Christine Poerschke updated SOLR-11941:
---------------------------------------
    Description: 
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.

illustration/work-in-progress:
 * open pull request: 
[https://github.com/deeplearning4j/deeplearning4j/pull/4662]

deriving classes:
 * TestAdapterMode$CustomModel in the 
[TestAdapterModel.java|https://github.com/apache/lucene-solr/blob/master/solr/contrib/ltr/src/test/org/apache/solr/ltr/model/TestAdapterModel.java#L94]
 * future todo: when they exist add links to open-source models extending 
AbstractModel
