             Summary: add abstract contrib/ltr AdapterModel
                 Key: SOLR-11941
                 URL: https://issues.apache.org/jira/browse/SOLR-11941
             Project: Solr
          Issue Type: New Feature
          Components: contrib - LTR
            Reporter: Christine Poerschke
            Assignee: Christine Poerschke


The abstract AdapterModel class is to facilitate the development of open-source 
(or custom) scoring models whose initialization is completed when a 
SolrResourceLoader is supplied in the init method call. Via the 
SolrResourceLoader a file defining an pre-trained model can be opened and once 
instantiated the LTRScoringModel.score() method can delegate calculations to 
the implementing model instance.

* MultiLayerNetworkLTRScoringModel.java in 
https://issues.apache.org/jira/secure/attachment/12908198/SOLR-11838.patch

work-in-progress:
* todo: add link to my upcoming deeplearning4j pull request here

deriving classes:
* todo: once it's committed add link to the CustomModel in the 
TestAdapterModel.java
* future todo: when they exist add links to open-source models extending 
AbstractModel
