Christine Poerschke commented on SOLR-11838:
--------------------------------------------
bq. ... using a streaming expression to pull data from <somewhere> ...
I have not had an opportunity before to try out streaming expressions ... so
had a go and hacked up a proof-of-concept this evening (SOLR-11852) - the
connection to Deeplearning4j here could be for the pre-trained DL4J model
definitions to be stored <somewhere> and for contrib/ltr to be able to access
them from there via a streaming expression.
The pre-trained models would of course still have to be hydrated and for
contrib/ltr purposes the
[LTRScoringModel.java|https://github.com/apache/lucene-solr/blob/master/solr/contrib/ltr/src/java/org/apache/solr/ltr/model/LTRScoringModel.java]
base class to be implemented.

> bq. ... In my opinion, if this is a route Solr eventually wants to go, I

> [Deeplearning4j|https://deeplearning4j.org/] ...
> Creating this ticket for the idea to be explored further (if anyone is
> interested in exploring it), complimentary to and independent of the
> SOLR-11597 RankNet related effort.
