I wonder if the information contained in SignatureType is identical to the information contained in typeof(Scorer) ?
As in, aren't these the type parameters you want to invoke with? #Closed

The parameter information definitely overlaps, but this isn't duplicate information.
For example, if there are two signature delegates:
publicdelegatevoidSignatureSweeper();publicdelegatevoidSignatureTrainer();We can't discern which one we are trying to load from the component catalog solely on signature (both these signature delegates don't take any more parameters other than the Environment). #Closed

Oh, I see. So the signature is needed for subselecting a list.

The signature is needed in order to find the component in the ComponentCatalog. We can have multiple components with the same name, but are different based on their "signature type". So the components are keyed off both a name and a signature type:

why don't we put the 'if' outside the delegate and construct specialized delegates? #Closed

IComponentFactory<IDataView, ISchemaBoundMapper, RoleMappedSchema, IDataScorerTransform> [](start = 12, length = 88)
can you define something like using TScorerFactory = IComponentFactory<IDataView, ISchemaBoundMapper, RoleMappedSchema, IDataScorerTransform> and use it across this file?
see line 17 in MetaMulticlassTrainer.

@Ivanidzo4ka and @Zruty0 I've responded to all feedback. Please take another look. |

Yes, I will take care of all the SimpleComponentFactory classes being hidden in #681.
Also, PartitionedFileLoader is now SubComponent-free.
This is the next round of SubComponent removal from our public API. I've removed all
ScorerandCalibratorusages of SubComponent.@Ivanidzo4ka - I still need to update this so CmdParser doesn't throw an exception. I'll do that when I'm back in the office. I wanted to send this out now to get eyes on it while I'm out.
