  • Back – Go up a time period (ex: Month to Year)


After selecting a project, a user is taken to the Data Transform view, where queries can have EDA operations added to them and then built into a Virtual Dataset (VDS).


  • Saved Workflows – Each row represents a query that has been saved and is eligible to have EDA operations performed on it. Can be dragged and reordered on the ‘Active Workflows’ space.
    • Federate – hover over to see the federates of all VDS’ contained in the saved workflow. If it is orange, then at least one of the VDS has an issue on a federate. If this icon is not visible, then all VDS’ on that workflow only exist on the logged in domain
    • VDS – The number of VDS created from the given workflow
    • Workflow name – This will appear red if any operations within the workflow have returned an error. The error will go away once the operation has returned successfully.

  • Federate – hover over to see the federates holding this VDS. If it is orange, then at least one of the federates is returning an error with the VDS.

Once a node is selected in the data transform space, you may use the arrow keys to navigate quickly between adjacent nodes.


Collapsing nodes with double click

Double clicking a node will collapse all children downstream from that node and add a superscript next to it, indicating how many nodes were collapsed. This can be useful in large, spread out trees.


Rearranging active workflows

Transform workflows in the active list can be rearranged in any order. This can be useful for comparing trees, or to bring two Virtual Datasets closer together to perform a merge.


Preparing Text Data for Model Training

Lucd provides special operations for easily preparing text data for model training, saving a model developer valuable time in manually coding routines for text transformation.


  • After creating an EDA tree based on a query of a text data source, a developer can add a new operation to the tree based on NLP operations as shown above.
  • NLP operations (e.g., stopword removal, whitespace removal, lemmatization) can be applied in any sequence.
  • It’s important to select the correct facet as the “text attribute.”
  • One can also elect to apply tokenization based on a document level (i.e., create one sequence of tokens for the entire facet value per record), or sentence level (i.e., create a token sequence per sentence in the facet for a record).

Saving VDS with Processed Text

When a developer wants to create a new virtual dataset including the transformed text data, they must choose the “processed_text” facet as the “sole” feature of the virtual dataset as shown below.


Currently, Lucd does not support text model training incorporating multiple feature columns, only the “processed_text” facet must be selected.

Multi-column text model training will be supported in a future release.

Applying Custom Operations

Once custom operations have been defined and uploaded using the Lucd Python Client library, they are available in the GUI for usage in data transformation.


As shown above, clicking on a custom operation will show further details, specifically the features the operation uses as well as the actual source code defining the op. As mentioned in the documentation for defining custom operations via the Lucd Python Client, one must select how to apply the operation based one of the following three Dask dataframe approaches:

Applying Image Operations

To apply image operations, select the Image Ops tab within the New Op menu in an EDA tree.


  • It’s important to select an image facet as the “Feature.”
  • The currently provided operations are as follows:
    Vertical and horizontal flips
    Grayscale Contrast normalization
    Normalize (0 mean and unit variance)
    Resize width & height
    Color inversion
    Crop borders
    Gaussian blur
    Min-max scaling
    To array (converts binary data to Numpy Array)
    Reshape dimensions

* Operations can be applied to percentages of a dataset instead of the entirety, and can also be used to augment existing data instead of operating in-place.

Query Builder

The Lucd client offers a unique and intuitive way to query data, giving a user flexibility in how complex queries are strung together to retrieve exact results.


  • Sources – a list of available sources to query. This can be dragged into the node editor window.
    • Quick add – click to add this source to the node editor window
    • Federate status – Hover to see which federates that hold the source. If this icon does not show, then the source only exists on the currently logged in domain.

Explainability Analysis

Lucd provides the ability to visualize “explanations” of a model’s output given specific inputs. Generally, explanations take the form of computed attribute weights, indicating the significance that an attribute gave to a model’s decision. This supports the ability to either debug a model or scrutinize the data fed to the model. This particular feature is supported by integration of the Lime framework. The figures below illustrate the explainability panel on the model profile view for various model types.

Explainability - Tabular/Regression

For analyzing a tabular model, the user enters sample(s) into the input text box as a list of lists of numbers, where each inner “list” is a single sample. Then click the “Explain” button underneath the box. The time required to run explanation analysis is dependent on the complexity of the model. Models with type tabular_classification or regression can explain tabular data predictions


  • Input Array
    • Enter values to predict on. Must be valid JSON, as shown above
  • % of Training Data
    • Percentage of training data to build the explainer. Must be greater than 0 and less than or equal to 1
  • Number of Top Explanations
    • Positive integer denoting how many class explanations to show
  • Inputs
    • Colored to show how each influences top class prediction
  • Class Probabilities
    • Class predictions and corresponding likelihood
  • Explanation
    • How each input influences a positive or negative prediction

Explainability - Images

Models with type image_classification can explain image predictions


  • Sample Image
    • Select local image to explain
  • Positive Only
    • If True, include only regions of the image contributing to the predicted label.
  • Hide Rest
    • If True, make the non-explanation part of the return image gray
  • Explanation
    • Returned colorized image with shaded regions of positive and negative influence. Red sections detract from the predicted class while green contributes positively to the predicted class.
  • Predicted Probabilities
    • Class predictions and corresponding likelihood

Explainability - Text

For text models, simply type the raw string you would like to have explained by your model. Models with type text_classification can explain text predictions.


  • Input Text
    • Text the user would like to predict and explain
  • Output Text
    • Output text with class probabilities highlighted in positive (green) or negative (blue) colors
  • Predicted Probabilities
    • Class probabilites predicted
  • Explanation
    • Words that contribute to positive or negative correlation



Federated Lucd


Release 6.5.0 introduces Federated Machine Learning to the Lucd platform. This capability introduces new features to the Lucd platform in order to support the development of federated models. Namely, if your Lucd platform is set up as part of a federation, many of the operations you perform within the JedAI client will automatically be federated. This includes:

  • Query: if your query matches data on multiple systems, you will get results from all of those systems.
  • EDA / search tree creation: saving your query into an eda tree will also create the eda tree on your other federates.
  • VDS: a vds created containing data from a federated query will in turn be created on all federates containing relevant data.
  • Model definition: model definitions uploaded you your JedAI GUI will also be created on other federates.
  • Training object: when training a federated model, a corresponding training object will be created on all participating federates.

Virtual Datasets


  • Open transform - opens the transform workflow that created this VDS
  • Copy ID - useful for finding VDS via RES API calls
  • Create an embedding
  • Delete - Delete a VDS
  • Refresh - retrieves the latest VDS data



  • Delete an embedding
  • Visualize - See embedding data on a PCA/TSNE chart
  • Refresh - retrieves the latest Asset data


Embeddings can be viewed using PCA/TSNE techniques for visualization.


  • Style - When viewing an embedding’s PCA/TSNE, click to see terms instead of points.
  • Region Select - Toggle to select a cluster of points using a bounding box.
  • Multiple Select - Use to add multiple bounding boxes.
  • Search - Search for a term. All matching terms will be highlighted, as well as shown in a list to the right until there is only one matching term.
  • Filter - Narrow the number of occurrences for a term to a range using.
  • Technique Select - Toggle between PCA and TSNE.
