> 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
