A new idea to suggest a product enhancement or new feature


Suggest an idea

I'm really liking the new assisted modelling capabilities released in 2020.2, but it should not error if the data contains: spatial, blob, date, datetime, or datetime types.

 

This is essentially telling the user to add an extra step of adding a select before the assisted modelling tool and then a join after the models. I think the tool should be able to read in and through these field types (especially dates) and just not use them in any of the modelling.

 

An even better enhancement would be to transform date as part of the assisted modelling into something usable for the modelling (season, month, day of week, etc.)

It would be great if it was possible to output the top most influential features in producing the score for each individual entity/row when using the predictive and machine learning tools.

 

Similar to the way they work in DataRobot. Details here and here.

 

This would enable some simple interpretation of how a model came to an individual prediction and the most important features in that particular row/case.

Model evaluation (including feature importance) is only available in assisted modelling within the machine learning tools.

 

It would be great if there was a tool to do this when using the expert mode so that you could see some standard performance metrics for your model(s) and view the feature importance.

Assisted modeling is a great idea but right now it's a bit unflexible.

IMHO the greatest strength is the semi-automated transform tool, which would extremely helpful on its own.

 

What would be great is the possibility of using the features without having to go through the assisted modeling wizard but as single tools with minimal configuration, so that it could be used as an automated system for quickly choosing variables.

This way we could have a pretty much perfect rapid prototyping tool for machine learning tasks, leaving more freedom in modeling and enabling less skilled analysts in easily finding on which variables they should focus.

 

What do you think?

Hello,

 

as shown in the Alteryx Inspire Demo, Assisted modeling is going to work with a wizard and generate several tools as result.

The data evaluation functions and feature engineering assist however would be extremely useful tools in their own, is there any chance we can use them as separate tools in the upcoming version?

 

Thanks in advance!
