Establishing a baseline on the HR Attrition data set To begin the pre-processing on the HR Attrition data set, I first imported the libraries I would need. I used pandas and numpy for data manipulation and numercial calculations. I also imported sklearn for preprocessing, ordinal encoder, train test split, classification report, confusion matrix and more. I also imported matplotlib and seaborn for data visualizations. I then read the data set and used the .head function to see the first 7 rows of the data set. I used the .info function to determine number of rows and columns, the data types of each columns and if any null values are present.

Feature Engineering Next, I set the y variable to our Attrition attribute, and the x variables to all other attributes in the data set. I then used the .replace function to set the Attrition values of Yes and No to 1 and 0, respectively. Then I used the ordinal encorder to change the data types on the variables. Finally, I converted the y variable Attrition to a string.

ML Modeling selections The machine learning models that I selected to are Random Forest Classification and Logistic Regression. I imported the machine learning algorithm and trained the model with the
