1. We start by importing necessary libraries such as Pandas, Matplotlib, and scikit-
learn.
2. Next, we load the HR dataset (`hr_data.csv`) containing employee information,
including features such as age, department, salary, etc., and the target variable 'Attrition'
indicating whether an employee has left the company or not.
3. We perform exploratory data analysis (EDA) to understand the structure and
distribution of the data.
4. Data preprocessing: We convert categorical variables into numerical format using
one-hot encoding.
5. We split the data into training and testing sets using scikit-learn's `train_test_split`
function.
6. We train a Random Forest classifier on the training data to predict employee attrition.
