Project Description
The project aims to build and evaluate machine learning models with the goal of predicting an individual's credit score with high accuracy based on their financial history and personal information. Implemented in R, the data was sourced from Kaggle and consisted of a large dataset with 100,000 rows and 28 attributes. Three powerful classification models – Logistic Regression, K-Nearest Neighbors (KNN), and Classification and Regression Trees (CART) – were implemented. Each model was trained with 70% of the data, and their performance was evaluated on the remaining test data, comparing accuracy and sensitivity across different cutoff values.

Conclusion:
The project successfully compared the performance of various models, identifying the superior one. A key takeaway was navigating through unclean data, emphasizing the importance of robust data cleaning processes for accurate model outcomes. The project provided an in-depth introduction to the implementation and evaluation of models in real-world problem-solving scenarios.
