Scenario

The models for the U+Bank implementation of cross-selling on the web of their credit cards have been learning for some time. Your task in this challenge is to inspect the models and report on which predictors are performing well, and which are not.

Use the following credentials to log in to the exercise system:

Role User name Password
Data scientist DataScientist rules

Your assignment consists of the following tasks:

Task 1: Inspect the adaptive models

Inspect the adaptive models by answering the following questions:

  1. Which model requires attention, and what is the performance of this model?
  2. What is the performance of the two best-performing models?
  3. What is the performance of the two worst-performing models, and what is their number of responses?
  4. Which banner is the most successful?

Task 2: Inspect the predictors of the models

Inspect the predictors in the models by answering the following questions:

  1. Which two predictors have the highest performance across all models?
  2. Which predictors are not used in any of the models?

Task 3: Inspect a specific adaptive model

Identify the model with the highest performance, then inspect it and answer the following questions:

  1. What are the top three predictors used in the model?
  2. Which predictor, which is not currently relevant to the adaptive model, has the highest performance?
  3. Which age categories show the highest and lowest interest in this banner?

 

You must initiate your own Pega instance to complete this Challenge.

Initialization may take up to 5 minutes so please be patient.

Detailed Tasks

1 Inspect the adaptive models

  1. On the exercise system landing page, click Pega CRM suite. to open Customer Decision Hub.
  2. Log in as a data scientist:
    1. In the User name field, enter DataScientist.
    2. In the Password field, enter rules.
  3. In the navigation pane of Customer Decision Hub, click Intelligence > Prediction Studio to open Prediction Studio.
  4. On the Predict Web Propensity tile, click Open prediction to edit the web propensity prediction.
  5. On the Models tab of the prediction, in the Supporting models section, click Web_Click Through_Rate to open the adaptive model configuration.
    The supporting model section of the prediction
  6. On the Monitor > Models tab, inspect the bubble chart.
    The bubble chart with models
    Note: In this web scenario, the success rate of the model is the click-through rate, the fraction of customers that clicks on the banner. The performance is measured as Area Under the Curve (AUC) and has a value in the range of 50 to 100.
  1. Question - Which model requires attention, and what is the performance of this model?
    1. Hover over the green model in the chart.
      The bubble chart marking the Standard card model
      Tip: Note the name of the model and its performance. The StandardCard model with the minimal performance of 50.35 requires immediate attention.
  1. Question - What is the performance of the two best-performing models?
    1. Hover over the two models in the middle of the chart.
      The bubble chart marking the best performing 2 models
      Tip: The two best-performing models are RewardsPlusCard with a performance of 69,49, and PremierRewardsCard with a performance of 80.40.
  1. Question - What is the performance of the two worst-performing models and what is the lowest number of responses?
    1. Hover over the smallest models in the chart.
      The bubble chart marking the 2 worst performing models
      Tip: The RewardsCard and StandardCard models have the worst performances, of 67.51 and 50.35 respectively, and the lowest number of responses of 1550 for each.
  1. Question - Which banner is the most successful?
    1. Hover over the model with the highest success rate in the chart:
      The bubble chart marking the model with the highest success rate of all
       
      Tip: The RewardsPlusCard has the highest success rate of 42.83%.

2 Inspect the predictors of the models

  1. Question - Which two predictors have the highest average performance across all models?
    1. Click the Monitor > Predictors tab.
      The Monitor-Predictors tab
    2. Click the Average performance column header twice to sort by the average performance.
      The list of the best performing predictors
      Tip: The two best-performing predictors are CreditScore and AnnuaIIncome. They are used in all 4 models because the # Models inactive value is 0.
  1. Question - Which predictors are not used in any of the models?
    1. Click the # Models active column header to sort the models in ascending order:
      The list of the inactive predictors
      Tip: The predictors with a # Models active value of 0 are currently not used in any of the models.

3 Inspect a specific adaptive model

  1. Question - What are the top three predictors used in the model with the best performance?
    1. Click the Monitor > Models tab.
    2. In the model list, click the Actual Performance (AUC) column header twice to sort the list of models in descending order.
    3. Click Model report in the first row.
      The model report for the best performing model
    4. On the Predictors tab, click the Performance (AUC) column header twice to sort the predictors in descending order.
      The list of top predictors of the model
      Tip: The top 3 best-performing predictors for this model are CreditScore, AnnualIncome, and Age.
  1. Question - Which predictor, which is not currently relevant for the adaptive model, has the highest performance?
    1. Scroll to the bottom of the list.
      The inactive predictor with the highest performance
      Tip: Customer.IsBankruptcy is the inactive predictor with the highest performance of 51.92.
  1. Question - Which age categories show the highest and lowest interest in this banner?
    1. Click the Age predictor.
      The Birthday predictor distribution chart
       
      Tip: The highest interest for this banner is in the last bins, with older customers.
