Edit existing variable


Welcome to the OtasML Edit Variable Page documentation. This guide will walk you through the process of editing an existing variable using the "Edit Variable" page within the OtasML platform. By the end of this guide, you'll be able to modify and update variables that are essential for your machine learning models. After creating a new variable, the user can edit the selected variable by clicking on the edit icon next to the variable selection on the "View All" page.


  • An active OtasML account.
  • Access to the OtasML platform.
  • Basic understanding of machine learning concepts such as variables, features, and target values.
  • An existing variable created within OtasML.

Step-by-Step Guide

  • Step 1:
    • Log in to your OtasML account.
    • On the left sidebar, click on Variables.
  • Step 2:
    • On the "View All" page, find the variable you want to edit.
    • Click on the Edit icon next to the selected variable.
  • Step 3:

On the "Edit Variable" page, you will see several fields to update your variable. Complete each field as described below:

  • Variable Name
    • Default Value: None
    • Description: Choose meaningful and descriptive variable names to identify and differentiate your variables from others effectively.
  • Operation Name
    • Default Value: None
    • Description: Please select one operation from the list to associate your variable with that operation.
    • Note: The original data will be automatically loaded when the user accesses the edit variable page.
  • Input
    • Default Value: None
    • Description: Input, also known as independent variables, feature set, or X, is a matrix containing the feature values. Each column in the matrix represents one feature with known values. Each column of X represents an independent variable.
  • Output
    • Default Value: None
    • Description: Output, also known as the dependent/target variable or y, is a vector containing the target values that you want to predict. The y vector may have one or more columns, representing different target variables.
  • Step 4:
    • Review the details you've updated to ensure accuracy.
    • Click the Save button to update the variable.


  • Q1: What should I do if the variable name exceeds 30 characters?
    • A1: Shorten the variable name to be within 30 characters while maintaining its descriptiveness.
  • Q2: Can I edit multiple variables simultaneously?
    • A2: No, you can only edit one variable at a time. Repeat the steps to edit additional variables.
  • Q3: What happens if I change the operation name?
    • A3: Changing the operation name will associate the variable with the new operation. Ensure the new operation is appropriate for the variable.


  • Issue: Unable to save the updated variable.
    • Solution: Ensure all required fields are filled in correctly, and the variable name does not exceed 30 characters.
  • Issue: The page is not loading correctly.
    • Solution: Refresh the page or try logging out and back in. If the issue persists, contact support.
