Decision Trees
About the Data
The data has been split into two groups: training set (train.csv) and test set (test.csv)
The training set should be used to build your machine learning model.
For the training set, we provide the outcome (also known as the “ground truth”) for each passenger. Your model will be based on “features” like passengers’ gender and class.
The test set should be used to see how well your model performs on unseen data.
Even for the test set, we are providing the ground truth for each passenger, so that you can compute the required deliverables yourself.
But it is your job to predict these outcomes also.
For each passenger in the test set, use the model you trained to predict whether or not they survived the sinking of the Titanic.
Variable Notes
pclass: A proxy for socio-economic status (SES) 1st = Upper
2nd = Middle
3rd = Lower
age: Age is fractional if less than 1. If the age is estimated, is it in the form of xx.5
sibsp: The dataset defines family relations in this way… Sibling = brother, sister, stepbrother, stepsister
Spouse = husband, wife (mistresses and fiancés were ignored)
parch: The dataset defines family relations in this way…
Parent = mother, father
Child = daughter, son, stepdaughter, stepson
Some children travelled only with a nanny, therefore parch=0 for them.
Deliverables
The Python Notebook containing the complete, organized and well documented code with the following statistics:
Accuracy, Losses and F1 Scores for both Testing and Training datasets.
Instructions:
Create a Google Colab / Jupyter Notebook.
Explore the relationships between the output label and features. Plots are always helpful for such kinds of analysis.
Create a Decision Tree, which classifies the data into two classes (survived (1) or not-survived (0)).
(It is always helpful to plot losses and accuracy against these quantities to better understand how changing them is affecting your training process.)
(I recommend using Google Colab to avoid all the installation-related issues. You don’t need to install anything. You can work right from your browser.

How to submit the Assignments?
- Go to https://github.com/vanshbansal1505/ICG-Summer-Program-2021-DS/ and fork this repository.
- Push all the files that you want to submit in the appropriate folder of the forked repo. Name your folder“<Roll Number>_<Name>”(withoutquotes.)Strictlyfollowthisconventionineachof your submission otherwise it will be rejected.
(For example, if I want to submit the files x, y and z for the nth assignment, then I’ll put them in folder named 190941_VanshBansal and I’ll put this folder in the Assignment-n folder of my forked repository.)
- Create a pull request only during the submission window. All other pull requests will be rejected.
- Before the next assignment, fetch upstream your forked repo.
- Go to Step 2.
