Kaggle Submission: Titanic
I've already briefly done some work in the dataset in my tutorial for Logistic Regression - but never in entirety. I decided to re-evaluate utilizing Random Forest and submit to Kaggle. In this dataset, we're utilizing a testing/training dataset of passengers on the Titanic in which we need to predict if passengers survived or not (1 or 0).

Cleanse Missing Data

#We have some missing data here, so we're going to map out where NaN exists
#We might be able to take care of age, but cabin is probably too bad to save
