# Financial Inclusion in Africa - Zindi Competition
This repository contains my solution for the Financial Inclusion in Africa machine learning competition hosted on Zindi. The goal of the competition was to predict which individuals are most likely to have or use a bank account, based on demographic and socio-economic data from several African countries.
## Competition Overview
- **Objective:** Predict bank account ownership for individuals in Kenya, Rwanda, Tanzania, and Uganda.
- **Data:** Includes demographic, socio-economic, and household information.
- **Evaluation Metric:** Binary classification accuracy (and log loss).
- **My Result:** 🏅 **12th place** on the final leaderboard.
## Repository Structure
- `Train.csv`: Training data with features and target variable (`bank_account`).
- `Test.csv`: Test data for final predictions.
- `VariableDefinitions.csv`: Detailed description of each variable.
- `SampleSubmission.csv`: Example of the required submission format.
- `submission_enhanced.csv`: My final enhanced submission.
- `AfricaClassifier.ipynb`: Main notebook containing data exploration, preprocessing, modeling, and submission generation.
- `README.md`: This file.
## Approach
1. **Exploratory Data Analysis (EDA):**
- Analyzed distributions, missing values, and relationships between features and the target.
- Visualized categorical and numerical variables.
2. **Feature Engineering:**
- Label encoding and one-hot encoding for categorical variables.
- Standardization of numerical features.
- Handling of missing values and rare categories.
3. **Modeling:**
- Used LightGBM for binary classification.
- Hyperparameter tuning and cross-validation.
- Special handling for "uncertain" prediction cases using conservative and aggressive models for borderline probabilities.
4. **Submission:**
- Generated predictions in the required format.
- Analyzed and compared the impact of enhanced uncertainty handling.
## Results
- Achieved **12th place** on the Zindi le …
