📢Day 12/100: Comparing Machine Learning Models

Today, I compared the performance of multiple machine learning models for credit scoring:

1️⃣ Logistic Regression: Simple and interpretable but less effective with complex data.

2️⃣ Random Forest: Excellent for feature importance but slower for large datasets.

3️⃣ Gradient Boosting: Best overall performance with high accuracy and recall.

💡 Finding: Gradient Boosting stood out with an ROC-AUC of 0.97.

💡 Question: Do you prioritize interpretability or accuracy when selecting a model for financial applications?

📢Day 7/100: Tackling Data Availability in Ethiopia

Building a credit scoring model in Ethiopia has challenges, especially regarding data. 📊

Key hurdles I’m exploring:

1️⃣ Data scarcity: Formal credit histories are rare, but eCommerce and mobile money data offer untapped potential.

2️⃣ Local partnerships: Collaborating with fintechs to access anonymized transaction data.

3️⃣ Privacy compliance: Ensuring data protection laws are adhered to while innovating responsibly.

💡 Question of the day: Are there alternative sources of financial data that have worked well in other emerging markets?

📢Day 6/100: BNPL Risks in Emerging Markets

While Buy-Now-Pay-Later (BNPL) services are revolutionizing access to credit, they come with risks—particularly in emerging markets like Ethiopia. ⚠️

Key risks I’m addressing in my project:

1️⃣ Credit risk: Developing a robust scoring system to predict default probabilities.

2️⃣ Behavioral risk: Educating users to avoid overspending, especially first-time borrowers.

3️⃣ Operational challenges: Adapting BNPL models to Ethiopia’s infrastructure and regulatory environment.

💡 Discussion point: How can BNPL providers balance convenience with responsible lending practices?

📢Day 5/100: Understanding Ethiopian Fintech

Ethiopia's fintech ecosystem is a mix of challenges and opportunities. 📈🌍

From low formal banking penetration to an increasingly digital population, it’s clear that innovation in financial services is critical.

Key insights from my research today:

1️⃣ Low banking penetration but high mobile adoption: Over 75% of transactions are cash-based, yet mobile payment systems like Telebirr are gaining traction.

2️⃣ Regulatory frameworks: Ethiopia’s regulatory approach emphasizes financial inclusion but poses innovation challenges, especially for BNPL services.

3️⃣ Unique consumer behaviors: Ethiopians' dominance of informal financial systems and cash reliance shape their engagement with digital financial services.

💡 Question of the day: How can fintech drive financial literacy in Ethiopia to accelerate digital adoption?

📢 Day 4/100: The Role of Data in Credit Scoring

Data is the fuel for any credit scoring engine. 🔍

However, in Ethiopia, traditional credit data is scarce.

Today, I'll dive into:

Types of alternative data (e.g., mobile money, e-commerce behavior).

Ethical challenges in data collection.

I plan to build a framework that respects privacy while being effective.

📢 Day 3: Using RFM Scoring to Classify Customer Risk
📊 Before diving into machine learning or deep learning models, I started with a simpler yet powerful approach: RFM (Recency, Frequency, Monetary) scoring to classify customers into high-risk or low-risk groups.
Why RFM? In the context of Ethiopian BNPL services, where traditional credit histories are scarce, RFM provides a practical starting point by analyzing customer behavior:
1️⃣ Recency: How recently did the customer make a purchase?
2️⃣ Frequency: How often do they shop?
3️⃣ Monetary: How much do they spend?
This method helped me:
✅ Identify behavioral patterns to differentiate reliable customers from risky ones.
✅ Create a foundation for more advanced models
✅ Address data scarcity by leveraging transactional and engagement data.
RFM scoring is simple and interpretable, making it easier to communicate results to stakeholders early on.Next, I’ll integrate these insights into machine learning models to refine predictions and enhance scalability. 🚀
