoring.

[meg261995]

Hi Team,

So I have a set of documents which are passed to my lambdamart model for rescoring. However after the rescoring, I still want to reduce the relevance of some of the documents. Is this possible? If not is there any other method to do this?

After the re-scoring phase you can no longer change the score of a document.

Could you use sorting on [condition, _score] to bury some of these unwanted docs? I guess you could also craft/insert features into your models if you wanted to handle it there.

Sorry for the very delayed response.
