Data analysis project in R

Diabetes risk classification and population segmentation using CDC BRFSS health indicators.

This project aims to compare traditional Machine Learning methods for tabular data classification, such as Ensemble methods, Decision Trees, and Naive Bayes, with NLP classification methods like Multinomial Naive Bayes, RNNs, and Transformers.
