IBM Data Science
Capstone Project

Space X advertises Falcon 9 rocket launches on its website with a cost of 62 million dollars; other providers cost upward of 165 million dollars each, much of the savings is because Space X can reuse the first stage.
Therefore, if we can determine if the first stage will land, we can determine the cost of a launch. This information can be used if an alternate company wants to bid against space X for a rocket launch.
The goal of the project is to create a machine learning pipeline to predict if the Falcon 9 first stage will land successfully and also determine the price of each launch. .

Classification With Python

In this project, I built a classifier to predict whether a loan case will be paid off or not. I loaded a historical dataset from previous loan applications, cleaned the data, and applied different classification algorithm on the data. I used the following algorithms to build my models:
- k-Nearest Neighbour
- Decision Tree
- Support Vector Machine
- Logistic Regression
The results are reported as the accuracy of each classifier, using the following metrics when these are applicable:
- Jaccard index
- F1-score
- LogLoss
