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.
> Implement RankNet.
