After completing the Udacity "Introduction to Machine Learning Course" (which you can find here: https://www.udacity.com/course/intro-to-machine-learning--ud120), I used their pre-written code to develop my own testing of four machine learning algorithms I studied in the course, to achieve an F1 score greater than 0.3.
Everything here was prewritten code (or data) provided by the course, except for final_project/poi_id.py which is where I did the main developmnent to complete the project. To see my results, run that file using python3
The code was originally written in Python 2, I've made some small syntactical modifications to allow it to run in Python 3.9
