This is the solution of Programming Assignment of Machine Learning Course from Coursera which I have completed. By the time you finish this course, you’ll know how to apply the most advanced machine learning algorithms to such problems as anti-spam, image recognition, clustering, building recommender systems, and many other problems. You'll also know how to select the right algorithm for the right job, as well as become expert at ‘debugging’ and figuring out how to improve a learning algorithm's performance.
