# ML Enrichments for Pipeline Workflows Profiles: Data Scientist, Project Creator Once your models are published, you can use them to enrich the data loaded from any source by adding the models to the pipeline workflow. To do this, you need to edit the pipeline workflow where you would like to add your published model. Tip: Once you have opened the pipeline overview, you can edit any pipeline workflow by clicking on the pencil symbol on the top right.

Under the _Classify_ section, all published models are shown. Here, you can choose the model you would like to use to enrich your data and add it to the pipeline via drag and drop.

If you have published multiple models in AI Studio, Squirro also allows you to add multiple models in your pipeline as different steps. Each of these models can serve a different purpose in enriching your data and can augment the insights for the end-users using Squirro’s dashboards.

The steps within a workflow typically include: - data loading - data cleaning - pre-processing - classification - generation of entities In a pipeline with similar ML workflows, identical steps are likely contained in multiple workflows. For example, the identical sentence splitting or PDF sentence tokenization step can appear in all or multiple ML workflows present in the pipeline. To avoid multiple executions of identical steps and increase the performance of the processing pipeline, you can enable the optimization of ML workflow execution. ### Configuration In the _Server_ space under _Configuration_, set the `machinelearning.optimize.workflows` to true: [](https://s3.amazonaws.com/download.squirro.net/docs/migrated-attachments/2680717393/2680684688.png)
