I started the Machine Learning specialization. This week I learned about machine learning, supervised and unsupervised learnings and their popular algorithms like regression, classification, clustering, etc. I then went deeper to learn regression starting with univariate linear regression, writing cost function, mean squared error function and gradient descent and their implementation.
Congratulations on taking the most important step (the first one). Keep the excitement going. And please feel free to open up a topic here if you have questions or seek clarification on any of the concepts you are learning. Our volunteer mentors are ready to help.
