The default value for cp is 0.01 and that’s why our tree didn’t change compared to what we had at the end of part 2.. Another parameter to control the training behavior is tuneLength, which tells how many instances to use for training.The default value for tuneLength is 3, meaning 3 different values will be used per control parameter. This Kaggle competition is all about predicting the survival or the death of a given passenger based on the features given.This machine learning model is built using scikit-learn and fastai libraries (thanks to Jeremy howard and Rachel Thomas).

We tried these algorithms 1. 1. Predict survival on the Titanic using Excel, Python, R & Random Forests. Logistic Regression 2. In our initial analysis, we wanted to see how much the predictions would change when the input data was scaled properly as opposed to unscaled (violating the assumptions of the underlying SVM model). A key part of this process is resolving missing data. from the Titanic from a data platform Kaggle to find out about this survival likelihood. Although we have taken the passenger class into account, the result is not any better than just considering the gender. Note this is 1 - 21.32% we calculated before.
