Building Algorithm Flow in a Workbook Canvas

Building Algorithm Flow in a Workbook Canvas

The workbook canvas is your experimental area.
You can create, run, and train your algorithm flow in workbook canvas using a simple drag-and-drop method, to add datasets and algorithms.
The table given below provides major differences between the workbook and workflow.

Workbook Canvas

Workflow Canvas

It is an experimental area where you train your datasets and algorithms. 

It is the production area where trained datasets are used to publish your algorithms as models. 

It also contains classification and regression algorithms, along with other algorithms. 

It contains all algorithms present in the workbook, except classification and regression algorithms. 

You cannot schedule algorithms to run later. 

You can schedule your final algorithms to run automatically at specific time intervals.

To use canvas, follow the steps given below.

Notes:

  • It is recommended to save your Workbook after every step. This ensures all the changes are saved.
  • To save the workbook, click the Save icon ().
  1. Open the Workspace where you want to create your workbook. Refer to Changing Workspace.
  2. Create a Workbook. Refer to Creating a Workbook.

  3. Use the drag-and-drop method to insert readers and algorithms from the Task Pane into the canvas.

    (info) Note: 

    You can also double-click on the reader or algorithm to add it to the canvas.




  4. Click the reader/algorithm and click the Node Connector, and then click the other reader/algorithm that you want to join with it.
    Similarly, join the other elements.

    (info) Note: 

    You can also join a single element to multiple elements if required.


  5. Click the reader/algorithm and select the Properties displayed on the right-hand side.
    Here we have selected Data Fields (columns in your dataset) for the selected reader.

  6. Click the reader/algorithm and click the vertical ellipsis (). The functions available for the elements are as follows.

    (info) Note: 

    Publish as a model is available only for Machine Learning, Regression, and Classification algorithms.

    The table given below describes the functions present on the reader or algorithm.

    Icon Name

    Description

    Run

    It runs the selected node of the algorithm. Note: The predecessor node is expected to be successfully executed.

    Run from Node

    It runs all the nodes below, from the selected node.
    Note: All nodes before this node are expected to be successfully executed.

    Run till Node

    It runs all the nodes from the top node, until the selected node.

    Explore

    It lets you explore the result of the selected node.
    Note: You can explore only after the algorithm is successfully executed.

    Publish as a Model

    It publishes the algorithm flow as a model.
    Note: You can publish models only in Data integrator for Machine Learning algorithms.

    Delete

    It deletes the node.

  7. Click the Save icon () on the function pane, to save the algorithm flow.

(info)Notes:

  • To run the algorithm, click the Run icon (). For more information refer to Running a Workbook.
  • To stop the execution before completion, click the Abort icon ().
  • You can publish your models only if you are working in data integrator. For publishing your models, refer to Publishing as a Model.
