Exercise Statement

Part 1: Apply different Decision Trees to train a model for detecting breast cancer using the breast-cancer-wisconsin-diagnostic-dataset (scikit-learn 7.2.7. Breast cancer wisconsin (diagnostic) dataset). Goal is to predict whether breast cancer is Malignant or Bening.

Part 2: Apply various transformations, imputers, encoders-scalers using Pipelines with DecisionTreeClassifiers. Work with gridsearch to find the best parameters. Goal is to predict whether income exceeds $50K/yr based on census data.

Prerequisites

DecisionTreeClassifier Pipeline SimpleImputer StandardScaler OneHotEncoder ColumnTransformer GridSearchCV

Data source/summary:

Part 1: 569 instances with 30 numeric attributes. Class distribution: 212 - Malignant, 357 - Benign Follow the link below for the full description of the dataset. https://scikit-learn.org/stable/datasets/#breast-cancer-wisconsin-diagnostic-dataset

Part 2: income.csv is used for training set. 32561 instances with 14 attributes, 6 numeric (e.x. age, capital gain, hours-per-week ) and 8 categorical (e.x. workclass, education, race).

income_test.csv is used for testing and report scores. 15315 instances with 14 attributes, 6 numeric (e.x. age, capital gain, hours-per-week ) and 8 categorical (e.x. workclass, education, race).

Goal is to predict whether income exceeds $50K/yr based on census data. Link: http://archive.ics.uci.edu/ml/datasets/Adult
