Team Project: A Prototype for a decision support system that uses
predictive modeling
Predictive Analytics (CIS432, Spring B 2024)
Simon Business School
Instructor: Yaron Shaposhnik
Due date: Friday 5/3 at 10pm
Description: In this assignment, you will develop a predictive model and a decision support system (DSS) that evaluates
the risk of Home Equity Line of Credit (HELOC) applications (this is the same dataset you have been working with in your
homework assignments). The dataset and the description of the data are included in this assignment (you may find
additional information here: https://community.fico.com/s/explainable-machine-learning-challenge).
Details:
1. Design an interactive interface that sales representatives in a bank/credit card company can use to decide on
accepting or rejecting applications.
a. What did you assume about the technical proficiency of the user?
b. What did you assume about the model requirements?
c. How could the user explain predictions made by the model using the interface?
2. Develop a predictive model to assess credit risk
a. Report on the performance of your model.
b. Compare your model to other models.
c. Explain why you selected the particular model.
3. Develop a (running) prototype of the interactive interface
4. Prepare a report (up to 5 pages) that summarizes the key ideas of your work and describes your considerations
in making certain design choices.
5. Prepare a presentation (at most 5 minutes long) with a live demonstration of your system that covers the above
topics, and includes a discussion about lessons learned. Think about how to prioritize the content of the
presentation given the background of your audience (e.g., the teaching staff and fellow students that are
familiar with evaluation techniques and the models covered in class). All team members should present.
6. In both the report and presentation, discuss the limitations of your solution. Specifically, why would the
performance of your model after deployment could be worse than your pre-deployment evaluation?
7. The assignment is due Friday 5/3 at 10pm. Late submissions will not be accepted.
You may find the package Streamlit (https://www.streamlit.io/) useful for constructing the prototype (although you are
not required to use it). A video recording on the topic is posted on Blackboard (other tutorials are available on the
official website and youtube).
Teamwork: the assignment should be submitted in teams of 4-5 students. It is up to you to form the teams. Students
who do not find enough teammates (fewer than 4 students) will be matched with other teams. All teams should register
on Vocareum (even teams with fewer than 4 students). Please see the instructions below.
Submission: Use Vocareum to register your team and upload your submission (presentation, video, report, code). Note
that your solution may be shared online with other students.

Tips for teamwork
• Please start early – often tasks require more time than initially anticipated.
• Please be a good teammate – working in teams could be a fun experience when team members brainstorm ideas,
decide together on a course of action, and divide work effectively. It could also be frustrating when some
teammates are not responsive, are not flexible in scheduling times and on joint decisions, and when decisions are
made in subgroups that start early and “force” to other teammates to accept their decisions. Please try to be
respectful and professional towards your teammates. There is no optimal solution to this assignment, it is openended and there are many great solutions.
• Prioritize – you may not have enough time to develop the interface with all the software features you have in mind.
That’s ok – try to prioritize and implement a good solution with essential but fewer features.
• Try to have fun! While you may have other deadlines to worry about, most teams would get good grades for this
assignment. Try to use this assignment as an opportunity to connect to fellow students, reflect on the material
studied in class, and be creative in developing out-of-the-box solutions.

Registering teams on Vocareum
One student per team (a “team leader”) should invite the other team members.
4
The other team members should accept the invitations (through Vocareum, using the “Accept” link below)
This will show on the team leader’s screen (yellow message). Once all team members joined, the team leader should
click on “Finalize team”.
5
After finalizing the team, all members can click on “My work” to view the assignment files.
This opens the jupyter environment using which the team leader uploads and submit the files, which would later be
manually graded.
