Active Learning Approach retraining of the model

I have a workflow built in studio, I go through the classification → extraction → validiation of data under a certain confidence threshold. My question is when I go into Action Center and validate the fields in question is that data automatically passed back into the model for retraining? If not, how do I achieve this?

Any help appreciated!

It would not pass directly…that is where you have a training module to be included…when there is a validation happened in those cases the task when resumed should use the doc and validated data to train…you have a train scope activity as well then upload those trained docs to ai center and there pipelines and skill creation can be set to automatic…this way when validation happens the data is retrained and new skill gets updated

Cheers

Okay I will need to look at the AI center. Currently I built the model in the modern experience and deployed from there.

I am finding answer to same query . In Classic approach we can re-train , but in modern i believe we are not using AI center so how can we re-train existing dataset. let me know if you are able to find the solution

@Anil_G , appreciate your help in this query .
In attached image is flow of Active learning process where i have imported UiPath .intelligentOCR activities also .

2.But in Activities tab in DU i can’t find Train extractor and Train classifier Activities. I want to use them to re-train the existing data set after it comes back from Action center.
3.


4.Please suggest how can we proceed on this in Modern Design document undersatnding in web/desktop based.
5. Do we have in-built framework here unlike we have in classic DU.

Use the activities under App Integration > Document Understanding.

@Kanika_Saluja

can you please recheck

cheers

When I use those activity options you have to select a project and private dataset which reside in AI Center. The modern approach in document understanding is deployed directly from document understanding and not through AI Center

My packages are identical to the picture you posted. However those rely on AI Center datasets so the modern approach document understanding project is not available in those options.

@Grant_Goebel

Can you please elaborate why they are not?

You have upload to dataset also in the activitirs which can be leveraged to upload docs to dataset

Cheers

Here is the deployment screen from DU. As you can see I have 2 versions one undeployed, one deployed. The deployed one I am able to classify, extract, and create validation station tasks.

If I go to my AI Center

There is nothing there so then when I use the tools mentioned in previous replies there are no datasets to pick from.

Just create a peoject and you can create same package here in ai center and use

Cheers

I went through and set up a workflow with the “Intelligent OCR” process which seems disconnected from the modern approach of DU. I had to recreate the taxonomy which seems like the same thing as creating the needed fields in the modern approach of DU. I get down to the “Train Extractors Scope” → “Machine Learning Extractor Trainer”. The issue I am running into there is when you deploy from the modern DU approach no ML skill exists inside of AI Center. I could set one up but I don’t understand how the two are connected and I would rather not go through the data labeling again since this is not a OOB model.

@Grant_Goebel

To retrain there must be atleast one…and to train you must select atleast one package

@Grant_Goebel @Anil_G , same thing exist for me. when you open UiPath desktop/UiPath web from Modern DU {image attached} , even if you import document understanding.ML activities & Intelligent OCR activities you are not able to see train classifier / extractors activities over there so retrain activities are not available for Modern approach . { as attached in above images}


2. Also , in classic process when you create DU project it auto links to AI center you need not to connect them explicitly; this is not available in modern project .
3.Also ,we don’t see any options for dataset endpoints in Modern since we can’t find any project details on AI center.

Please let me know if we have any workaround for them.

It took me a while to see this, but I have the answer.

The ‘modern’ DU activities do not yet support a native re-training loop.
However I wrote a tutorial of how you can achieve this by leveraging some of the classic activities in combination.
Its quite tricky, but see my tutorial here.
