Classified and clustered bank clients with respect to their user profile and decided if they should get credit. KNN & KMeans algorithms, K-Fold developed in C without libraries.

Credit Approval Application

Overview

A credit approval application which decides if a bank client should get credit or not. KNN and KMeans algorithms are used and implemented in C-language. For the validation of solution, K-fold cross validation is used.

Dataset concerns credit card applications. All attribute names and values have been changed to meaningless symbols to protect confidentiality of the data.
