I completed Andrew Ng’s Machine Learning Specialization course. And somehow, I’m still confused… Course 1: I’ve learned supervised machine learning, including regression and classification. Course 2: I’ve learned some advanced learning algorithms, like neural network and decision trees. Course 3: I’ve learned unsupervised machine learning, recommender systems, and reinforcement learning. But hey, I understood each concept (at some level), but my understanding is not holistic. I still have no idea how to use machine learning as a tool.

The other day, our tech lead suggested we implement supervised machine learning to automate our ticket approval system. He said it would be very easy. I had no idea how it worked-and honestly, I was confused. Why not just use if-else statements? Problem Statement We have a ticket approval system, a platform for reviewing tickets that request access to some resource. With an increasing number of tickets being submitted, manually reviewing them has become inefficient.
