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?
I'm assuming you mean the class
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:
