Pipelines in DAAL

Pipelines in DAAL

Hi,

I'm looking to set up an online-learning pipeline in DAAL, and would like to replicate existing (working) scikit-learn code I have built around their Pipeline object. Is there a similar object in pyDAAL, and if so can anyone point me to a code containing it?

Thanks!

Matt

Hi Matt,

Can you give an example how your pipeline looks like? What transforms does it involve?

Hi,

Sorry for the slow reply. The current workflow involves multiple LabelEncoder (one applied to each of a list of columns), a StandardScaler, and an SVM algorithm.

Hi Sergey -

Any update on this?

Thanks!

Matt

Matt, 

I'm assuming you mean the class sklearn.pipeline.Pipeline.

No DAAL does not have an equivalent pipeline class. However sklearn allows for custom transformers to be inserted into their pipeline object. The custom transformer is an object you create yourself, with the requirement of "fit" and "transform" methods.

You can build a smaller wrapper object around DAAL algo object, and insert it into sklearn's pipeline as a custom transformer. 

There is a nice blog about this here:
