Creating Alternative Credit
Scoring Methods

Providing Innovative Credit
Scoring Methods

The Challenge:

Traditional credit scoring requires clients to have a credit history, and when they don’t they are either denied their applications or are given excessive interest rates. The challenge here was to build an alternative credit scoring system for small and medium enterprises (SMEs) to assess and understand their own financial health. 

The Factored Solution:

With a combination of machine learning and credit risk expertise, we built a set of models that allowed us to measure the credit health of SMEs using only transactional data from their bank accounts.

The Outcome:

We built a scalable web application for SMEs to link their bank accounts and ultimately monitor their own credit health.

 

The tech stack and skills we used to implement this include: PostgreSQL, AWS, Docker, Celery, Jenkins, GraphQL, Vue.js, Microservice-Oriented Architectures, APIs, Containerization, and CI/CD.

CUSTOMER SERVICE OPTIMIZATION

Customer Service
Ticket Categorization

Reclassifying Customer Service
Cases for Improved Service

The Challenge:

Customer experience agents are required to assign a category to customer inquiries regarding product improvement. This process takes a lot of human work, rendering it not only inefficient, but also vulnerable to misclassification. We needed to find a way to detect misclassified cases and assign them to agents for re-labeling.

The Factored Solution:

We used state-of-the-art NLP representation learning to detect when a category is misclassified and active learning techniques to balance out the volume of cases sent back to the agents. 

The Outcome:

Our system managed to detect 8 of every 10 misclassifications across more than 50 classes. The system was then extended to include the sending of the cases to agents for re-categorization.

 

We used a range of tech stack tools and skills including: TensorFlow, Docker, Flask, Natural Language Processing, Transfer Learning, BERT, ALBERT, Siamese Networks, Triplet Loss, and Deployment.
