I am trying to learn machine learning. As I believe in learning by doing, I started solving a machine learning problem on income prediction model. What should be the income of a person on the basis of title, skills, work experience, education, city, industry, etc.

Being a newbie I have the following doubts:

1. Which model should I use for this problem?
2. How should I approach this problem?
3. How can I deploy the machine learning model into AWS cloud and how can I connect with my existing web app?
