Data scoring

Running the data scoring task

After your predictive model is built, you can calculate scores for the given dataset.

For instance, if the goal of your project was to select the best target group for your marketing campaign, you would like to know the response probability for each customer in your database. In this task, ABM will assign the response probability (calculated based on the predictive model built by ABM) to your customers (identified by an ID variable which must be unique for each customer).

To start the scoring data task:

1. From the Homepage level, open the selected project by clicking on its name or click the Open project button

2. Click the Score data button (from the Project’s reports level)

The scoring data task is divided into six steps.

Step 1: Select a file for scoring

Step 2: Input detailed information about the file selected for scoring

Step 3: Choose the ID variable to which score values will be assigned (e.g. customer’s id)

Step 4: Start the data scoring process

Step 5: Download scoring result

And that’s it!

Step 1: Selecting file for scoring

Select an already uploaded file with the data that will be used for scoring. Currently, the .csv format is accepted (other formats are planned).

Remark: It’s crucial that the file for scoring and for model construction have the same structure:

• identical number of variables
• variables should have the same names and types

You can also add a new file by clicking the Browse for files button and by selecting the file from your computer. Upload the file with the Upload button and wait until it’s sent to the ABM server.

Choose the file by clicking its name and the Next button if you want to proceed to Step 2.

Step 2: Entering file settings

In Step 2 you will be asked to indicate what separators were used in the chosen file, including:

• Columns separators. For instance, if columns in CSV file are separated by a comma (e.g. name, email, age), write , in the first field
• Decimal separators. For instance, if a decimal character is a dot (e.g. 4.25) in CSV file, then write . in the second field
• Text separators. For instance, if a quotation mark is used to indicate the beginning and end of the text (e.g.’Baker Street 221b’), write ‘ in the third field
• File encoding. Choose the character encoding used in your file. If you need to add specific encoding to the list, contact us at abm_support@algolytics.com

Click the Next button if you want to proceed to Step 3 or the Back button if you want to change the previous project settings.

Step 3: Selecting identity variable

In Step 3 you will be asked to indicate the ID variable name. The ID variable is a variable with unique values which is used for identification of observations (e.g. customer ID). Scoring points will be assigned to this variable.

Click the Next button if you want to proceed or the Back button if you want to change the previous project settings.

Step 4: Running data scoring process

You’re almost there. Check if the information provided is correct. Click the Run button to start the scoring process or the Back button if you want to change the scoring process settings.

Step 5: Downloading scoring results

When the scoring process is finished you will see the following screen:

Click the Download button to see the scoring result. The output file is a .csv file containing three columns divided by commas:

• PositiveTargetProb: the probability of a positive value of the target variable (the situation when the phenomenon occurred, e.g. 1, the customer churned)
• Identity variable name: name of the chosen ID variable to which the probability will be assigned (e.g. customer id)
• PredictedTarget: the predicted value of the target variable. By default, if the threshold = 0.5, PredictedTarget will be equal to ‘1’ if the PositiveTargetProb >= 0.5, and to ‘0’ otherwise

You can also access the output file with the scoring results from the Repository.

Click the Back button to change the scoring process settings and to start the scoring process again. You can also return to model’s reports or go to ABM Homepage.
