[jira] [Commented] (SOLR-11597) Implement RankNet.

JIRA jira@apache.org

    [ https://issues.apache.org/jira/browse/SOLR-11597?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16324712#comment-16324712 ]

Michael A. Alcorn commented on SOLR-11597:

[~cpoerschke] - yes, they are separate. RankNet is specifically a learning to rank model whereas the other architectures being discussed are more for modeling language. I describe how to train a RankNet model using Keras [here|https://github.com/airalcorn2/Solr-LTR#RankNet]. The weights can be exported from Keras in any format the user wants. The original Solr representation I suggested made it easy to export the weights from Keras since the weights are contained in matrices.
