About this Dataset

Adult Census Income Data

Below dataset contains three files:

adult_data.csv - train dataset
adult_test.csv - test dataset
adult_descr.csv - file with description of the data

In my kernel I start with looking what is presented in the dataset, what features are placed inside, what informations can be found and compared with eachothers, next I clean and prepare data into the form that is good for models I test. Starting with basic classification models, through hyperparameters tuning, ending on boosting algorithms I try to find best model, that is finally tested on the test dataset
